        Aquaculture and environment have considerable interaction impacts on each other. In this study, the effect of education on environmental attitudes and behavior of trout farmers were investigated. The experiment was applicable using a researcher-made questionnaires and environmental training package. The validity of questionnaire was confirmed by the university professors and researchers of Fisheries Organization. Reliability of the Questionnaire with 15 tests showed Cronbach's alpha coefficient of 0.84. The statistical population was included 150 farmers with monoculture farms that their farms’ effluent had been discharged to surface water. The sample consisted of 63 persons in two control and experimental groups. The results showed inappropriate attitude of respondents before offering environmental training package (About 34% correct answers), while their acquaintance was significantly changed after presentation of the training package (p<0.05). Besides, 79% of respondents are not used any wastewater refining methods. However, training package could change behaviors in the experimental group and they announced readiness to wastewater treatment with low-cost procedures. No significant correlation was observed between age, education and aquaculture acquaintance with environmental behavior and attitudes. The results of present study showed that education had an important role in the environmental behavior of coldwater fish farmers, especially to prevent the pollution caused by farms’ waste water.

        Fish oil is one of the best sources of fatty acids dietary supply. Recently, use of fish oil isenhanced based on its useful effects on human health. Unfortunately, due to industrial pollution,many fish and fish oils have high levels of mercury. Mercury is one of the most poisonousmicroelement for the ecosystem. mercury is toxic and can damage the brain and the nervoussystem. The main object of this research was the assessment of Omega-3 fish oil pollution withmercury derived from shark and tuna fish in post-market surveillance in Tehran by cyclicvoltammetry. For this pupose fourteen fish oil brands was collected from market retail andtransferred to the laboratory. In this research, closed vessel microwave extraction and cyclicvoltammetric method was employed. The digestion process was perfomed via four steps in aconstant 50 bar pressure and a gradiant temperature from 145 to 200 ˚C. The mercury content offish oils was in the range of 11.03–107.11 ng/ml. Validation of parameters reveal that theprecision of developed method was 2.3 percent in mean standard deviation. In conclusion, fishsuch as swordfish and shark and tuna fish are also a source of exposure to the heavy metaltoxin, mercury. So the potential toxicity of omega 3 fish oil capsules with mercury must beconsidered and it is necessary to measure the mercury content of these capsules with a simple,precise, accurate and economic method.

        For this purpose, 360 Zebra fish were divided into two groups and fed for 60 days with commercial food (control group) or enriched diet with Lactobacillus fermentum as probiotic (test group). After this time, both groups were in the vicinity of 0.3 mg / l of lead and their survivability, tissue metal uptake and their histological damages were studied within 48 hours. Based on the results, the fish in the test group were able to tolerate the lethal dose of lead for more than 24 hours compared to the control group. After 48 hours of poisoning, the amount of metal uptake in both liver and gill tissue was significantly lower for the experimental group than in the control group. Moreover, tissue damage such as vein dilatation, lamella fusion and telangiectasia were significantly lower in the experimental group than the control group. Epithelial cell hyperplasia was not observed in the probiotic- treated group. It could be concluded that probiotic enriched diet can significantly reduce the toxic effects of lethal doses of lead in fish. Manuscript profile

        Background and Aim: In this study, a new overflow with a v-shaped structure was used as a barrier in the culvert. The main purpose of the present study was to investigate its performance on changes in flow resistance properties such as the square root of the Modi friction coefficient and the Manning roughness coefficient.Method:The present study experiments were performed on the physical model available in the hydraulic laboratory of the Faculty of Water and Environmental Engineering, Shahid Chamran University of Ahvaz. This physical model includes a laboratory flume 10 meters long, 0.25 meters wide, and 0.5 meters high. At the beginning of each experiment, the structures were glued to the flume bed at specified relative distances. After 24 hours of gluing the systems, the flume's flow rate and slope were adjusted. The desired flow rate was adjusted using a triangular overflow with an angle of 53 degrees located downstream of the flume and the slope through the jack. A point gauge with an accuracy of 0.1 mm was used to remove the water surface profile.Results: By increasing the dimensionless flow in a relative distance between structures and a certain slope, the manning roughness coefficient of the structure decreases. So that at a slope of 10%, the relative distance between the structures was 1.3, the value of the Manning roughness coefficient of the system from dimensionless flow decreased from 0.20 to 0.43 by 30%. By increasing the relative distance between structures at a certain flow rate, the manning roughness coefficient of the structure decreases, which is similar to the effect of the relative distance between structures on the square root of the friction drop coefficient of the structure.Conclusion: In examining the impact trend of the V-fish structure, it was found that dimensionless flow has an inverse effect on the flow friction coefficient and the manning roughness coefficient of the structure. On the other hand, the inverse relationship between landing number and flow friction coefficient, and manning coefficient of the structure was determined. It was found that the relative distance between the structures also has an inverse effect on the flow friction coefficient and the manning coefficient of the structure. The inverse effect of the Reynolds number on current resistance parameters was also extracted. The best condition of the fish road structure with v-shaped overflow occurs in the relative distance between the 1.3 and 10% slope structures. Manuscript profile

        Introduction: Gelatin is a natural biopolymer that is most widely used in food industry. Commercial gelatin due to its social, cultural and religious reasons are not acceptable by some therefore, gelatin extracted from fish processing waste might be employed as an alternative source for commercial gelatin. Materials and Methods: In order to optimize the extraction of gelatin from the skin of Iranian beluga fish ( Huso huso), the effect of different concentrations of NaOH (0.01, 0.05 and 0.075 N) and Ca(OH) 2 (0.01, 0.05 and 0.075N) on the extraction yield, melting point, viscosity, gel strength, colour and the molecular weight of extracted gelatin were investigated. Results: The results indicated that the highest extraction yield was obtained when 0.05 N Ca (OH) 2 was employed. The highest and lowest melting points (30.98 and 28.0°C) were related to the treatments concerned with 0.01N NaOH and 0.05 N Ca (OH)2 respectively (p< 0.05). The viscosities were increased as the alkali concentrations were reduced, however sodium hydroxide concentration affected the viscosity more than calcium hydroxide (p<0.05). Gel strength was affected more by 0.01N sodium hydroxide. There were not significant differences between the treatments concerning colour changes. Conclusion: The results indicated that 0.01 N NaOH treatment produced gelatin with improved functionality and characteristics. Manuscript profile

        Introduction: the health benefits of omega-3 fatty acids, as well as the high sensitivity ofunsaturated fatty acids to oxidation of fish oil, caused the use of encapsulation of fish oil forenriching food products and drugs.Materials and Methods: this study aims to evaluate the physicochemical properties of nanoencapsulatedfish oil, and their oxidative stability during storage at 0 and 24% relativehumidity conditions. Emulsion was prepared after sonication with wall materials ofmaltodextrin (M), modified starch (Hi-cap) and whey protein concentrate (WPC) at the ratioof 1:4 (oil:wall). Emulsion and nano-encapsulated powder properties including emulsionstability, apparent viscosity, powder moisture, encapsulated coefficient, particle size andmorphology of nano-capsules were determined.Results: The lowest amounts of creaming and viscosity were observed in M+Hi-cap+WPCand M, respectively. Moisture content in M+Hi-cap showed the highest value. The lowest andhighest particle sizes were measured in M+Hi-cap+WPC and M, respectively. Also, the bestencapsulation efficiency was obtained for M+Hi-cap+WPC. SEM photographs showed glasslikesheets of encapsulated materials with the freeze-dryer. During 21 days storage at 0 and24% relative humidity, the results showed an increase in peroxide and anisidine values. Thevalues were higher at 24% than the 0% humidity, and the best results of oxidative stabilitywere observed in M+Hi-cap+WPC treatment.Conclusion: Based on the findings, relative humidity is an effective factor in the oxidation offish oil nano-capsules. The use of nano-encapsulation is a practical and effective method forincreasing the stability of fish oil for enriching the food and promoting human health. Manuscript profile

        The aim of present study is to investigate physicochemical attribute, antioxidant function, antimicrobial activity and sensory feature in Lepidium latifolium L. (L. latifolium) extract on fish burgers during the shelf life. Initially, L. latifolium was extracted using soxhlet (LES), ultrasound (LEU) and supercritical water (LEW) as well as the major components were assessed using more performance liquid chromatography, which sinigrin and glucosinolates constituents were identified. The results illustrated that satisfactory values were obtained for these values in the treated sample by LEU; in next step, 0.2 % of each extract was added to fish burgers. The control and treated samples were tested to determine pH level, cooking yield, color features, thiobarbituric acid (TBAR), peroxide value (PV), microbial population, sensory evaluation and scanning electron microscope (SEM). The lowest TBAR and PV levels were found to be 0.38 and 0.40 (mg malonaldehyde) as well as 4.22 and 4.28 (meqO2/kg) for treated fish burgers by LEU and LEW, respectively (p < 0.05). The most sensory desirability was observed for treated sample by LEU, which also exhibited the uniform structure in SEM images compared to others. In conclusion, fish burgers obtained by LEU and LEW can be considered as optimal samples to preserve burgers. Manuscript profile

        AbstractBackground and Objective: Plans of fish farms is one of the human activities that can negatively affect water quality. So, reducing water pollution in output of fish farms is really important. In this study, in order to reduce water pollution output, a variety of filters made of natural materials are under investigation. One of the problems these filters can create is reducing of water quality by the materials used in them. So, the aim of this study was to investigate changes in water quality of fish farms in passing various materials for the production of filters. Method: To this purpose, a series of columns (PVC tube) with a height of 70 cm were used to investigate changes in pH-Ec and TDS. The tubes divided in half and in the middle of them was placed a geotextile layer. Then the variety of materials such as zeolites, beet pulp, wheat bran and maize to a height of 10 cm were poured into pipes and water continuously for 15 minutes from the column was passed directly. Then the inlet and outlet were taken samples at different times. Findings: According to the results, Ec and TDS values of output water are first increased and then decreased over time, so that the amounts mentioned increased in the beginning by 275.26 and 278.4 percent but have eventually returned to the initial amount of input water. Also, the pH of all treatments are different and increased in some treatments and decreased in others. Discussion and Conclusion: The comparison output water quality with the allowable output water quality in rivers showed in all the mentioned periods, the amounts are in normal limits and material used as a filter don’t create any problems on the quality of output water.

        Backgroun and Objective:Noise pollution caused by human activities is one of the types of environmental pollution. Anthropogenic noise level is increasing in both marine and freshwater ecosystems. Human activities have acoustically changed aquatic environments over the past decades and anthropogenic noise is now recognized as a ubiquitous pollutant in terrestrial and aquatic habitats. Shipping activities, wind mills, pile driving, seismic surveys, naval sonars and fisheries activities are all accompanied by the introduction of anthropogenic sounds in the water. Method: Here, we investigate how anthropogenic noise impairs behaviour and foraging activities, which has direct and indirect consequences for aquatic species survival and reproductive success. Findings: While a broad range of direct destruction caused by human activities in terrestrial and aquatic habitats is relatively well understood, there is a lack of knowledge about such activities on wildlife and captive species. For example, in laboratory condition, elevated sound levels may affect predator-prey interactions. We still have little understanding of the potentially negative consequences of noise pollution for aquatic life. Discussion and conculation: Changes in foraging tendency and efficiency may directly and indirectly affect relative species abundance of both predator and prey and induce changes at the community level.

        This research was carried out during 1382-83 on a monthly scale. The effect of sand and silt mining on Tonekabon river aquatic organisms was studied. One station was selected in sand and silt mining area and two stations were selected in upstream and downstream. The least abundance and biomass of benthic organisms was obtained in station 2 as 5%. This was also observed in estuary, as there were 21% and 74% of benthic organisms respectively in estuary and upstream of the reiver which have lost their habitates due to destruction of this area. Study on fish showed that Cyprinidae had the highest diversity and abundance. Fish abundance was 65% in station 1, 6% in station 2 and 29% in station 3. Station 2 had the least abundance. Migration and artificial propagation of Salmo truta caspius and Rutilus frissii kutum in this river are of high importance. Finally, destabilisation of river substrate and increase of suspended solid have led to reduction in diversity and abundance of species. The negative effects of sand and silt mining were not restricted to the sampling position and have affected other littoral parts of the river. This can result in degredation of river substrate and littoral parts                                                                                                                                 Manuscript profile

        One of the recent environmental problems is the presence of toxic, resistant and potentiallycarcinogenic compounds such as Malachite Green (MG) in effluent wastewater and fish tissues of fishfarms. The aim of this research is the measurement of MG in the effluent wastewater and fish tissuesof fish farms in Chahar- Mahal and Bakhtiari province.In this descriptive cross-sectional study, from total of 50 fish farms, five farms were selected fromthree categories of large, medium, and small scales of fish farms, based on fish production capacity.During three months, effluent wastewater and fish tissue samples were taken monthly and wereanalyzed to detect MG after preparation of the samples. MG analysis was done through Cloud PointExtraction method for effluents samples and liquid chromatography mass spectrometry (LC-MS)method for fish tissue samples.The results of this study showed MG concentration in the fish tissue of fish farms, No.: 1, 2, 3, 4, 5,and 6 were 1.6, 0.27, 0.26, 0.45, 0.28, 0.32 mg/kg, respectively. MG concentration in the effluent fishfarms were in the range of 5.7 - 273 ng/l.MG concentrations in the fish tissue in this study area are more than some of international standardssuch as Australia criteria of 0.03 mg/ kg for MG that shows the widespread use of MG in the fish1- Assistant Professor, Environmental Health Group, Faculty of Health, Medical Sciences of Shahrekord, Iran2- Associate Professor, Centre of Research of Environment, Group of Environmental Health Engineers, Facultyof Health, Medical Sciences of Isfahan, Iran3- MSc.

