  Background and Objective: Great cormorant is dependent on aquatic ecosystems. The breeding success and daily survival rate of the Great Cormorant Phalacrocorax carbo sienensis (early April until late of July) was studied in 2009 in a colony at Amirkelayeh international wetland, south of the Caspian Sea, Iran. Method: In this study, Mayfield method was use to estimated nest survival during incubation and nestling and post- nestling stages. Findings: The mean  of clutch size was 2.88±0.8 eggs in each nest Based on this method, daily survival rate nests in incubation period was 98.3%,in nestling and post-nestling were 99.4%and 100% respectively. The overall breeding success was 56.4%. Discussion and Conclusion: Results of this study showed there were higher stages of chick rearing than the incubation period and no losses occurred in fledged chicks. Some climatic factors such as high wind and prolonged rain had more impacts and losses in incubation period (30.7%).In other hand, chicks are more sensitive in nestling stage. Results suggest that Amirkelayeh colony site needs more improvement mitigation for better conservation of the cormorant colony in breeding period. Manuscript profile

        Considering that one of the most important points of probiotic products is the survival rate of live microbes during storage time, so the aim of this study was to determine the effect of different amounts of pH, salt and temperature on survival rate of Lactobacillus casei in milk during 30 days of storing. For this purpose, at first four erlene Meyers with capacity of 2 litters were selected and 1.5 litter of sterilized milk was added to each of them. Two percent of yoghourt starter was inoculated to each of the first, second and third erlenes and 2% sterilized milk was inoculated to the forth erlene as control group and samples were incubated at 42 ˚C until the pH of first to third samples reached 3.5, 4.5 and 5.5 respectively. Then the erlenes were heated at 90 ˚C for 10 minutes to inactivate the yoghourt starter bacteria and then 500 ml of each sample in first, second, third and forth erlenes was transported to three sterilized caped glass containers and so  four groups consisting of 3 glasses were produced and in each collection 0,  2% and 4% of salt was added to first, second and third samples respectively and then 5 ml of McFarland solution containing 3× 109 cfu/ml of Lactobacillus casei was inoculated to each of the samples. This Procedure was repeated 12 times and obtained samples were stored at about 4˚C in the first six repetitions and at about 25˚C in the second six repetitions. The number of Lactobacillus casei in each of samples was counted soon after production, 4, 8, 12, 16 and 30 days after storing by pour plate method in MRS agar and obtained means were analyzed statistically. According to repeated measures analysis of variance and one way analysis of variance, the mean number of live Lactobacillus casei in samples with pH of 6.5 and 5.5 was significantly more than their numbers in the samples with pH of 4.5 and 3.5 and in the samples stored at 4˚C the number was more than those stored at 25˚C (P<0.01). Whereas salt concentration did not show significant effect on survival rate of Lactobacillus casei in milk. These results showed that milk with pH of 6.5 and 5.5 containing maximum salt of 4%  at 4˚C for about 30 days and at 25˚C for about 15 days is a good environment for storage and transport of  Lactobacillus casei to the consumers.

  This study was designed to investigate the influence of supplementing multi-enzyme in feed on growth and survival rate of rainbow trout fish. The multi-enzyme were incorporated into a commercial pellet ration to constitute three experimental diets containing 500, 1000, 1500 gram kemin phytase multi-enzyme per one ton feed intake, while a fourth diet without the multi-enzyme supplement served as the control diet. The diets were offered to rainbow trout (150 g average weight) in quadruplicate pools (each treatment) for 40 days. Fish were sampled at 10, 20, 30 and 40 days after commencement of the feeding trial to determine feed conversion ratio (FCR), weight and length rate and survival rate. Results of our study indicated that effect of different supplementing multi-enzyme levels on feed conversion ratio (FCR), weight and length rate and survival rate, there was not any meaning relation in dose rates (p>0.05). According to affect of type and concentrates of enzyme on animal response, we can recommend that type or concentrates of consummated kemin- phytase multi-enzyme is not suitable for rainbow trout.

