Introduction: Caspian kutum (Rutilus frisii) is of great importance among consumers. The aim of this study is to investigate the changes in the fatty acid profiles of fish caught in east of Sari and west of Noshahr. Materials and Methods: The studied fish (three fish from each gender) were purchased in winter and spring from Sari Shahid Beheshti Cooperative and the Veterans Cooperative of Noshahr (east and west of Mazandaran province, respectively). Biochemical analysis and fatty acid profile were determined by the application of gas chromatography using standard methods. Results: Stearic acid, oleic acid, and DHA were the highest in Sari in winter being the significantly different from other fatty acids (p < 0.05). Total fatty acids in male and female fish from Noshahr and male fish from Sari were significantly lower in spring than in the others, and male and female fish from Nowshahr contained relatively higher total fatty acids in winter. Maximum DHA values were higher than EPA in both sexes, seasons, and regions. The chemical composition of male and female fish did not differ significantly in both seasons and regions (p > 0.05). SFA percentages in both sexes and regions were generally higher in winter than in spring, while PUFA percentages in both sexes and regions were higher in spring than in winter. The percentage of ω-3 fatty acids (41.12%) in winter samples of Noshahr was higher than that (30.91%) in Sari, and it was higher in spring samples of Sari (55.27%) than that of Noshahr (17.29%). The lowest total ratios of ω-3/ω-6 were obtained in Sari (3.12) in male fish in winter and in Noshahr (3.23) in spring. The highest PUFA/SFA ratios were observed in Sari (1.9) and Noshahr (0.74) kutum in spring and winter, respectively. Conclusion: Fish examined in winter contained more fatty acids (especially DHA and EPA) in the muscle and are therefore more important for human consumption. The two regions, two seasons, and two sexes had significant effects on body biochemical composition and fatty acid profile of Caspian Sea kutum. Manuscript profile

Considering the economic value of fish belong to Cyprinidae family, and the importance of ecology in the exploitation of marine resources, diversity identification of whitefish (Rutilus frisii kutum) was conducted in the Sefidrud, Karganroud, Anzali lagoon, Chamkhaleh and Chelvand estuaries in Gilan province. For this purpose, 30 fish were collected from each river. After measuring thirteen morphometric and 9 meristic characters,the mean, standard deviation, minimum and maximum sizes, and coefficient of variation of all studied parameters in each river were calculated. 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 <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’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’s diversity.

Kutum (Rutilus frisii kutum) is one of the most important fishes of the Caspian Sea which migrates annually to Iranian rivers such as Shirood River. In this research mutual effects of age have been analyzed on some sperm parameters (volume, density, spermatocrit and motility percent) of kutum (Rutilus frisii kutum) and the artificial propagation in Shirood River. For this reason acquired sperm from 30 male broods (2, 3, 4, 5 and 6 years old) were combined with ova of 30 females. Maximum weight (975 g) and total length (47.25 cm) were related to 6-year-old male broods, while minimum weight (373.33 g) and total length (35.67 cm) have been observed in 2-year-old male broods. The highest sperm volume (5.22 ml), spermatozoa density (45×109 n/ml), spermatoicrit (39.3%) and spermatozoa motility (77.4%) were related to 5, 2, 2 and 4 years old stocks, respectively. In other hand the least sperm volume (3.03 ml), spermatozoa density (30×109 n/ml), spermatoicrit (30.3%) and spermatozoa motility (74%) were related to 2, 6, 4 and 6 years old stocks, respectively. A peak percentage of fertilization (95.2%) and hatching (83%) occurred in 4-year-old, while a minimum percentage of fertilization (88.5%) and hatching (77.6%) were showed for 6 and 2 years old stocks. Statistically there were not any significant differences between different ages as sperm volume (P=0.323), spermatozoa density (P=0.539), spermatoicrit (P=0.187) spermatozoa motility (P=0.164), but fertilization percent average did not indicate significant differences between different ages groups (P=0.016). So4 years old male brood stocks are economically the best choice for artificial propagation. Manuscript profile

Abstract[1]This research carried out to evaluate the effect of different levels of dietary vitamin C premix and some indexes of growth, survival and resistance to some certain environmental factors (temperature, salinity) on the white fish larvae R. frisii kutum. Fish larvae (weight 1 gr.) was prepared from bony fish reproduction and culture center was located in Sijuval City. Diet was containing four levels of 0, 200, 500 and 1000 mg per kg of vitamin C premix in three replications for 8 weeks for feeding of fish larvae were considered. 480 samples (an average weight of 1 g) were introduced to 12 plastic tubs (40 fish per tub). The fish were fed daily to 4% of body weight. The fish at the end of culture period was exposed under stress situation (31 oC) and salinity (14 ppt) and their survival was assessed. Results showed that the highest mean (±standard deviation) weight increased following in treatment of 1000mg per kg premix of vitamin C and least was in control treatment (without premix of vitamin C) but it was not significant. Study of growth indices, PBWI, SGR, FCR and survival rate in fish fed with premix of vitamin C 1000mg per Kg diet had significantly been higher than other treatments (P<0.05). Temperature and salinity stresses showed that fish fed with different levels of premix of vitamin C had more survival than fish fed no premix of vitamin C. Based on the results, it can be stated that premix vitamin C can plays an important role in enhancing growth performance and resistance to environment conditions (temperature, salinity) in R. frisii kutum larvae.* Corresponding authors; zeinab_shadehi@yahoo.com 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<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