        Introduction:The present study was conducted to investigate the reasons for illegal hunting and fishing in Golestan and Mazanderan provinces during 2007-2008. Methods: In this study, the references such as books, papers, and magazines about the wild life and hunting laws were identified, and for this purpose, all the references in the existing libraries were studied. To find out the reason of crimes related to hunting and fishing, three methods were used: 1- Investigating the documents and records related to the last decade, 2- Providing an especial questionnaire for hunters, and 3- Providing an especial questionnaire for environmental lovers. Result and Conclusions: Results revealed that there were great differences, from different points of view, between the two provinces. Lack of rangers and deficient protective actions were the most important causes for hunting and fishing violations in both provinces. The questioners completed by hunters and fisrhemen showed that sport, recreation and especially need for food (meat) were the main incentives for violation. In both of the provinces, the rate of illegal hunting of wild animals in the areas under the management of Department of Environment (DOE) was higher than other violations.  Hunting types were quite different in both provinces. However, bird hunting had the highest rate among other violations. Distribution of the detected hunting and fishing instruments was not equal in both provinces and among their towns. Furthermore, types of hunting and fishing instruments were quite different, and there was an unequal distribution of illegal fishing and hunting of wild mammals, birds and aquatics among the towns. There was also a great difference in the range and manner of harms to the environment in the two provinces. Therefore, correlation coefficient was higher in Mazanderan province than Golestan province. Finally, based on the results and the diversity in the two provinces, in terms of types of crime and means of crime, some solutions were presented to reduce the mentioned crimes Manuscript profile

        Heavy metals and quasi-metals are among the stable and decomposing elements that threaten their health and human health if there are high concentrations in aquatic tissues. This study was conducted in 2017 with the aim of measuring the level of mercury metal contamination in the oral tissue of carp and duck fish in Anzali wetland, comparing it with the allowable limit of international standards and also examining the correlation between age, weight and diet with the level of contamination of this toxic element. Fish samples were collected from three parts of east, center and west of Anzali wetland. Mercury was measured with an advanced mercury analyzer (Leco AMA 254) according to the EPA6722D-standard method. The mean total concentrations of this metal in carp and duck muscle tissue were measured to be 0.598 and 0.5762 μg / kg dry weight, respectively. A significant linear positive correlation (p <0.001) was observed between mercury accumulation and age and weight of the two species. There was a significant difference between the concentrations of mercury in the muscle tissue of the two species. In general, the amount of mercury in the muscle tissue of fishermen was significantly higher than non-fisherman. The highest concentration of mercury was observed in the samples of the eastern part. A comparison between the concentration of mercury in the two fish and the US Food and Drug Administration's standard threshold for mercury (1 μg / g) shows that the results are below the threshold, while the threshold set by The World Health Organization and the Food and Agriculture Organization (FAO) are more.

        The story of the little black fish, due to its various expressive and allegorical relationships, provides a suitable platform for critique and analysis of the thoughts and ideas of various human characters using the relationships and behavioral characteristics of animals. With regard to this, the present study has expressed the allegorical effects of this story based on the theory of Leon Festinger, psychologist of social principles, in a descriptive-analytical manner and in a library method (studies of books and dissertations). The present is a photographer of the foundations of a society of a period and recognizes its various values ​​in the thoughts, ideas and culture of the people of a period, Political, moral, etc. in many works. The main issue of this research is the search for measures that Samad Behrangi has used to express his inner goals based on the prevailing concerns in society. So far, extensive research on this story. Has been done but no independent research has been done to explain its fictional relationships based on Festinger's ideas. The question discussed in the present study is to what extent the story of the little black fish can be examined on the basis of Festinger's principles of social incompatibility? Festinger's trivial thinking can be critically and practically examined. Manuscript profile

        The main purpose of using allegory is to illustrate the subject to the audience. An allegory that has not been investigated so far is the allegory of fish searching for the sea, which is important in terms of the analogy of the travel of birds to find the king. The allegory of fish is in search of the sea in a romantic masnavi named Ferdowsi Imam. This is Masnavi's self-portrait of a poet named Razi. At present, the authors of this speech tried to correct this allegory in other Persian works. The results of the study showed that the allegory of fish in search of the sea has been used repeatedly in various works and the aim of most authors is to insert this allegory into mystical concepts, in particular the unity of existence. Most of these authors are from the students of Ibn Arabi's school. This allegory is also used by the Sacred Sect to express their religious beliefs. The phrase, which was at the end of the Safavid era, narrates this parable in a romantic narrative. Manuscript profile

        Inroduction and Objective: Sardines and other microfilidae have very important ecological role in marine ecosystems because they  are first consumers in marine food chain and they are the main food of valuable species as tuna. So decries in their population will decline fishing of these spices. There are 10 genus of Cloupeidae in south of Iran and Sardinella sindensis is the  one of the most abundant of  them. In this study we investigated about morphological differences in population of this speciesMaterials and Methods: About 63 specimens from three regions of its distribution: Jask (Oman sea), Qeshm ( Hormoz ) and Lengeh (Pearsian golf) have been collected. Morphological  research of their characters  and statistical studies were done with One-way ANOVA and MANOVA.Results: Statistical studies show a meaningful morphological difference between characters and also a cline from Lengeh to Jask port which might be a result of  creation of subpopulation in this fish. Post- hoc analysis show that in all characters jask has a meaningful different with gheshm and lengeh.

        Inroduction & Objective: Ibuprofen, as a drug contaminant, has deleterious and in some cases irreversible effects on aquatic organisms and in general on living things, which in many cases can result in genetic damage and damage to the DNA structure. The effects of different concentrations of ibuprofen on DNA damage and damage to zebrafish are investigated. In this study, genetic changes of p53 gene and its expression in zebrafish after two weeks of exposure to 0.1, 1 and 10 mg / l ibuprofen in vitro were investigated. Material and Method: In this study zebrafish were exposed to the above mentioned concentrations for two weeks and then RNA extracted from them. The results were analyzed using QPCR method. Results: The low drug, 0.1 mg / l had no effect on p53 gene expression, while the other two concentrations, which were 1 and 10 mg / l ibuprofen, respectively, showed a significant difference between the control and the drug containing sample. As a result, the p53 gene was highly expressed. Also for the internal control gene that was GAPDH, there was no significant difference at the lowest drug concentration. Ray did not show a significant difference between the treatment and control samples, while in the subsequent treatments there was a significant difference between control and treatment samples.The final result of this study was that p53 gene expression increased 1.09, 0.57 and 2.2 fold in sample with lowest drug concentration, mean concentration and highest drug concentration, respectively.

        Introduction & Objective: Common operations during reproduction and breeding or during research studies often cause stress and physiological responses in fish, which subsequently lead to adverse effects such as immunosuppression, delayed growth, and death. The objectives of this experiment were to evaluate the efficacy of benzocaine as an anesthetic in goldfish (Carassius auratus). Moreover, the effect of anesthesia with effective concentrations of benzocaine and stress caused by manipulation on hematological indicators was studied.Materials & Methods: For this purpose, ten fish individually were exposed to 50, 75, 100, 125, 150 and 200 mg/L benzocaine, and time to induction (deep anesthesia) and recovery from anesthesia were measured. In the second experiment, 7 fish were deeply anaesthetized with 125 and 150 mg/L benzocaine. Subsequently, Fish were subjected to stress by acute handling, blood sampling and maintaining them out of the water for 2 min. for assessing possible stress effects caused by acute handling, blood was collected as described above without anesthesia. In control group, fish immediately after netting with their head covered with wet cloth to reduce stress, blood collection was performed by cutting caudal peduncle and lasted less than 15 s.Results: At concentration of 50 mg/L, benzocaine failed to induce deep anesthesia in fish within the 10 min exposure period whereas at concentrations of 125, 150 and 200 mg/L, all the fish were anaesthetized within 3 min of exposure. Induction and recovery times for benzocaine were significantly dependent on concentrations (P<0.05). Hematological results between groups showed no significant changes in white blood cell count and hematocrit level. Acute handling caused significant increase in hemoglobin, red blood cell count, serum glucose and cortisol levels compared to control and anaesthetized group (P<0.05).Conclusion: This study demonstrates that rapid induction of deep anesthesia with a relatively high concentration of benzocaine (125 mg/L) block the stress-induced cortisol response with the lowest effects on the hematological and serum biochemical indices in gold fish and therefore would be recommended as eligible dose for handling and hematological studies in this species.

        To investigate the effect of active composite coating carboxymethyl cellulose-based on the shelf life of rainbow trout (Oncorhynchuus mykiss) fillet during refrigerator temperature storage, an experiment for 12 days with 5 treatments including uncoated (control), carboxymethyl cellulose 1%, carboxymethyl cellulose-oleic acid 1%, carboxymethyl cellulose-oleic acid-Echinacea extract (0.5% or 1%) and 3 replications was carried out. Chemical (PV, TBARS, and TVN) and microbial (TVC and PTC) tests were performed on the fillets every 3 days. The results showed that oleic acid improved the protective effect of carboxymethyl cellulose coating. The antioxidant and antibacterial effect of Echinacea extract was concentration dependent. At the end of the storage period, the lowest values of PV (3.90±0.11 meq/kg), TBARS (1.24±0.27 mg MDA/kg), TVN (21.90±1.83 mg/100g), TVC (5.10±0.10 log cfu/g) and PTC (5.23±0.06 log cfu/g) were found in fillets containing active composite coating of carboxymethyl cellulose-oleic acid-1% Echinacea extract (P <0.05). Therefore, the composite coating of carboxymethyl cellulose-oleic acid-1% Echinacea extract can be used as an active packaging to maintain the quality and increase the shelf life of rainbow trout fillets during short-term storage at refrigerator temperature.

        Increasing level of population and elevated demand for more food production has led to higher protein need from animal sources like cattle, poultry and fish. Moreover, due to lower production cost, less physiological side effects and environmental pollutions, animal breeders are eager to use other potential protein resources such as insects and mollusks. Seven species of invertebrates were evaluated in this study: American cockroach, Italian grasshopper, honey bee, leech, Sunn pest, slug and snail. Several parameters were analyzed in all the species including fat by using Soxhlet method, protein by Kjeldahl method, calcium and phosphorus by colorimetric method, relative humidity, dry biomass, fiber by Fibertech method, energy, ash and carbohydrate by Manson-Walker method. According to the results, it could be concluded that among the studies species, American cockroach with high level of protein, calcium, dry biomass, fiber, phosphorus, energy and low level of fat could be a valuable option for poultry and fish food regime.

The obtained data were analyzed by ANOVA, and the groups were compared by Tukey test. Average of the morphometric characters in the rivers was 7.4, 10.06, 10.46, 12.36 and 12.75 percent, respectively. Due to significant difference (P &lt;0.01) in the mean of studied parameters and high coefficient of variation among five rivers, the whitefish were different. The average of coefficient of variation in most morphological traits increased from western estuaries to eastern one, and the difference of traits is proportional to estuaries distance. Sefidrood showed the highest differences in morphometric traits and the lowest one was observed in Chelvand. The average of coefficient of variation of nine meristic traits in above rivers was 6.56, 6.48, 6.36, 6.36 and 11.5% respectively, and seven of them have no significant difference. The results showed that independent&rsquo;s of spring whitefish are in the studied rivers , but due to the low mean coefficient of variation in the meristic characters of them, probably the environment has been effective in the population&rsquo;s diversity.

        To compare the yield and yield components of direct seeded rice cultivars along with fish culture, a field experiments was conducted in a randomized complete block design with three replications and ten treatments in Astara during 2012 growing season. Analysis of variance of the data collected showed that there were significant differences among the traits of rice cultivars at %5 probability for panicle length and at %1 probability level for plant height, seed diameter, panicle weight, 1000 kernel weight, No. of kernel per panicle, straw weight and paddy yield. Mean comparisons showed that Gohar among the cultivars under study due to its high yield potential with average 6378 kg/ha was the most suitable cultivar under direct seeded rice along with fish culture. Producing 1100.82 kg/ha of fish in rice fields not only increases farmers income it also reduces production costs. These results, consequently, justify the possible extension of rice-fish production as a sustainable agricultural system in rice growing regions of Astara and similar areas of Iranian Caspian coasts.