  This study was performed for a period of 3 weeks, on the survival of Polychaeta  Perinereis nuntia, at various salinities, temperatures and dissolved oxygen levels, in laboratory condition. Among these factors, salinity had the most significant effecton the survival of P. nuntia. There were one control group and 3 treatments at different salinities, includeing 1/5 (7.1 ppt), 3/5 (21.3 ppt) and 7/5 (49.7 ppt) of sea water salinity. The salinity of the control group was 35.5 ppt. Maximum rate of survival was observed in control group with 70% mortality and the minimum was in 7.1 ppt treatment by full fatality in the first week. There was significant difference in survival rate of various temperature treatments (p<0.05). Minimum and maximum survival rate in temperature treatments were in 44º Ϲ with 33% and 24 º Ϲ with 70%, respectively. Dissolved oxygen concentration was the least effective factor on survival of P. nuntia. The highest survival rate was in 5-6 ppm of dissolved oxygen concentration with 80% survival and the lowest was in 7-8 ppm with 73% survival. Results showed that the maximum survival rate of Perinereis nuntia was in dissolved oxygen treatments and the highest mortality rates were in different concentrations of salinity. Manuscript profile

  6 - Effect of enriched Artemia urmiana with highly unsaturated fatty acid and vitamin C on the reproduction performance of Pterophyllum scalare
  S. H. Mousavi H. Ershad Z. Moradkhani B. Falahatkar
  Artemia (Artemia urmiana) was added to diets of Angelfish and various factors: fecundity, fertilization rate, hatching rate and larvae survival rate and interval between continuous spawning and total time for 8 spawning (did you run 8 spawning cycles, this is not clear) More

  Artemia (Artemia urmiana) was added to diets of Angelfish and various factors: fecundity, fertilization rate, hatching rate and larvae survival rate and interval between continuous spawning and total time for 8 spawning (did you run 8 spawning cycles, this is not clear) for Angelfish. five diets were tested (n=3): a 40% crude protein diet (control); control diet + live Artemia, live Artemia; live  artemia +  unsaturated fatty acid live Artemia + unsaturated fatty acid + 1gr vitamin C. Broodstock Angelfish (18 pair) were kept in a 50 L aquarium (28 ± 1°C, pH 7.5-8.3,  hardness <170ppm). Fish were fed 4 times per day between 7:00 and 23:00. The average rate of fecundity was 378 eggs, 98.9% fertilization, 97.5% hatching for fish fed the live artemia + fatty acid. The artemia + fatty acid + 0.5 g vitamin C resulted in the highest larvae survival (93.3%) which was significantly higher than the control group (P < 0.05). The shortest period for 8 spawning cycles (43 days, 6 day interval) was for the Artemia + fatty acid + 1 g vitamin C. Feeding live food reduced the time for 8 spawning cycles and increasing fecundity, fertilization rate, hatching rate and larvae survival rate. Adding artemia decreases this time between spawns and would be a useful ingredient for continuous spawning operations and is likely to be economically for broodstock operations because of increased efficiency even though the feed cost would be higher.

  We aimed to evaluate the effect of compost earthworm on the growth factors and survival rate of Guppy larvae in comparison with commercial Biomar food. Guppy larvae were divided into three groups with three different food rations including group 1 (control) with Biomar food, group two with dried compost earthworm diet and the third group was fed with Biomar as an equal mixture of dried compost earthworm. The larvae rearing lasted for five weeks and then, the data were analyzed statistically. The survival rate (SR) and growth factors such as specific growth rate (SGR), body weight index (BWI) and daily growth rate (GR), in the third group compared to the other groups, and the second group were better than the control group. Significant changes were observed between the groups too (P≤0.05). Thus, the use of dried compost earthworm and Biomar food simultaneously improves the survival rate and growth factors. It is recommended for using in diet. 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