Heavy metal pollution in marine environments and the potential for bioaccumulation of contaminants have been considered as a serious threat for a long time. These contaminants accumulate in fish body and then transferred through the food chain to humans. The aim of this study was to determine the heavy metals cadmium, lead, arsenic, mercury and copper and iron metals in muscle and fish oil (Rutilus frisii kutum ،Clupeonella cultriventris ،Liza saliens). Three samples of Rutilus frisii kutum ،Clupeonella cultriventris and Liza saliens were caught in Mahmoud Abad area. One part of the muscle was dried by freeze drying method and another part was used to extract the oil. Then, using the atomic absorption spectrometric and Mercury Analyzer heavy metals concentrations were determined in muscle and fish oil. The results of muscle showed the highest accumulation of mercury (0.347±0.018), cadmium (0.08±0.001), copper (1.2156±0.059) and iron (2.643±0.231) in Rutilus frisii kutum and the highest level of lead (0.3593±0.015) and arsenic (0.0892±0.001) in Liza saliens. Moreover, in the fish oils samples, lead and mercury had the highest concentrations. The heavy metals in the samples were lower than or close to international standards.

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(1/7×107cfu/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.

Recently, the ecology of the Caspian Sea has undergone with increasing development of human activities and industrial wastewater discharges. Heavy metal compounds are undegredable pollutants and are able to accumulate in the environment. They can affect the food chain and biological individuals such as fish species. 40 and 22 samples of Rutilus frisii kutum and Liza saliens were collected in central and eastern parts of southern Caspian Sea in 2008, respectively. All samples were analyzed based on standard methods using Atomic Absorption instrument (Thermo, M5 model). Results of this study showed that the amount of Zn in fish muscle of L. saliens was maximum (415.3±196.3 µg/g. dw). The concentrations of Cu, Ni, Pb, Cd and Hg in fish muscle of L. saliens were 10.85 ±11.02, 0.41 ±0.84, 2.63 ±2.67, 0.63 ±1.07 and 1.30 ±0.16 µg/g. dw, respectively. The concentrations of Cu, Ni, Pb, Cd and Hg in fish muscle of R. frisii kutum were 0.40 ±0.46, 0.0132 ±0.007 and 1.26 ±0.75 µg/g. dw, respectively. 7 heavy metals were below the established limits of different countries. The pearson correlation analysis showed that between Zn and Hg there were a significant negative correlation indicating a decrease of Hg toxcicity with increasing Zn concentration. THQs for individual metals were lower than USEPA guidelines value of 1 in young and adults human. Thus, consumption of 6 kg R. frisii kutum and/or L. saliens per capita cannot be risky for young and adults consumers. Manuscript profile

The proteins in fish, as well as other aquatic animals has nowadays become an important protein source in many people's diets around the world and as a results, there has been a growing interest to ensure the health of this important food source. Heavy metals due to their specific physical and chemical characteristics as well as their effects on various ecosystems are considered as a major contaminant of marine environments. Therefore determining the level of heavy metals in water and aquatic species, as a link in the food chain of human beings, is of a great importance. In this study, levels of some heavy metals were evaluated,using  flame atomic absorption spectroscopy (A.A.S) technique, in tissues of two commonly consumed fish in Iran namely Rutilus frisii kutum and Cyprinus carpio collected from the south coastline of the Caspian Sea. The average concentration of  Zn , Cd , Fe and Cu were detected as (μg g-1) dry weight of Rutilus frisii kutum’s tissues : 32.400 1.015, 1.205 0.157, 90.716 0.200 and 9.455 0.215 respectively. These values for Cyprinus carpio were detected as: 30.204 0.282, 1.353 0.179, 85.887 0.267 and 9.144 0.178.  Manuscript profile

The kutum (Rutilus frissi kutum) of the most economic species of fish which should artificially breed to improves the stock of it. One of the critical points of its culture is finding the best and cheap diet for this species. The aim of this study is to study the comparison between the growth performance and survival rate of fish which fed Eisenia fotidae and concentrate diet. The experiment was designed in a semi intensive system with stable physicochemical parameters. 180 fish with initial average weight 1.75 g and 6.20 cm length were stocked in 12 tanks and fed with different levels of Eisenia foetidae (0.25%, 50% and 75%) during 60 days. The BWI%, SGR, FCR, CF, ADG and survival rate were estimated. The results showed the best growth and nutrition performance and observed in treatments which fed Eisnenia foetidae, all of which fed Eisena foetidae, but with increasing the percentage of Eisena foetidae, all of the parameters were decreased. In conclusion, usage of Eisena foetidae had not benefited the effects on growth performance of kutum and this ingredient should be used in lower levels in diet of kutum juveniles.             Manuscript profile