        AbstractAmmonia toxicity is one of the most common types of poisoning in fish, which sometimes manifests itself in acute and sometimes chronic forms. Ammonia enters the water from various sources such as industrial wastes, agricultural runoff, and decomposition of microorganisms living in water and as the final excreta resulting from the catabolism of proteins and amino acids in aquatic animals. Ammonia poisoning is associated with a wide range of symptoms due to the concentration of this substance. These symptoms can range from simple behavioral changes to severe neurological symptoms and death. Fish adopt different strategies when this poisoning occurs; these include reducing nutrition, reducing protein metabolism, detoxifying ammonia and turning it into less toxic substances. Almost all fish organs respond to ammonia poisoning, but organs such as the liver, gills, muscles, and brain play a more prominent role in the development of symptoms, condition control, and detoxification. Understanding the biochemical mechanisms of these organs in the face of ammonia toxicity and understanding the pathophysiology of this toxicity can help prevent or manage this poisoning if it occurs. Of course, not all fish species respond the same way to ammonia toxicity, and some species that are more resistant may be better breeding options. Manuscript profile

        As the use of wood plastic composites (WPC) in various industries has increased significantly and due to the high importance of environmental issues in industry and research and the fact that products made of petroleum polymers have too little biodegradability, it is important to conduct research to improve and solve this environmental problem. Due to the high amount of volatile nitrogen, low quality fish powder is not used in the industry, and as a result, it can be use as cheap and biodegradable filler in wood plastic. In this research, the effect of fish powder amount, substrate type, and coupling agent (MAPE) amount on the physical characteristics of wood-plastic composite was investigated. The results showed that by increasing fish powder amount and decreasing coupling agent amount, the highest amount of degradability is obtained. Manuscript profile

        Abstract[1]Green tea extract which contains high amount of poly phenols is known as effective anti-oxidants due to anti-bacterial and anti-virus effects of poly-phenols. The main objective of this study was to compare the effects of lowring temperature (3-5 oC), Green Tea Extract (GTE) (800 ppm) and Modified Atmosphere Packaging (MAP) (condition 50:5:45 for N2:O2:CO2) with normal or Aerobic packaging (AP), on the chemical and sensory characteristics of SCM within refrigerated storage. Results of Peroxide Value showed that all treatments can effectively protect SCM against oil oxidation, compared with AP, after 4 days. Using MAP and/or GTE treatments reduced the Free Fatty Acid (FFA) formation ratio, because, in contrast with AP treatment, FFA increased significantely (P&lt;0.05), only after 16 days storage. Thiobarbitoric Acid Reactive Substances (TBARS) of AP samples in 16th days was 2.51&plusmn;0.21 mg that was upper than accepted limits. Effects of GTE treatment on TBARS increasing was not significantly different compared with AP (P&gt;0.05). pH trends was ascending and GTE and MAP treatments had no significant effects on pH increasing. According to sensory evaluation, MAP had higher total quality score compared with GTE treatment and showed no significant difference with MAP+TE during storage. Combined treatment (MAP+GTE) was selected as an effective method that can extend the shelf-life of SCM up to 4 days at refrigerated storage.*Corresponding authors; fnoghani@yahoo.com Manuscript profile

        Fish and shrimp are very good sources of nutrients such as omega-3 fatty acids, vitamin D, and protein, so they form an important part of people's diet; However, seafood can bring risks for consumers, so the purpose of this study is to investigate the prevalence of Vibrio types in fish and shrimps caught in Qeshm city, Iran. In this study, 250 samples, 50 of each sample, including salted fish, Halvasfid, milkfish, shoe fish, and shrimp, were randomly taken from the beach of Qeshm City and transferred to the food hygiene laboratory of Shahrekord Azad University. The samples were tested according to the standard method of searching for Vibrio species. SPSS version 23 statistical software and chi-square statistical test were used for data analysis. The limit of significance in this study was considered (P&lt;0.05). The results showed that the highest level of contamination among Vibrio was related to parahaemolyticus with 74% of contamination and the lowest level of contamination was related to alginolyticus with 14% of contamination. The contamination rate of salted fish, Halvasfid, milkfish, shoe fish, and shrimp were 30, 16, 6, 24, and 23% respectively. In this study, the risk of consuming raw, half-cooked, or undercooked products is clear. Therefore, it is important to pay attention to the hygiene principles after catching, i.e., freezing until the time of consumption and adequate cooking of the product. Manuscript profile

        Byproducts from the processing of fish are a good source of collagen. Biodegradable protein-based film was made by incorporating clove essential oil (CAO) into Caspian white fish scale gelatin (CWFSG) at level of 0, 0.5%, 1% and 1.5% (weight/ protein weight ratio) and antimicrobial, physical and mechanical properties of films including tensile strength (T.S), elongation at break (EAB%), moisture%, water vapor permeability (WVP), contact angle, solubility, surface color properties, and scanning electron microscopy (SEM) were investigated. Gelatin-based films enriched with different concentrations of CAO were prepared and examined. Incorporation of CAO at concentrations of 0-1.5% resulted in the decreasing in tensile strength (TS) of the films. Water vapor permeability (WVP) was increased in the film added with CAO at a level higher than 0.5% (P&lt;0.05); However, film solubility and L*value decreased. Moreover, when CAO was incorporated the films showed the lowered light transmission in the visible range. Films incorporated with CAO had an inhibitory effect in a concentration-dependent manner against Staphylococcus aureus, Listeria monocytogenes, and Escherichia coli. SEM images revealed the presence of micro-pores in the essential oil incorporated films, which contributed to the physical properties of the films. Gelatin films incorporated with CAO can be used as an active packaging, but the properties must be modified. Gelatine film containing 1% CAO had the best physical, mechanical and antimicrobial properties. Manuscript profile

For this purpose, crayfish specimens were captured with 45 total samples from three permanent lakes and transported to the laboratory. Preparing of their tail meat as the edible parts and measuring of heavy metals (Cd, Cu, Ni, Pb, and Zn) have been accomplished via the wet digestion method and atomic absorption spectroscopy (AAS), respectively. Results showed that Cd (0.004&plusmn;0.003) and Zn (2.61&plusmn;0.747 &micro;g/g DW) were the minima and maximum concentrations in the tail meat of Haft Barm&rsquo;s crayfish. Since the concentrations of all measured trace elements were within the permissible limits of hygienic standards (WHO and FAO) and based on health risk assessment (daily intake index), Haft Barm&rsquo;s crayfish have admissible health in terms of their accumulation. Hence, daily and continuous consumption of these aquatic products by consumers has been thoroughly safe, and there is no risk for them in this regard. Manuscript profile

        Staphylococcus aureus beyond the cause of food poisoning, can cause wide spectrum of infections in human and is a serious threat in food industry. This study was conducted to evaluate antibacterial effect of alcoholic extract of garlic (Allium sativum) alone and in combination with nisin on inhibition of Staphylococcus aureus in minced meat of the tilapia fish. Garlic Extract was prepared by vacuum evaporation method using the rotary device. The effects of different concentrations of garlic alcoholic extract (0, 1, 2.5, 3.5, 5%) and nisin (0, 0.5 and 2.5 &mu;g / g) and the combinations of nisin (micrograms per gram) and Extract (%) (0.25+3.5), (0.25+5), (0.5+1), (0.5+2.5), (2.5+1), (2.5+2.5) were studied on the growth of the S. aureus at 4 &deg; C for 21 days. The results showed that the bacterial growth was stopped at 3.5% and 5% concentrations of garlic extract from days 12 and 9 respectively, and It was stopped at 0.5, 2.5 &mu;g/g of nisin from days 9 and 6 respectively. Low concentrations of garlic extract (1 and 2.5%) did not inhibit the growth of bacteria. Combined treatments of extract and nisin were able to stop bacterial growth from day 6 onwards. According to this study, garlic extract and nisin have inhibitory effect on growth of bacteria and they are introduced as a natural preservative of food instead of chemical preservative. This research approved the synergistic effect of nisin and alcoholic extract on the inhibition of the S. aureus growth. Manuscript profile

        Salting of fish is a traditional method for fish preservation which reduces corruption, increase shelf life and is used in order to have an access to the new markets. In some countries, consuming semi-cooked or raw salted and smoked fish is well-liked. Due to the presence of halophilic microorganisms in salted fish, occurrence of food-borne infections is probable. The aim of this study was to investigate the antimicrobial activity of NaCl on Staphlococcus aureus and Listeria monocytogenes in salted silver carp. Effect of different concentrations of NaCl (4, 8, 12 %) on behavior of Staphlococcus aureus and Listeria monocytogenes in 10˚C during 3 weeks (0, 1, 2, 3, 6, 9, 12, 15, 18, 21 days) was determined by evaluation of the bacterial growth in salted fish fillets. Statistical analysis showed that application of different concentrations of NaCl had significant inhibitory effect on the growth of S. aureus and L.monocytogenes in salted fish fillets compared to control group (p&lt;0/05). This study indicated that application of NaCl without any complementary element is not considered as a good preservative for extending the salted fish shelf-life. Consequently using of other natural preservatives along with salting is suggested. Manuscript profile

        Histidine is one of non-protein nitrogen extractives which found in fish such as Salmonidae family (trout is belonged this family).Members of this family has high amounts of Histidine compared to other foods. Some Salmon microbial flora can decarboxylated Histidine to Histamine and this metabolite is a hazard component for human. Evaluation of Histamine levels in Salmon via a fast and accurate method can be useful for decreasing the intensity of these hazards. In this study evaluated psychrophilic and mesophilic aerobic bacteria and also histamine level in purchased salmon samples from fish markets in Tehran by ELISA method (Rida Screen Histamine Kits). A total of 60 samples of Rainbow trout (Oncorhynchus mykiss) purchased from fish markets and assayed for Histamine by using Rida Screen Histamine ELISA Kits. Bacterial enumeration was performed on 10-fold diluted samples at 25&deg;C and 35&deg;C for mesophilic and psychrophilic bacteria, respectively. The range of Histamine content was 4 to 28mg/100g (14.18mg/100g). 12.50 percent of samples had Histamine content above the international standard level (20mg/100g). Data achieved by bacterial enumeration and ELISA test were analyzed by Pearson correlation test indicated that direct relationship between histamine and the number of bacteria in fish samples is established (p&lt;0.01). Variations in amounts of bacterial decarboxylase enzyme in all kind of fish depends on with time &ndash; temperature storage, fish species variation and kind of seafood. Therefore, application of good health care during the various stages of breeding, fishing, transportation and storage in inhibition of&nbsp; bacterial growth and subsequent production of histamine is effective and the risks of histamine poisoning can be minimized thereby. &nbsp; Manuscript profile

        &nbsp; &nbsp;Nowadays, the entrance of heavy metals in the aquatic environment is an important and also a global environmental concern due to the indiscriminate discharging of various industrial wastewaters, which cause accumulation of heavy metals in body of aquatic animals including fishes. The present study aimed to evaluate the amount of Chromium and Vanadium in muscle tissue of Chondrostoma regium and Cyprinion macrostomum fish in Kermanshah Gharasou River in 2013. For sampling eight different places were chosen along the river and according to places of discharging municipal and industrial wastewaters. A total of 10 samples were collected from each place and all samples were analyzed for determination of Chromium and Vanadium metals using atomic absorption spectrophotometer. Based on results, mean concentrations of Chromium and Vanadium in muscle tissue of investigating different species among all places were significantly different (P &lt;0.05). The minimum amount of Chromium and Vanadium content was observed at the 3 and 8 sampling stations; while the maximum quantity was determined at the 6 and 8 stations. Results revealed that mean content of Vanadium at the 3, 4, 5 and 6 station was significantly lower (P &lt;0.05) than the standard limit approved by WHO, however, at the other stations the Vanadium content was significantly higher (P &lt;0.05) than the WHO limit. The estimated Chromium quantity of all stations was higher than the FDA and WHO standards (P &lt;0.05). Comparing the results of the present study with findings of other researches and also existing standards (FDA and WHO) indicate high levels of Chromium and Vanadium residues in muscle tissue of fishes. High loads of Pollutants with different types of industrial and municipal wastewater in Kermanshah Gharasou River are the major cause of heavy metals residues. Therefore, it is crucial to apply practical approaches to reduce these pollutants in Gharasou River. Manuscript profile

        Apart from skin, gills are the first place of direct exposure of fish to toxins or pollutants therefore study of changes in gill structure is a suitable indicator of toxins or pollutants under stressful conditions. The aim of this study was to investigate pathological alterations of gill tissue in common carp during exposure to different nanoparticles. For this study, 210 fry common carp with a total length of 7.36&plusmn;0.30 cm and goldfish with a total length of 6.50&plusmn;0.43 cm in 6 treatments with 3 replicates in each treatment were placed in 60 liter aquariums in groups of 11 individuals. Gill tissue samples of common carp and goldfish were taken 7 days after exposure to 50% lethal concentration of nano-zinc oxide, nano copper oxide and titanium dioxide nanoparticles. Histological changes were evident in samples exposed to nano-zinc oxide, nano copper oxide and titanium dioxide nanoparticles while no detectable changes were observed in control gill. The symptoms observed in both fish consisted of gill hyperplasia, adhesion of secondary lamellae, increased levels of mucus and hyperemia. The most common complication observed was gill hyperplasia and an increase in the amount of mucus. The results of this study indicate that 50% lethal concentration of nanoparticles of titanium, copper and zinc can cause tissue damage and destruction. Also, sub-lethal toxicity of nano-zinc oxide is higher than nano copper oxide and nano titanium dioxide and causes much wider effects on gill tissue of common carp and goldfish.&nbsp; Manuscript profile

        Parasitic infections cause huge losses to the aquaculture industry by reducing production. Identification of parasites is necessary to prevent infections and parasitic diseases of fish.Theparasitic fauna of fishes in Fahlian River has not been determined yet. This study was carried out to identify parasites in selected cyprinid fish in Fahlian River of Mamasani, Fars Province. For this purpose, 85 cyprinid fish of 3 species including Alburnus mossulensis, Cyprinion macrostomum and Capoeta barroisi persica were caught from 3 stations of Fahlian River in 2014 and examined in terms of visceral parasites. A total of 4 parasitic species were isolated and identified, including 1 digenean trematode (Allocreadium sp.), 1 cestode (Bothriocephalus sp.) and 2 nematodes (Rhabochona sp. and Cuculanus sp.). The highest and lowest percentage of parasitic infestation was related to Allocreadium sp. and Bothriocephalussp. respectively. Also Capoeta barroisi persica and Cyprinion macrostomum demonstrated the highest and the lowest percentage of parasitic infection respectively. There was no significant relationship between infection of fish species and the infected organs. Based on the results of this study, all the studied fish (except Rhabochona sp. which was previously isolated from Cyprinion macrostomum) were introduced as new hosts of Allocreadium sp., Bothriocephalus sp., Rhabochona sp. and Cuculanus sp. in Iran.

        Ichthyophthirius multifiliis is one of the most important ectoparasites in ornamental fish causing economic losses. Although many different methods are being applied to reduce the prevalence of the disease but it is recommended to adopt preventive methods such as using immune stimulative materials like probiotics to support immune system of fish. This study was conducted to evaluate the effect of Bacillus subtilis probiotic on experimental infection of gold fish by Ichthyophthirius multifiliis. In order to do the research, 32 nearly same sized gold fish was used in two groups of 16 fish as the control and treatment groups and then the treatment group fishes was fed with Bacillus subtilis probiotic enriched pellets for eight weeks and after this time, the groups were experimentally infected with Ichthyophthirius multifiliis parasite and were tested for parasitological and histopathological purposes. Parasitological examinations revealed that the infection rate of the parasitic disease was significantly lower (P&lt;0.05) in the treated group compared to the control group, in such a manner that the number of the parasites were 107 and 276 in the treatment and control groups, respectively. Histopathological examinations also showed that the fish in the control group had more lesions than the treated group (P&lt;0.05). Manuscript profile

        &nbsp; &nbsp;Aeromonas hydrophilia&nbsp; &nbsp;is the etiologic agent of motile aeromonas septicaemia, one of the most important bacterial diseases of fresh and marine water fishes. The aim of the present study was detection of A. hydrophilia in the aquarium goldfish and cultured rainbow trout in Chaharmahal va Bakhtiary province.&nbsp; In this study 50 goldfish from aquarium fish shops and 60 rainbow trouts suspected of having the disease from 6 farms (10 fish in each farm) were randomly collected. The average weight in goldfish and rainbow trout samples were 3-5 g and 10-20 g, respectively. Sampling was performed from kidney and liver, and inoculated into blood agar and incubated at 22&deg;C for 24 hours. Pure colonies which are grown on the mediums were tested by catalase, oxidase and gram staining, then those of gram-negative, catalase and oxidase positive were diagnosed, and cultured on Shotts-Rimler medium (as selective medium for A. hydrophila). These mediums were incubated at 22 &deg;C for 24-48 h. The typical colonies were tested by using oligonucleotide primers of lip gene by PCR method. In light of molecular analysis of all specimens, 9 and 6 isolates from rainbow trout and gold fishes were identified as A. hydrophila respectively. Due to the detection of A. hydrophila in both cultured rainbow trout and aquarium goldfish, the bacteria can lead to septicemia with mortality if the health management principles are not observed in fish farming.

        The aim of the present study was to determine the optimal time of fish oil inclusion in broiler feed formulation on antibody response and concentration of serum cholesterol and triglyceride. A 49 day study was conducted on 600 one-day old chicks from a commercial hybrid (Ross) which were randomly allocated to 6 groups. The control group was fed a diet containing 5 % corn oil and in experimental groups the fish oil was substituted for corn oil from 2,3,4,5 and 6 weeks. Serum concentration of cholesterol and triglyceride were determined on days 37 and 44. Titer of antibody against sheep red blood cells (SRBC) were determined 7 days after immunization on days 30 and 37. Supplementation of diet by fish oil did not affect concentration of serum cholesterol. However, concentration of serum triglyceride decreased significantly (p&lt;0.01). Titer of IgG against SRBC was affected in first injection (p&lt;0.01) and the maximum antibody response was seen in control group and chickens feeding fish oil for 2 weeks, and antibody response decreased with increase of consumption length of fish oil. Titer of IgM in the second injection (p&lt;0.05) were affected by dietary treatments. Chickens which were fed fish oil for 2, 3 and 4 weeks had higher antibody response than other treatments.&nbsp;&nbsp; Manuscript profile

        Water has always played an important and decisive role in the formation of the human civilizations, including the Elamite civilization. Since the early human had defined god symbols for every phenomenon important to him, he also defined the gods of water in all civilizations. It is also known that in the Elamite civilization, since its earliest civilization, water gods and their creatures have always had a special place, including creatures. Those who were associated with the gods of water and the creatures of the gods Ea/Enki waters' deities have been seen among the Elamite motifs and works since ancient Elam. Of course, given the limited resources available to Elamite civilization, as well as the interplay between the two Elamite and Mesopotamian civilizations, and the greater diversity of interpersonal resources, the role, and status of fish-women should be examined in light of their background in Mesopotamian civilization. This is not, of course, due to the complete conformity of these concepts in these two civilizations, but, due to the lack of Elamite resources in this respect, the closest concepts to Elamite concepts can be found among the sources available among the interpersonal concepts. This article is based on the library study method on the existing evidence and it seeks to study the role of the fish-women in the Elam civilization. Manuscript profile

        This study was carried out to investigate the possibility of using Ulva intestinalis macroalgae extract as a natural antibacterial agent in Beluga minced meat. For this purpose, the minimum of inhibitory concentration (MIC) of the hydroalcoholic extract of the algae was determined in vitro by micro-well dilution method against Listeria monocytogenes pathogen. Then, the concentrations of controls (without any additive), BHT (as a synthetic antioxidant), MIC, 2 fold of the MIC (2MIC) and 3 fold of the MIC (3MIC) concentrations, were mixed with minced meat and refrigerated. Microbial properties of the samples including psychrophilic bacteria count, mesophilic bacteria count, Pseudomonas count and Enterobacteriaceae count were measured at 0, 4, 8, and 12 days. According to the results, the MIC was 12.5 mg/mL. The result of this study showed that the samples with the algae extract had less microbial load in comparison with control and BHT groups (p &lt;0.01). Also, 3MIC showed the most antibacterial effect among other algae extract treatments by the lowest amount of mesophilic bacteria (6.27 Log cfu/g), cold (09.08 Log cfu/g) Pseudomonas (6.6 Log cfu/g) and Enterobacteriaceae (6.21 Log cfu/g) population size at the end of storage period. The results indicated that grass kelp macroalgae is a suitable species for use as a natural preservative, and the minced fish with three fold of the MIC concentration had less bacterial spoilage during the storage period in a refrigerator.

        Zoonoses involving transmission of disease and biotoxin producing agents from fish to humans have been documented in the literature mostly including bacteria, biotoxins and parasites. The list of potential fish-borne zoonoses is quite large. Twenty six infectious agents are discussed in this review and there are also many other infectious organisms of fish origin that have not been reported but have the potential to infect and harm human. The status of the human host immune system plays a vital role in the severity of the disease. The major exposure routes include ingestion and introduction of organisms through open wounds or abrasions. More specifically, ingestion includes consumption of raw or under-cooked infected fish tissue, ingestion of fish tissue contaminated with feces from infected fish. Overall 46.15 % of fish-borne zoonoses are transmitted orally which are mostly helminthic diseases are caused by Trematodes, Cestodes and nematodes. Yet these zoonoses are responsible for large numbers of human infections around the world. Ingestion of water harboring infectious organisms with 23.07 % and Dermal exposure includes introduction of infectious agents into open wounds or abrasions through handling infected fish or infected water with 19.23 % are other transmission ways and importantly 15.38 % of fish-borne zoonoses are transmitted by more than one way. Distribution, epidemiology, clinical aspects, and the research needed for improved risk assessments, clinical management and prevention and control of these important diseases are reviewed.

        Listeriosis is one of the most important food-borne diseases caused by Listeria species, especially L. monocytogenes.&nbsp; The objective of this study was to determine the prevalence and antimicrobial resistance of Listeria species isolated from three types of fish filet in Isfahan and Bandaranzali. From August 2009 to April 2011, a total of 120 samples of Argyrosomus hololepidotus (n= 90), Scomberomorus commerson (n=80) and Alburnus spp (n=70). Fish were obtained from randomly selected retail stores in Isfahan and Bandaranzali cities and were evaluated for the presence of Listeria spp. using standard cultural and PCR methods. Then antibiogram tests were carried out for determination of antimicrobial resistance. Seven (8.8%) and 6 (15%) of smoked and salted fish samples were positive for Listeria spp. respectively. L. monocytogenes, L. innocua and L. seeligari were isolated from 2.5, 6.7 and 1.6% of fish samples. Overall, 9 of 13 Listeria isolates (69.2%) were resistant to one or more antimicrobial agents. Resistance to tetracycline (53.8%) and tetracycline (30.8%) were the most common finding. All of the isolates were susceptible to gentamicin, vancomycin and chloramphenicol.&nbsp;The results of this study indicate the potential risk of infection with Listeria in people consuming raw or undercooked smoked and salted fish. Also, the results obtained in this study indicated the need for appropriate surveillance and epidemiological monitoring strategy to control the development of resistance.&nbsp; Manuscript profile

        A high number of parasites can infect fish, and some can be transmitted to humans. Human or fish-eating mammals can be the main host of these parasites. Today, more than 40 species of fish-borne parasites have been identified, causing disease in humans. These parasites can be classified as protozoa, trematode, Cestoda, Nematoda and Acanthocephala. Infection in humans usually occurs following the consumption of larvae-infected meat. The possibility and the rate of infection directly relate to different criteria, including the fish consumption rate, level of hygiene, feeding habits, and methods of cooking or processing. In this article, having discussed the fish-borne parasites, the reports of zoonotic parasites from fish in Iran have been discussed. Manuscript profile

        The present study was performed to evaluate the occurrence and pattern of antibiotic resistance of Enterococcus faecalis strains isolated from fish and shrimp samples caught from the Persian Gulf. A total of 240 seafood samples caught from the Persian Gulf, including 120 fish and 120 shrimp samples were collected from Bushehr province. The presence of E. faecalis was confirmed using microbial culture and biochemical tests. The pattern of antibiotic resistance of E. faecalis isolates was evaluated using Disc Diffusion Method. Fifty-four out of 240 (22.50%) samples were contaminated with E. faecalis. The contamination of E. faecalis in fish and shrimp samples were 30% and 15 percent, respectively. E. faecalis strains isolated from fish and shrimp samples had the highest resistance to gentamicin (100%), tetracycline (100%), erythromycin (100%), cefazolin (90.74%) and trimethoprim-sulfamethoxazole (88.88%) antibiotics. Resistance to chloramphenicol was not observed in any of the isolates. The results of the study showed that fish and shrimp can be considered as possible sources of antibiotic-resistant E. faecalis. Therefore, complete cooking of seafood before consumption, observance of hygiene in fishing and sale centers and prescribing antibiotics according to the results of the disk diffusion test can prevent gastrointestinal infections caused by antibiotic-resistant strains of E. faecalis.

        Anisakiasis is a zoonotic disease caused by the nematode Anisakis caused by eating infected and uncooked fish. Due to the fact that this disease is zoonotic, the necessary health advice should be given to people who tend to eat raw and especially raw foods of different types of seafood. Based on the search results with the keywords, Iran and Anisakis in information sources and search engines, 24 studies conducted in Iran on Anisakiasis disease were found. This parasite has been reported in Iran to a greater extent than the shores of the Caspian Sea, Persian Gulf and Oman since 1349, which according to the results obtained in regular reviews, this amount has been higher in the southern regions of the country (Persian Gulf and Oman). Due to the high percentage of contamination in some of the fish studied, up to 97% of the need to pay attention to this parasite for food preparation is more evident. Manuscript profile

        Background &amp; Aim: Fish, having a vast role in providing sufficient protein for most humans across the globe, requires strict standards and quality assurance. Disease prevalence in fish farms has been an obstacle considered by many farmers. Various synthetic therapeutics such as antibiotics and chemical substances exist vastly in the market and are constantly used for disease prevention. Nevertheless, chemicals come along with a set of drawbacks putting both fish and human health in danger.Experimental: In this study, we discussed and reviewed the chemical composition as well as the benefits of Echinacea as a natural growth promoter and an immunostimulant in aquaculture. We reviewed 31 different studies conducted on a variety of fish. Biological activities, following the administration of different levels of Echinacea, were discussed as well.Results: A variety of functions had been reported for Echinacea species. These properties were classified into growth increase, disease resistance, antioxidant and immunostimulating effects, along with the promotion of blood biochemical parameters.Recommended applications/ industries: Based on the reviewed literature, Echinacea could improve growth and immunity in cultured fish. Using natural compounds instead of chemicals could substantially help create sustainable aquaculture. Manuscript profile

        Background &amp; Aim: Centella asiatica is considered a nutraceutical and its leaves are rich in carotenoids, vitamins B and C, amino acids, carbohydrates, phenols and terpenoids. The objective of this study was to investigate the effect of dietary supplementation of C. asiatica leaf powder (CP) on the growth performance of Labeo rohita.Experimental: Centella asiatica leaf powder supplemented feeds in 2 doses (1 g and 5 g) were prepared by mixing the CP in 5 mL vegetable oil, and then admixed with 1 kg each of basal pellet feed and fed to fish for 30 days at 3% body weight twice daily. The parameters like specific growth rate (SGR), feed conversion ratio (FCR) and protein efficiency ratio (PER), serum glucose and creatinine, and the respiratory oxidative burst (ROB) activity were tested.Results: The results of the growth indices, serum biomarkers and ROB activities indicated that the CP supplementation at 1 g/kg feed was reasonably the best as it gave the higher SGR, PER and ROB activity and lower FCR. The fish fed 5 g CP/kg feed negatively affected the growth in days 30 of feeding.Recommended applications/industries: Dietary supplementation of CP at 1g/kg feed provided a positive effect on the growth of L. rohita. No significant negative effects on the serum biomarkers of stress and kidney function were noted when fed at this level. Further studies are warranted to establish adequate doses of active novel molecules for dietary supplementation rather than using the dried powder. Manuscript profile

        این مطالعه به منظور بررسی اثر جلبک قهوه&shy;ای دریایی و ویتامین E بر ماندگاری گوشت مرغ غنی شده با روغن ماهی انجام شد. در این آزمایش 360 قطعه جوجه گوشتی یکروزه (آربوراکرز پلاس) که به صورت تصادفی در 6 تیمار با 4 تکرار شامل 15 جوجه اختصاص داده شدند. گروه‌های آزمایشی شامل: گروه مصرف کننده جیره پایه (ذرت و سویا)، جیره پایه به همراه روغن ماهی، جیره پایه به همراه ویتامین E، جیره پایه به همراه روغن ماهی و ویتامین E، جیره پایه به همراه روغن ماهی و 5 درصد جلبک دریایی خشک شده و جیره پایه به همراه روغن ماهی و 10 درصد جلبک دریایی خشک شده بودند. روغن ماهی و ویتامینE &nbsp;در 2 هفته آخر پرورش استفاده شد. جوجه‌ها در روز 42 کشتار شده و نمونه‌های گوشت تهیه شده در دمای 4 درجه سانتی‌ گراد نگهداری شدند. میزان مالون‌&shy;دی‌آلدهید موجود در نمونه‌ها در روز‌های 0، 3 و 6 بعد از کشتار اندازه‌گیری شد. نتایج نشان داد که روغن ماهی باعث افزایش پراکسیداسیون گوشت شده و گذشت زمان باعث افزایش شدت آن می‌شود. تیمار‌های دریافت کننده ویتامین E پایین‌ترین میزان مالون‌&shy;دی‌آلدهید را نشان داند و همچنین باعث افزایش ماندگاری گوشت&shy;های غنی شده با روغن ماهی شدند. مصرف 10 درصد جلبک دریایی ماندگاری گوشت نواحی سینه و ران را در روز‌های 3 و 6 بعد از کشتار افزایش داد. بررسی پروفیل اسیدهای چرب نشان داد که استفاده از روغن ماهی باعث انباشت معنی‌ دار اسید چرب امگا 3 در عضله‌های ران و سینه می‌شود. همچنین مصرف همزمان روغن ماهی با جلبک دریایی باعث افزایش انباشت امگا 3 در عضله ران شد. ازطرفی مصرف جلبک دریایی سبب کاهش معنی دار میزان کلسترول و تری&shy;گلیسیرید سرم خون جوجه&shy;ها شد. به صورت کلی مصرف ویتامین E و جلبک قهوه‌ای دریایی باعث افزایش ماندگاری گوشت‌های غنی شده با امگا 3 شد.

        این آزمایش در جوجه‌های گوشتی به منظور بررسی اثرات اسید لینولئیک کنژوگه (CLA)، روغن ماهی در سطح 7 درصد و یا مخلوط 5/3 درصد از هریک از آنها در جیره غذایی، بر صفات تولیدی و لاشه و همچنین ریخت شناسی روده جوجه‌های گوشتی انجام گرفت. جوجه‌های تغذیه شده با جیره‌های حاوی 7 درصد روغن ماهی یا 7 درصد CLA اثر نامطلوبی بر افزایش وزن در فازهای رشد و پایانی داشتند. کاهشی معنی دار در مصرف خوراک در مورد جیره‌های حاوی 7 درصد روغن ماهی مشاهده شد. با این حال، افزودن CLA به جیره‌ها اثری بر مصرف خوراک در پرنده‌ها نداشت. مکمل‌سازی روغن ماهی و CLA در جیره به طور نامطلوبی ضریب تبدیل غذایی و نیز صفات لاشه را تحت تأثیر قرار داد. CLA در سطح 7 درصد باعث افزایش وزن کبد شد. تفاوتی در درصد لاشه، ران یا چربی حفره بطنی بین تیمارهای آزمایشی دیده نشد، با این جود، پرنده‌های تغذیه شده با جیره حاوی 7 درصد روغن ماهی دارای کمترین درصد سینه و بالاتری درصد کبد بودند. ارزیابی بافت شناسی روده کوچک مشخص نمود که جیره حاوی 5/3 درصد روغن ماهی + 5/3 درصد CLA باعث بالاترین ارتفاع ویلی در مقایسه با جیره‌های حاوی 7 درصد روغن ماهی یا CLA شد. چنین افزایشی در عمق کریپت دودنوم و ژژنوم مشاهده گردید، اما تفاوتی در عمق کریپت ایلئوم دیده نشد. ضخامت دیواره روه کوچک و تعداد سلول گابلت در جوجه‌های تغذیه شده با جیره حاوی مخلوط روغن ماهی و CLA پایین‌تر از سایر تیمارها بود. نتایج این تحقیق نشان داد که یک دز بالا از روغن ماهی یا CLA می‌تواند بازدهی تولیدی جوجه‌های گوشتی را کاهش دهد، اما ترکیب آنها می‌تواند این اثر مضر را تعدیل نماید Manuscript profile

        600 جوجه گوشتی تعیین جنسیت نشده یک روزه در یک آزمایش 35 روزه برای مقایسه اثرات روغن سویا، روغن نخل و روغن ماهی بر عملکرد جوجه‌های گوشتی شامل مصرف خوراک، افزایش وزن و ضریب تبدیل غذایی استفاده شد. جوجه‌ها به طور تصادفی در قالب طرح کاملاً تصادفی در چهار گروه با سه تکرار در هر تیمار توزیع شدند. در هر تیمار 150 و در هر تکرار 50 پرنده قرار داده شدند. چهار جیره غذایی با استفاده از مواد خوراکی در دسترس فرموله شد که شامل جیره غذایی بدون روغن، جیره غذایی حاوی 3/0 درصد روغن سویا، 3/0 درصد روغن نخل و 3/0 درصد روغن ماهی بودند. نتایج نشان داد که افزودن انواع مختلف روغن بر مصرف خوراک جوجه‌های گوشتی تا هفته 2 تأثیر نمی‌گذارد (05/0P&gt;) اما در 3، 4 و 5 هفته افزایش می‌یابد (05/0P&lt;). افزایش وزن زنده جوجه در میان گروه‌ها تا سن 3 هفته متفاوت نبود (05/0P&gt;) البته در هفته 4 تفاوت داشت. بالاترین افزایش وزن زنده در هفته 4 در 3/0 درصد روغن ماهی گروه مشاهده شد. گروه روغن نخل حداقل تبدیل غذایی را نشان داد که فقط از گروه روغن ماهی متفاوت بود. هزینه خوراک در جوجه‌های گوشتی که روغن ماهی دریافت نمودند بیشتر از گروه بدون روغن، روغن نخل و روغن سویا بود. کل هزینه برای جوجه‌های گوشتی نیز در میان گروه‌های متفاوت بود (01/0P&lt;). سود خالص بیان شده به دلار به ازای هر کیلوگرم وزن زنده جوجه بین تیمارها متفاوت نبود (05/0P&gt;). حداکثر سود خالص از پرندگان تغذیه شده با جیره غذایی حاوی روغن نخل و حداقل از جوجه‌های گوشتی تغذیه شده با جیره غذایی حاوی روغن سویا بدست آمد. نتیجه‌گیری می‌شود که افزودن روغن ماهی در سطح 3/0 درصد سبب افزایش کمی در وزن زنده و خوراک تبدیل بیش از گروهی که از همان سطح از روغن سویا و نخل دریافت نمودند، می‌شود. با این حال، سود خالص و همچنین قیمت هر کیلوگرم گوشت مرغ زنده در مکمل روغن نخل نسبتاً بالاتر از روغن سویا و روغن ماهی بود.

        There are currently several methods to prevent scouring the bridge base. These methods can be divided into two general categories. The first group is to increase the strength of the substrate materials against erosion, such as the use of a gobion, a rap ramp around the bridges, and the second one, by changing the pattern of the flow around the bases, reduces the strength of the erosion factors, which are the collars, And bridge bridges are examples of these methods. In this research, the experimental study of the impact of the bridge nose bridge on the scour depth reduction was considered. For this purpose, 22 experiments were carried out in the vicinity of the pollen and triangular nests at four angles (0.70,75,80.90) 215/0, 232/0, 261/0). According to the results of the experiment, the reduction of scour depth in the triangular nose support for different floats in all angles had the best performance in reducing the scour depth during the experiments.

        The study involved 643 fish value chain actors in Niger and Kebbi States in Nigeria from whom data were collected between April 2022 and February 2023 via structured questionnaire and analysed using Garrett ranking, Structural Equation Modelling (SEM) and regression. These two states have access to Rivers Niger, Shiroro and Kaduna and their various tributaries. From the results obtained, 48 variables out of the 65 described by the actors were considered a constraint based on the mean and five latent factors were determined and the values retrieved for further analysis. The latent variables exhibited positive bi-directional relationship between one another which is an indication that the factors are not isolated occurrences. From the propensity score matching (PSM) and regression, a number of policy variables were obtained which may call for further investigation but needs to be adequately addressed. Particularly, the tendency of low probability of participation in the face of low educational acquisition. There is also a very strong indication that the actors are conducting their businesses with low capital which has further devalue the level of participation. Ultimately, doing business with adequate capital can increase participation by up to 15% and as such, can increase outputs, income, profits and enhance livelihoods. Manuscript profile

        The objective of this study is to determine factors affecting the technical efficiency of the inshore fisheries in Kuala Terengganu. Data for the study was collected from a survey conducted between June and August 2007 where 100 fishermen in 14 villages were chosen by stratified sampling. Data envelopment analysis (DEA) and Tobit analysis were employed to determine the technical efficiency level and factors influencing technical efficiency among the fishermen. Results of the study show that, most fishing units exhibit a low degree of technical efficiency. This implies that either fishing inputs were used inefficiently or insufficient inputs were used in fishing activities. The mean technical efficiency for the sample was estimated to be 55% for the peak season and 40% for the non-peak season. About 37% and 62% of the fishermen had less than 40% level of technical efficiency in peak season and non-peak season respectively. Management variables (planning, staffing and controlling) and demographic variables (size of horsepower, size of family and formal education) exert positive effects on technical efficiency of inshore fisheries in Kuala Terengganu. These findings suggest that there is much room for improvement in efficiency among a large segment of the inshore fishermen. With appropriate training and using more advanced technologies, fishermen&rsquo; level of technical efficiency can be raised. Manuscript profile

        The bias against mangrove areas in siting fish farms prompted a comparison of the cost structure and yield performance in upland and mangrove locations. Tools utilized included descriptive statistics, budgetary and cash flow analyses and profitability ratios. Empirical results revealed that substantial revenue could be realized from both farms. While the upland farms yielded average gross revenue per hectare per year of $9, 183.53, the mangrove farms made $8, 135.93 revealing a slight difference. Results of combined cash flow and sensitivity analysis buttressed that of budgetary analysis. NPVs were $10, 888.11 and $10, 375.84, B/Cs was 1.28 and 1.29 and IRR were 48.55% and 48.51% for the upland and mangrove farms, respectively. Profitability ratios were also comparable but slightly higher in the upland farms. The conclusion is that there was little or no difference in yield performance. However, the high risk of investment loss in years of excessive flood should prompt investors in mangrove farms to compulsorily insure their farms. Manuscript profile

        Gender determination in the fisheries industry is important for the propagation and cultivation of economically valuable fish. In fish meat, due to the extraction of caviar, the proper method of gender determination is essential. This research was conducted in 1396 on Huso huso, in a closed circuit system, at the Hanusushadeh sturgeon farm, in Khuzestan province. To determine the gender, the fish were first anesthetized in a tub with 100 ppm of eugenol. They were then weighed using a digital scale, with a precision of one gram. In this research, gender determination of all fish was carried out with 100% accuracy. The ultrasound method was used to determine the gender by the Zoncer ultrasound apparatus in Germany. In this research, all fish with 100% accuracy were sexually explicit. Of the 1,000 pieces of Huso huso, 516 male and 484 female pieces were studied. Male and female fish had a weight range of 5150-4236 grams and 7125-4896 grams, respectively, and were 3 years old. Given that gender evaluation on all fish was carried out using ultrasound, this method can be considered the best and most reliable method for determining the gender of sturgeon, as the use of methods which cause the least stress in fish is always a priority.

        Cormac McCarthy's The Road, with its ashen, post-apocalyptic landscape, seems a conspicuous exodus from the realism of his earlier novels. Its horrendous atmosphere frustrates the readers and forces them to ask: what really has happened to the world? And is there any kind of salvation for modern man after the horrific post-apocalyptic era? In this novel McCarthy portrays some events which he thinks they are the impossible fate of human beings. He narrates a journey of a father and a son who try to survive after the civilization has been wiped off the face of the earth. The present study has analytic-comparative approach and its main objective is to prove that there is a close relationship between the postmodern novel of The Road and ancient myths of The Holy Grail and The Fisher King. In this research the emphasis is not on the characteristics of The Road as a postmodern novel, but on the myths which are older and more significant. In the post-apocalyptic world which everything is ruined, the only remedy of human being is seeking transcendentalism through myths. The world created upon individual benefit and expediency is doomed. The result of this research reveals that the only salvation for man is to build new moral principles regardless of individual benefit. In fact, the antidote which can cure this melancholic world is nothing but to have mercy upon others; in other words, for survival we need to have compassion and love for others without any condition or calculation.

        The effect of oral green skin of walnuts on the coloration of Oscar fish (Astronotus ocellatus) was studied. Albino Oscar fish with an average weight of 60 grams 5/01 ± 0/18 and 54/84 ± 2/23 mm average length in the form of 3 experimental and one control and each with three repetitions were divided. Twelve aquariums with dimensions of 50 × 40 × 33 cm was used. Control was fed with no food additives (food stand). For the first treatment food containing 0.1 percent walnut hull was used, 0.2 percent was used for the second treatment with the diet and in the third treatment fish were fed with food containing 0.3 percent walnut hull. The breeding period lasted 8 weeks (56 days). Every 20 days biometrics (Biometry) was carried out. Average water temperature in the aquarium during the study period was 28.07 ± 1.09 °C, with an average of 5.38 ± 0.15 milligrams per liter of dissolved oxygen, average pH was measured to be 8.03 ± 0.33 and average TDS,  33.27 ± 1.32 mg. After the breeding period, 3 fish from each treatment were randomly selected to assess the rate of change of color obtained using L* a* b* colorimetric system using a CHROMA METER CR-40. Colorimetric analysis of fish skin from treatments showed that oral administration of green walnut caused significant skin discoloration. Component b* ​​representing the yellow color, was positive in the treatment 1, showed significant differencecompared to control (P0/05). The results showed that using the green skin of walnuts in the diet can increase the Oscar fish skin color towards yellow. It was shown that the level of 0.1 percent green skin of walnuts in the diet was the best level for increasing  the yellow color in fish were detected. Manuscript profile

After weighing, the raw paste was prepared along with other additives, according to the general method of burger production &lrm;from meat. Chemical and biological tests were based on the method recommended by Iranian National Standards Organization.&lrm; The results showed that with increasing storage time, TVB-N and peroxide were significantly increased in silver carp burgers, in cold storage,. The mean (&plusmn;SD) of TVB-N of fish burger changed from 12.6&plusmn;0.14 mg% at the time of production to 14.4&plusmn;0.14 mg% and the peroxide changed from zero to 1.33&plusmn;0.14 meq of oxygen at the end of three months of storage. Total count of mesophilic bacteria, coliform and staphylococcus aurous were lower in fish burgers compared to meat burger products, and for both treatments statistically significant difference was observed for the mean total count of mesophilic bacteria in the first month and for coliform, Staphylococcus aurous bacteria in the second month(p&lt;0.05). Salmonella and E.coli were not observed in any of the treatments and at the end of the storage period they were in accordance with the standards recommended by Iranian National Standards Organization. Therefore, it can be concluded that fish burgers have longer cold storage period compared to burgers produced from red meat. Manuscript profile

        In this study the effect of oral administration of green skin of walnuts on the growth and color of Koi fish (Cyprinus carpio) has been studied in 60 Koi fishof average weight of 1.50&plusmn;0.06g and average length of 53.00&plusmn;1.48mm in 3 treatments and 1 control and each with 3 replicates.Twelve aquariumsof 33&times;40&times;50 dimension were used. The control group had no food additives (basic food was fed). First treatment with food containing 0.1 percent, second treatment with food containing 0.2 per cent, third treatment with food containing 0.3 percent green skin of walnut was fed for 8 weeks (56day) breeding period. Every 20 days once, biometry including gravimetric and length measurement was done. Also, at the end of the period from each treatment, 3 fish were selected at to random.To asses the color change, the colorimetric system L*a*b* was used, using device CHROMA METER CR_40. There was no significant difference regarding all three factors. Generally, it can be concluded that the use of green skin of walnuts to fish food ration, cause no impact on some growth factors and as well as survival rate and food conversion rate, but the apparent color index impact was significanot(P&ge;0.05) Manuscript profile

        The aim of this study was to determine the importance of gammarid (Pontogammarus maeoticus) in the diet of larval bony fishes, in the Caspian Sea. Sampling of coastal gammarus and larvae was conducted in two phases (December 1389 and April 1390), from 12 stations (in four districts, each with 3 stations) in this study. Fish were caught at 0.5 to 1 meter depth, using a mesh cloth (the aperture diameter of one millimeter) of 0.5 &times; 1 meter dimension and were immediately fixed with 70 % alcohol and transported to the laboratory. Gammarus were caught from the coast sand using a handmade rectangular fishing net of one mm diameter aperture and 40&times;60 cm dimension. In the winter of 1389, 98 fish and in the spring of 1390, 107 species of fish were sampled. The sampled specimens included Liza saliens, Rutilus frisi kutum, Atherina boyeri, Benthophilus ctenolepidus, Gasterosteus aculeatus with the weight range of 0.45 &ndash; 3.25, 0.6 &ndash; 3.27, 0.81 - 5.88, 1.17 &ndash; 3.67 and 1.27 &ndash; 1.96 gram, respectively. In order to identify the fish species which are consumers of gamarids, gastro intestinal contents were analysed. The results showed that species collected have different amounts of coastal gammarus nourishment. In winter the highest amount with an average of 8.25 percent in 1389, related to Rutilus frisii kutum and in the spring of 1390 with an average of 1.92 percent related to Liza saliens.

        The aim of this study was to investigate the effect of fish displacement using fishing net and fish pump on the apparent characteristics and blood factors of Sparus aurata fishes in Tiyab Pran Qeshm workshop. The statistical population consisted of 1500 fish with an average weight of 10 g. In the control group, fish were kept calm and were not subjected to any tension and pressure. The second group consisted of a treatment in which the displacement was carried out using fishing net and the third group was the treatment in which a fish pump was used for transferring the fish. Regarding the hematological parameters, the highest number of red blood cells (1.49) and white blood cells (46.91) in cubic millimeters were recorded in fish samples displaced using the fish pump. Similarly, the maximum amount of lactate (58.66) and cortisol (1.32) in ng / ml, glucose (64.01 mg / dl) and chlorine (130.55 &mu;m) were obtained in the treatment using the fish pump. The results of the study showed that the tensions that were introduced to the fish while using the fish pump were more compared with the treatment using fishing net (p &lt;0.05). However, the use of the fish pump caused less mechanical damage and less fish mortality, and more fish could be displaced using this method and during transfer fish did not suffer from lack of oxygen, as they were in the water during the transfer, and received enough oxygen. Therefore, displacement of fish with a fish pump, taking into account the necessary measures to reduce stress, can be considered as reliable methods for transferring more fish from acceptable mechanical damage.

        In this research bacteriological and protein changes of Rutilus frisii kutum (kamensky) that caught off from caspian sea in two storage temprature at (-18C) and (4C) were evaluated. Sample were divided in2 studied groups, at first, 13 fish (Rutilus frisii kutum) were collected in coast of Noshahr. In the first group seven fishes were storied at (4C) and tested in: 1st, 3th, 6th, 9th, 12th, 15th, and 18th, days. In the second group we had six fishes which storied in (-18C) and test in 1st, 3th, 45th, 90th, 135th, 180thdays. In fishes which stored at (4C), the indicator of chemical spoilage (Total Volatile Base-Nitrogen) reach to maximum consumption limit 32mg/100 and aerobic bacteria population in the day of 15th passed from maximum limit(1/7&times;107cfu/g) fishes whiches stored at (-18C), in the day of 180th ,the indicator of chemical spoilage (TVB-N) reach to maximum consumption limit 30mg/100, but microbial population was in acceptable limit. It seems low temperature has direct influence to reduce rate of spoilage and also TVB-Nwhich is the base the best indicator for quality control of fish in storage period than microbial indicators in cold and freezing Storage condition.

        The annual global growth rate of the human population (estimated for 1/3%) is enhancing the demand for provision of individual animal protein to one-third from 70 g daily dietary protein intake. An increasing interest in fish food consumption because of its health benefits has made seafood products to play an essential role in food basket of Iranian family as like as other parts around the world. Aquaculture growth in Iran and throughout the world has provided a suitable condition to supply nutrition safety for this valuable food source. Now, from a total amount of 78.4 g daily dietary protein intake per capita, 30.7 g is supplied by animal protein from which 5 g is comprised of fish protein. Results obtained during the last half a century indicates that fish consumption growth in Iran has been far more than other parts in the world; however, its consumption rate per capita is much lower. It is noteworthy that fish food consumption growth was higher rather than chicken and red meat consumption growth according to the base year 1965, as Fish per capita consumption can be elevated by different accessibility methods and controlling price and quality.

        Fish is one of the most significant and valuable food resources that plays an important role in nutraceutical foods and is the most important source of polyunsaturated fatty acids (PUFA), in particular n-3 fatty acids. Increasing fish consumption is the only realistic way to increase the beneficial&nbsp;PUFAs and to create more favorable W-6: W-3&nbsp;in the human food diet. The objective of this project was to determine the fatty acid composition of the muscle tissue of three species of brackish water fish, carp fish, white fish and beluga. In all three types of fish, oleic acid (C18:1c) concentration was the highest. The highest levels of PUFA found in beluga and white fish was linoleic acid (C18:2c) and in carp fish, docosahexaenoic acid (C22:6).&nbsp;&nbsp; The results showed that the saturated fatty acid in the studied species were&nbsp;47, 50.2, 24.45&nbsp;percent respectively. The results for PUFAwas 8.9, 15.9, and 40.73&nbsp;percent and finally for MUFA were 45.6, 34.4, and 34.9 percent of total fatty acids, respectively. The W6:W3 ratio in these fish species was&nbsp;0.64, 0.74, and 2.99 respectively. The total amount of fatty acids was analyzed using GC/MS and results were statistically analyzed using analysis of variance method (one - way ANOVA). No significant difference was observed among three studied species of fish (P&gt;0.05). In all three species the unsaturated fatty acid levels were higher than the saturated fatty acid levels and according to their W6:W3 ratio, all three species are considered to be valuable sources of nutrition.&nbsp; Manuscript profile

        Nutritional needs are important in successful breeding process of the fishes. Aloe vera gel having beneficial compounds such as the eight essential amino acids, monosaccharides and polysaccharides, vitamins C, B12, B6, B2, B1, A, E and minerals, can be used as a valuable supplement and food rations used in natural aquatic environment. Effect of prescription of this crude extract of plant Aloe vera in Oscar (Astronotus ocellatus) with an average weight of 17.57 &plusmn;2.56&nbsp; g were studied in this research. Therefore, 54 fish in three treatments, each with 3 repeats were used in this research. Two treatments included a concentration of 2 and 5% crude extract of Aloe vera plant which were added to the Biomar feed size of 0.8 mm used for Carnivore fishes. Samples were fed for 60 days with the fortified feed. The control sample feed were not fortified. The results indicated that feed fortification with plant extracts of Aloe vera makes a significant difference (p&lt;0.05) in weight gain, growth factor and coefficient of obesity and reduced food conversion factor compared with controls, and increase in fortification showed an increased effect. No mortality was observed in both treatments. Fortified feed at 5% showed a better result as a whole. Manuscript profile

        This study aims to investigate the effect of vitamin C with in the diet plan of Cyprinus carpio (Koi fish) will result in positive outcomes on the survival, growth performance and hematological parameters of these particular breeds.&nbsp; The purpose of this paper was to increase the production performance of ornamental fish species in the aquaculture with the aim to keep the time and costs to a minimum. In order to achieve these results, the author framed an experiment on 144 Koi fishes in four different groups (one control group and three treatment groups). Later on, all the four groups were fed with vitamin C rich diet (with the doze of, 200, 400, 600 mg per kg of dried ration) for two month.&nbsp; The biometric juveniles (total length and standard weight) of the subjects were measured every 14 days. Moreover, the calculation of growth rate, hematological rates and feeding the subjects were performed at the end of a two month time period. Results showed that addition of vitamin C in diets caused an increase in weight, in control group, whose diets were without vitamin C became in average 1.58 g, treatment 1 in average 1.73 g, treatment 2 in average 2.13 g and treatment 3 in average 4.4 g and increasing weight among groups had significant differences. Survival rates in control group was in average 84%, in treatment 1, 95%, in treatment 2, 95% and in treatment 3 was 97%, &nbsp;but there were no significant differences among groups. In studied fish we faced with increasing percentage of body weight of 39.71% in treatment 3 which has no significant differences with other groups. The most growth rate was assessed in treatment 3 (0.58) and it had significant difference with the control group only. Protein Efficiency Ratio in treatment 3 was in average 2g and it had no significant difference with other groups. There were no significant differences among these groups in number of white blood cells and the most number of white blood cells was assessed in control group.The number of lymphocytes were increased by the increase in the amount of vitamin C and the highest amount was reached in treatment 3, which was 70, but there was no significant difference in number of lymphocytes among groups. Finally based on results in present research, vitamin C with concentration of 600mg in kg in dry diets is recommended for increasing growth performance and hematological parameters in Koi fish.

        In this study, the concentration of histamine in caviar fish fillet, due to enzyme activities, was studied. The histamine concentration in fresh and smoked Stellate sturgeon and frozen Beluga fish was investigated. Maximum limit for histamine in raw fish muscle and cooked products such as canned fish, recommended by Codex are (200 &micro;g/g) and (50 &micro;g/g), respectively. Due to the higher levels of histamine in frozen Beluga fish fillet (157.7&plusmn; 16.89 &micro;g/g) relative to fresh (5.84&plusmn;2.79 &mu;g/g) and smoked (20.52&plusmn;4.20 &mu;g/g) Stellate sturgeon fish, in this study the frozen Beluga fish fillet was selected for further investigations. Analysis of histamine in the defrosted Beluga fish fillet was carried out using high performance liquid chromatography, just after thawing (0), 12 and 24 hours after storing in the refrigerator. Statistical analysis (ANOVA) was performed on the results using SPSS version 11 software, to evaluate the significance of storage period in the refrigerator, on the production of histamine. They were also compared with Codex recommended levels using t test. The results showed that the concentration of histamine differed in different types of caviar fish fillets. They also showed the significance of time in the production of histamine. However histamine levels were significantly lower than the codex recommended maximum limits in all analyzed samples, except for the samples kept in the refrigerator for 24 hours, which were close to the recommended limit and no significant difference was noticed between their level (228.1&plusmn;19.73 &micro;g/g) and the recommended limit.

        The aim of this study was to determine the accumulation of heavy metals (nickel, mercury and cadmium) in muscle and skin tissue of Tanoalosa ilisha in Khuzestan province (Karun River, Arvand Rud River, Bahrakan). For this purpose, after determining the stations by GPS, sampling of the Tanoalosa ilisha fish was performed using a fishing trip. After catching fish randomly, fish were placed in contact with ice in standard conditions and quickly transferred to the laboratory. Subsequently, the samples were evaluated for measuring the factors of this study based on international standard methods. The results of this experiment showed that the highest concentrations of heavy metals evaluated in this research (nickel, cadmium and mercury) were at the Bahrakan station and the lowest concentration of metals were in the Arvand Rud station. Generally, the concentration of nickel metal found in the fish muscle in Karun was 1&plusmn;162.11 ???and Arvandroud&nbsp; Rud station, 0.0&plusmn;908.09, was higher than the FDA limit. However, nickel in the Tanoalosa ilisha fish skin was higher than the permissible level in all three stations, 1&plusmn;901.219, 1&plusmn;588.22. 1&plusmn;222.15. Regarding cadmium levels in muscle tissue at the Bahrekan and Karun stations, 0.0&plusmn;547.08, 0.0&plusmn;421.05, were higher than the WHO and below the FDA recommendations, but at Arvand river the levels were lower than WHO and FDA limits. However, the cadmium content of the endangered fish of all three stations, 0.0&plusmn;648.106, 0.0&plusmn;494.07, 0.0&plusmn;340.09 was higher than the WHO standard and was below the FDA standard. The accumulation of mercury metal in skin tissue and Tanoalosa ilisha fish muscle in all three stations was lower than the FDA and FAO limits.

        This study was carried out for determining beach seine effects on the macroinvertebrate communities in Shohadaye Anzali -Shirin Mahale andestuaries of Polrud River study areas. In order to survey the effects of beach seine, samplings were carried out in selected stations during the beach seine fishery season (October- March) and when no beach seine fishery was performed (June-September). Hence, four stations in Shohadaye Anzali - Shirin Mahale and three stations in Polrud River estuaries were chosen for sampling. Statistical analysis of data, normalization, correlation, mean comparison for different parameter used, was performed by applying Kolmogorov&ndash;Smirnov test (K&ndash;S test) and Pearson's Correlation Coefficient, respectively. One-way ANOVA for comparison of means of each parameter, between stations, was used. Classifications of homogeneity of the groups of different benthic organisms throughout the stations were analyzed by Tukey&rsquo;s test. The results of this study showed that there were significant differences in frequency and biomass of the macroinvertebrate species, during the the beach seine fishery season and after the closing of beach seine fishery (p&lt; 0.05). The results also showed that there were no significant differences in species diversity index (p &gt; 0.05). Manuscript profile

Fish sampling was done by cast net during summer, autumn and winter 2007 and spring 2008. The results showed that the mean concentrations of lead and cadmium was 181.6 and 91.03 in Cyprinus carpio, 191.07 and 88.13 in Carassius auratus gibelio, 145.7 and 70.85 in Alburnus alburnus and 117.92 and 60.68 &micro;g/kg in Capoeta aculeata. The mean concentrations of lead and cadmium in total samples were 159.02 and 78.09 &micro;g/kg, respectively. The mean concentration of cadmium in samples examined exceeded acceptable threshold established in the European Commission (EC). Lead and cadmium concentration in 10% and 57.5% of samples exceeded the tolerance limits established in EC respectively. The results showed that there is significant difference between cadmium levels in meat of fish species (P&lt;0.05). The high concentration of cadmium and lead in fish meat is probably due to missusing of phosphate fertilizers in agriculture affairs and entry of agricultural sewage into the river.&nbsp; Ninety meat samples of fishes caught from BeheshtabadRiver including Cyprinus carpio (n=29), Carassius auratus gibelio (n=15), Alburnus alburnus (n=27) and Capoeta aculeata (n=19) collected and used for determination of lead and cadmium with the graphite furnace atomic absorption spectrometry after wet digestion.

        The increased industrial applications of nanoparticles increase the possibility their deposition into aquatic ecosystems and thereby threatening the aquatic life. Therefore, this study aimed to provide the toxicological effects of ZnO NPs (0, 1,2,4,8 mg.L-1) on certain hematological indices of Koi fish for a period of&nbsp; 2 and 10 days, under static bioassay. A significant decrease in hemoglobin (Hb) content 7.3&plusmn;0.19, red blood cell (RBC) count 1.41&plusmn;0.03, hematocrit (Hct) value 22&plusmn;0.66, mean cellular volume (MCV) 155.35&plusmn;5.29 and mean cellular hemoglobin (MCH) 51.2&plusmn;2.07 (except on 4 mg.L-1dose) was noticed throughout the study period of 10 days when compared to control groups. In contrast, mean cellular hemoglobin concentration (MCHC) levels 4&plusmn;0.23 were found to increase during the study period.Our results demonstrate that high ZnO NPs concentrations in the aquatic environment may have adverse effects and cause acute changes on hematological parameters of Koi fish.

        There are several factors affecting Angel Fish fry's (Pterophyllum scalare) survival and quality. In this study, the effect of temperature on weight, length and survival of Angel Fish fry has been studied. Three temperatures of 27, 29 and 31 degree of centigrade were considered with three repetitions. Thus 9 aquariums with 60 &times; 40 &times; 30 centimeter dimension were allocated for these treatments and dry Blood worm in addition to Artemia decapsulated cyst was used to feed aquariums in 30 days. Other factors such as food, pH and oxygen were similar for all treatments. The result of this search has showed that growth and survival of Angel fish fry in 31˚C had the best result and more growth and survival in comparison to the other observed temperature. Using the mean test between length and survival percentage, it became known that there is significant difference between the temperature treatments (P&lt;0.05) and for weight there is significant difference at 27 degree of centigrade in comparison to the treatment of 29 and 31 degree of centigrade, but there is no significant difference at 29 degree of centigrade in comparison to the treatment of 31 degree of centigrade (P&gt;0.05).&nbsp; Manuscript profile

        Infectious diseases are major economic losses in fish production facilities. Aeromonas hydrophila&nbsp;is considered as an important pathogen causing primary infection in wounds or the secondary problem following stress raised from temperature changes, handling, or poor water quality. This study was aimed to isolate A. hydrophila&nbsp;from crayfish Astacus Leptodactylus and to determine its virulence genes. Ten infected crayfish were investigated in this descriptive study. Samples were cultivated on Brain Heart&nbsp;Infusion (BHI)&nbsp;Agar medium. Bacterial identification was performed using both biochemical and molecular tests. Also, the presence of three virulence genes (lipase, elastase, and aerolysin) was investigated in the isolates. Two&nbsp;A. hydrophila strains were isolated from 10 infected crayfish with symptoms including black plaque, abscess, soft shell, corrosion appendages, and lethargy. One of the isolated strains had lipase and elastase genes, and the other one contained lipase, elastase, and aerolysin virulence genes. Our results showed the presence of different virulence genes in different A. hydrophila&nbsp;strains isolated from infected crayfish. Further studies are required to clarify the role of these genes in pathogenicity and virulence-related symptoms in the aquatic species. Manuscript profile

        Field and Aims: One of the occupations that the International Labor Organization (ILO) has deal with, due to its importance and frequency, is fishing. Many countries have not yet particularly addressed the dimensions of this issue; such as the difficulty of working in this profession, low wages and various dangers that always threaten fishermen; and this has caused fishermen to experience a lot of discrimination compared to other jobs.Method: In this research, descriptive-analytical method has been used and librarymethod has been utilised as the method of collecting information.Finding and Conclusion: The International Labor Organization, as a leading organization for the protection of workers' rights, has codified and developed several laws to protect the rights of fishermen. The Convention (No. 188) and The Recommendation (No. 199) are among the most important documents of the International Labor Organization in the field of work in the fishing sector. The main purpose of these documents is to provide conditions so that fishermen can benefit from job security along with other workers and have the possibility of concluding fair work contracts, considering the difficulty of working at sea. Convention 188 provides a set of minimum requirements and standards. However, many countries are unable to fulfill these minimum requirements and standards. Providing technical and financial assistance is one of the main ways to help such countries. But it should always be kept in mind that the most important step to improve the rights of fishermen is to increase their awareness about their rights. Manuscript profile

        The aim of this study was to investigate the characteristics of the protein hydrolyzate from silver carp (Hypophthalmichthys molitrix) viscera using different percentages of Alcalase. For this purpose, hydrolyzed proteins were produced using different percentages of Alcalase and the samples were analyzed for the amount of total protein, moisture, fat, ash, soluble protein, hydrolisis degree, nitrogen recovery, amounts of minerals and color parameters (brightness, redness and yellowness). According to the results, increased the amounts of percentage of enzyme to substrate led to increase the amounts of moisture, fat, nitrogen recovery and red index and decrease the amounts of ash, brightness and yellowness index. In general, by increasing the percentage of Alcalase to the substrate, to a specified amount, that in this study was 1.5 percent, the degree of hydrolysis increased, but then, a further increase in the amount of the enzyme led to reduce the degree of hydrolysis and had negative effects on the other experiments.

        Effects of the probiotic bacteria, Pediococcus acidilactici on growth performance of the Convict Cichlid fish (Amatitlania nigrofasciata) were examined. The main aim of the research was to examine the related effects of the probiotic P. acidilactici to increase the production of ornamental fishes. 150 fries of the Convict Cichlid fish were fed for 60 day in 15 groups (1 control and 4 treatments, each with 3 replicants) with dry food containing the probiotic P. acidilactici (0, 0.5, 1, 1.5 and 2 gr/kg). Biometric features (standard length and body weight) were measured every two weeks and growth and feeding indices were conducted at the end of the period. Compared with the control group, the results showed better growth performance in the treatments and the best results achieved in the group 4 with 2 mg prebiotic per kg dry feed. The recent research proposed the use of the probiotic P. acidilactici to enhance ornamental fish production in hatcheries of the convict cichlid fish. Manuscript profile

In this study, scaled common carp (Cyprinus carpio) and scaleless sutchi (striped) catfish (Pangasius hypophthalmus) exposed to 0.1lethal concentrations of cadmiumto compare bioaccumulation of metalinliver, skin, gills, muscle and scales of both fishes. After preparationand chemical digestionof samples, tissue cadmium contentswereanalyzed by atomic absorption unit (Model Thermo). Incommon carp, the highest level of cadmium was found in the liver followed by the skin, gills and scales (538 , 98.3, 47.72, and 25.09 andmu;g/g.dw,respectively) and lowest was in the muscle (15.9 andmu;g/g.dw). In the catfish, the highest level of cadmium concentrated in the liver and then in the muscle and gill (195.5, 107, and 52.3 andmu;g/g.dw,respectively) and lowest was in skin (5.93 andmu;g/g.dw). The results of this investigation indicate that the carpand#39;s scaled armature, compared to the scaleless skin of the catfish,adsorbs metal toxicants leading to much lesser metals content in the muscle rendering this tissue rather safer for comestible consumption.

Studied stations were determined from up to down of the river, respectively: station 1 was in upside of the river nearness Samangan-e-sofla village, station 2 in Chehr bridge region and station 3 was in Sorkheh-deh region. In this project, to catch the samples only used from cast net with 1.5 cm meshes. According to the results of studying on the 486 fish speciments, 25 species of 5 families were identified: Minnows (Cyprinidae), River Loaches (Balitoridae), Catfishes (Sisoridae), Catfishes (Bagridae) and Spiny eels (Mastacembelidae) which had 20, 2, 1, 1 and 1 species in the studied region, respectively. Among identified families, Cyprinidae were the dominant fishes in whole of region and after that were Balitoridae. Also the results showed that the minimum caught species were in station 2 or near the source of polluting of the river and the maximum species found in station 3 or far from the source of pollution. In the other hand, industrial pollution and the waste of factories were effected on the dispersion of fishes and due to decrease the diversity of them and distance of the pollution due to increase the diversity of fishes.

To investigate the effects of Clomiphene on food ratio and growth factors in Gourami fish species (Trichogaster trichopterus) was done.  The Growth rate increasing was aimed for Achieving to more fish count in shorter time and less costs in the hatchery and fish farming. The numbers of 140 gourami fishes were fed for 2 month with dietary supplementation impregnated with different ratio of clomiphene (1, 1.5 and 2 mg/kg in dry diet), in 4 groups includes (a control group and 3 treatment groups). Fish biometric assay (total weight and standard length) were performed every two weeks and growth indices were calculated monthly. The results have shown that the use of clomiphene in the diet of growth factors (body weight increase, percentage of body weight increase, specific growth rate, protein efficiency ratio, average daily growth) was significant and positive effected, but food conversion factor was decreased significantly. Therefore, Clomiphene can be used as an additive and dietary supplementation in feed for Gourami fish Trichogaster trichopterus (3 spots gourami). Manuscript profile

        In this project, the effect of salvia officinalis extract coating in three treatments (at concentration of 1, 2, and 3%, respectively) was investigated on chemical and microbiological characteristics of fillets prepared from hypophthalmichthys molitrix during the 14-day refrigeration storage (4 &deg;C) period. On days 1, 4, 7, 10 and 14 of storage, the treatments were chemically analyzed in terms of thiobarbituric acid (TBA) and total volatile base nitrogen (TVB-N), microbial load (total bacterial load) and moisture content, acidity (PH), and water holding capacity (WHC). Based on the obtained results, the amount of TVB-N in all treatments was significantly reduced compared to control treatment (p &lt; 0.05). The increasing trend of bioaburic acid during storage period in all treatments was significantly lower than the control treatment. Considering total bacterial load, all of the coated specimens had significantly lower bacterial load compared to the control group except for the first day. Based on the evaluation results of treatments moisture during the storage period, there was a significant difference in all indices except on day 14. There was also no significant difference between samples with regard to samples WHC. Considering pH, a significant difference was observed in indices on different days between samples except on days 4 and 14. In relation to pressurized water, the obtained data from treatments showed no significant difference except on day 4. Considering that treatment 3 (treatment coated with 3% salvia extract) showed more advantages in most indices compared to other coated treatments, the above mentioned coating was therefore recognized as the best treatment in this study and its application is recommended for effective preservation of the chemical and microbial properties of food products during the storage period.

        The Persian Gulf and the Oman Sea are habitats for a variety of aquatic species, especially fish. Heavy metals are crucial pollutants in aquatic ecosystems and can be among the major factors influencing the health of consumers. The purpose of this essay is to conduct a systematic review of studies that have assessed the concentration of heavy metals in the muscle tissue of certain fish species in these waters, spanning from the year 2006 to 2018. This meta-analysis study was performed on 1182 muscle tissues of Pampus argenteus, Platycephalus indicus, Lutjanus johnii, javelin grunter, Johnius belangerii, Otolithes ruber, Scomberomorus commerson, Scomberomorus guttatus, Epinephelus coioides, caught from the Persian Gulf and the Oman Sea, in order to investigate the amount of these metals. Also, the safety of food intake and the comparison with the standards were investigated. The THQ and HI indices were found to be less than 1 in the all species of fish for adults, but for children only in Scomberomorus commerson in HI index is more than one. The amount of mercury, zinc and lead in the all pecies of fish, cadmium in Lutjanus johnii and javelin grunter and nickel in Scomberomorus guttatus and Epinephelus coioides were lower than all standards. The daily and weekly absorption rates for all studied metals were lower than the authorized JECFA Committee due to fish consumption. Also, the lowest amount of allowance for studied metals was found mercury in Scomberomorus commerson, lead in Johnius belangerii and cadmium in Platycephalus indicus. It seems that high use of the Platycephalus indicus in terms of the studied metals has led to health risks in children. Therefore, environmental protection, which it has been influential in creating nutritional health problems, is considered a necessity. Manuscript profile

This research was carried out in 2016 with the aim of evaluating the possibility of non-cancerous effects of heavy metals caused by the consumption of Barbus grypus fish in the city of Mahshahr in summer. In this research, samples of fish required from the daily fisherman's hunting in Mahshahr port were prepared in 2016. Sampling was done randomly from trapped and ready-made fish in the market, in which 26 samples were used. After biometrics, the muscle tissue of the samples was isolated and chemically digested. A ratio of density of cadmium, nickel, lead, chromium and zinc on the muscle was measured by atomic absorption device (Ultima2c) and based on information gathering; the risk ratio of heavy metals was determined by the questionnaire. The results of this study showed that the average concentration of cadmium and nickel, lead, chromium and zinc on fish Barbus grypus to arrange 2.848, 1.933, 23.3, 23.93 and 0.045 mg. dry weight, which was the amount of metallic cadmium, nickel, lead higher than the standard set by the world Organization like FAO, WHO, MAFF and FDA. According to the results of this study, the hazard ratio (HQ) of cadmium was higher than 1 (1.10), nickel lower than 1 (0.82), lead more than 1 (999.9), chromium less than 1 (0.019), and zinc more than 1 (10.25), according to which the consumption of Barbus grypus fish in this area would have a severe risk for consumers as a result of heavy metals.

        Heavy metals enter the environment by natural and human resources, and the rate of their entry into the environment is considerable. Water ecosystems are naturally the final recipient of the metals. This study aimed to determine the bioaccumulation of heavy metals (Cd, Cr, Ni, Zn, and Pb) in, Cyprinus carpio fish. The concentrations of heavy metals were measured using atomic absorption spectrophotometer method. Samples of C. carpio muscle in Dezful City, southern Iran were assessed. Overall, 200 C. carpio fish samples were selected and analyzed randomly. The mean concentrations of Cd, Cr, Ni, Zn and Pb were respectively 2.08, 0.2, 1.41, 39.95, 34.5 mg/ kg dry weight. The amount of Cd, Ni, Pb was higher than standard level of the FAO, MAFF, FDA, and WHO but Cr and Zn was lower than the standard of international organizations. Risk index (HQ) of Cd and Pb metals was higher than one but for other metals were lower than one. Consuming this kind of fish is a serious threat for consumers of the region. &nbsp; Manuscript profile

        &nbsp; &nbsp; &nbsp; &nbsp;In this study common mushroom stalks meal (MSM), as a huge waste of commercial mushroom culturing, was conducted to evaluate as a replacement for fish meal in diets of juvenile rainbow trout in an initial 46 days feeding trial. Two diets containing 0% and %100 MSM were formulated. Significant differences in survival rate (%) between the fish meal based control diet and diets containing up to 100% MSM was not observed (p&gt;0.05). Feed conversion ratio (FCR) of common diet (1.35&plusmn;0.036) showed significantly increased with fish meal diet (p&lt;0.05). However, MSM diet showed the best results in BWG (16.50&plusmn;5.185 %), SGR (1.29&plusmn;0.055), FCR (1.26&plusmn;0.066), HIS (1.53&plusmn;0.235 %) and VSI (20.52&plusmn;0.763 %) in comparison to common diet (p&lt;0.05). Based on the results, juvenile rainbow trout diet contain up to 100% MSM without any loss of growth performance, thereby showing higher growth properties in comparison with fish meal. This study shows that mushroom stalks meal can replace 100% of fish meal in experimental rainbow trout diets. Further trials to identify the best formula between MSM and fish meal are necessary.

        &nbsp;&nbsp;&nbsp;&nbsp;Rainbow trout is the most importantspecies ofcold water fishes in Iran and the feeding diets which improve the quality and growth of this fish are of great importance. In this study, 360 youth of rainbow trout fingerlings with approximate weight of 100&plusmn;0.04g were fed with different concentrations of sesame seed (%) in their diets instead of fish meal for 120 days. Feeding diets were prepared in 4 concentration levels (15, 20 and 25 percent of mealed sesame seed instead of fish meal, and same diet without sesame seed meal for the witness group)&nbsp; in triplicates as a completely random design experiment. The highest rate of weight gain (281.5&plusmn;0.08g), length gain (27.5&plusmn;0.01 cm), specific growth rate (1.45&plusmn;0.01), protein efficiency rate (2.09&plusmn;0.01) and food conversion ratio (1.4&plusmn;0.01) were obtained in treatment 3. The lowest rate of weight gain (245&plusmn;0.04g), length gain (26.5&plusmn;0.01 cm), specific growth rate (1.2&plusmn;0.04), protein efficiency (1.45&plusmn;0.04) and food conversion ratio (1.9&plusmn;0.04) was obtained in the witness treatment. The obtained results indicated a significant difference among the witness and treatments (P&lt;0.001). Alternation of sesame seed improved the growth and health of rainbow trout&nbsp; fingerlings. These results demonstrated that sesame seed meal can be used as an alternative ingredient in its feeding diet, instead of fish meal.&nbsp; Manuscript profile

        In this study, in order to assess qualitatively the status fish ponds, three fish ponds in northern Iran were investigated. Water and fish samples were collected in the mid-June, August and October, 2014. Some parameters (temperature, pH, dissolved oxygen, electrical conductivity, transparency (SD), nitrate and phosphate) were measured on the sites while the others (Chlorophyll-a, Fe, Zn, total weight, total length, K and phytoplankton identification) were estimated at the laboratory using standard methods and procedures. The principal component analysis (PCA) and One-Way ANOVA were conducted to statistical analysis. The result showed that, during the study period, in the three fish ponds, the phytoplankton population was dominated by Bacillariophyceae (25%) followed by Chlorophyceae (23%) and Cyanophyceae (22%). Among Cyanophyceae, Chroococcus (35%) and Merismopedia (25%) were dominant. The results obtained from PCA indicated, the first three axes explain more than of 80 % of the total variance. The first axes (PC1) include EC, Chl-a, pH and SD. Also, significant differences were observed in temperature, DO, No3, Chl-a concentration, total weight and total length over the period of three months (p &lt; 0.05). The observations in this study suggest that based on the determined desirable limits for water quality in fish ponds, and based on obtained results from the fish biometry and K,&nbsp; generally, studied ponds are suitable for fish farming and can supply optimum and healthy production. &nbsp;&nbsp; &nbsp; Manuscript profile

        Today, consumption of seafood has a special place among consumers. Consumption of seafood can lead to the transmission of bacterial pathogens of primary or secondary origin, among the most important of these bacteria are Vibrio species that are naturally found in aquatic environments and in the bodies of aquatic organisms. Every year, many cases of food poisoning caused by Vibrio species are reported in consumed fish. The purpose of this research is to investigate the level of Vibrio contamination of raw fish sold in Shahrekord city. In this research, 50 fish samples were prepared from 30 fish and aquatic supply stores in Shahrekord city and then analyzed at the Nutrition and Organic Products Research Center of Islamic Azad University, Shahrekord branch. Vibrio parahaemolyticus, Vibrio cholerae, Vibrio vulnificus, Vibrio mimicus and Vibrio alginolyticus can be mentioned among the most important species investigated. Then, based on the presence or absence of grown spores, 40% of the meat of the studied samples (20 pieces) were infected with Vibrio. The high abundance of Vibrio species in the samples confirms the lack of hygiene in the fish and its products preparation and distribution centers. It seems that the processing stations and the method of transporting and distributing fish do not have proper hygiene. Manuscript profile

        The kinetic mechanism of fatty acids or FA degradation and microbial growth rate or MGR in seafood are very important. In this research, the interaction effect of propolis addition (at different concentrations) and storage times on the FA oxidation kinetics and its inhibitory role on the suppression of bacterial/fungi growth of stored FFB at -18°C was evaluated. The FA degradation (or microbial growth) rates in FFB during storage period follows the zero-order kinetics. The lowest growth rate (log10 CFU/g) of total viable count (3.66) and fungi (2.43) of FFB was observed after three-months storage in the P-IV, that corresponded to the lowest degradation rate of peroxide value (k0=0.0462 meq O2/kg oil/day) and the highest sensory evaluation scores. Generally, adding 0.4% propolis to FFB and storing them at -18°C for up to 86 days (as the best shelf life) can effectively prevent lipid oxidation and microbial growth and improve sensory quality.
