Growth rate and total production of shrimp in T2 compared to that of T5 and T6 and results showed significant differences. No significant differences were detected with other treatments. Growth rate in T3 significantly increased compared to other treatments. Nitrogen conversion rate of biomass (tilapia and shrimp) in all treatments except T1 statistically demonstrated an increasing rate as the tilapia-shrimp ratio was increased.

Three fisheries indicators in catch were: 1) percentage of mature fish, with 100% as target 2) percent of specimens with optimum length, with 100% as target and 3) percentage of mega-spawners, with 0% as target, and if no upper size limit exists, 30-40% as representative of reasonable stock structure. Over this period, the condition factor and relative weight had a decreasing trend. The range of length with optimum yield was between 40 and 48 cm. The mega-spawner measured as fish a size larger than 48 cm. According to these three indicators, the percentage of mature (fork length>40cm), optimum size and mega-spawners were 62.0, 40.9 and 12.5% in 1991-92 which decreased less than 50, 38.2 and 8%, in the years 1992-2011, respectively. The length structure is a matter of concern. Therefore, for reservation and rebuilt of kutum in the Caspian Sea, the target was to let all (100%) fish spawn at least once, using bigger mesh size in cod end (e.g. 35mm, during whole fishing season). The aim was also to implement a fishing strategy that result no (0%) mega-spawners being caught, and the main catch focus on optimum length. *Corresponding author}, Keywords = {Stock assessment, Fisheries indicators, Spawner fish, Caspian Sea, Iran}, volume = {21}, Number = {2}, pages = {53-64}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.110055}, url = {http://isfj.ir/article-1-708-en.html}, eprint = {http://isfj.ir/article-1-708-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2012} } @article{ author = {Fallahi, M. and Sharifian, M. and Toloii, M.H. and Amiri, A. and DaghighRoohi, J.}, title = {The effect of anaerobic fermentation of cow manure on culture of Rutilus frisii Kutum and comparison of survival and growth factors versus traditional feeding}, abstract ={Rutilus firisii kutum is one of the important fish in Caspian Sea that has significant economical role to the region.

A total of 11 farmed A. nudiventris specimens (7 male and 4 female) were stocked in groups of 4 fish in eight fiberglass tanks (4 tons capacity) on the basis of their sex. Males were fed with a diet with no soybean but containing vitamins. Females were fed with a diet containing soybean and vitamins with 38-40% protein, 13-15% fat, 19.5-20Mj/kg energy, respectively. GnRH was used for artificial propagation of Acipenser nudiventris brood stocks twice for females (dose 10μg/kg with 80:20 ration) and during one occasion for males with a dose of 20 μg/kg. The results of the study indicated that food composition (soybean and vitamins C and E) played a significant and positive role in the reproduction system for females. No significant effect of treatment was observed in Testosterone levels between mature (Mean ±SD: 60.6±8.07ng/ml) and immature (24.42±4.87ng/ml) males, Likewise, no significant differences were found in17α-Hydroxy Progestrone for female (Mean ±SD: 0.106±0.019ng/ml) and for immature fishes (0.031±0.006ng/ml) significant differences was detected in the concentration of Albomine (1.54±0.05mg/dl for females and 1.35±0.07mg/dl for immature females), but there were no significant differences in other biochemical parameters including Glocose, Cortisol, Chlosterole and Triglisride in males and females. There were no significant differences in total weight and length, WBC, RBC, Hb, Hct, MCH, MCHC and MCV parameters in males and females.

In present study Hemiculter lucisculus was as a new host for Ichthyobodo necator, Myxobolus sp., Discocotyle sp. and Diplozoon sp. also except Saccocoelium obseum from Liza auratus and Corynosoma stromosum from Gasterosteus aculeatus, the other parasites were reported for the first time in Iran. *Corresponding}, Keywords = {Parasites, Zardi River, Caspian Sea, Fish}, volume = {21}, Number = {4}, pages = {151-156}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.110096}, url = {http://isfj.ir/article-1-809-en.html}, eprint = {http://isfj.ir/article-1-809-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2013} } @article{ author = {Pourkazemi, M. and ShakibiDaryakenari, A. and Kalbasi, M.R. and Abdolhay, H. and BaradaranNoveiri, S.}, title = {Short term preservation of spermatozoa of rainbow trout (Oncorhynchus mykiss)}, abstract ={Short term preservation of spermatozoa of salmonid fishes for practical use, increasing of reproduction potentials and reducing of expenses, has an important role in hatcheries. In this study spermatozoan motility and fertilization rate of 29 commercially cultured rainbow trout were examined. Semen was collected by abdominal stripping at the volume of 4.49±1 (mean±SD) ml and sperm concentration was determined by heamocytometer following 1:600 dilution with saline solution (0.9% NaCl). To find the effects of preservation time on fertilization capacity, samples were diluted with extender (Glucose 54gL-1, Tris 0.5gL-1, DMSO 9% , Egg yolk 20%) and held at 3 different cool conditions : room temperature (+15°C), refrigerator (+5°C) and crashed ice (+ 1-2°C) and sperm motility followed up each 30 mins until complete ceasation. Fertilization, hatching and larval stage rate were determined after 24, 48 and 72 hours. Results showed that the motility of sperm samples held at 15 °C and 5°C were completely ceased after 2 and 24 hours respectively. However it lasted up to 144 hours at1-2°C.Fertilization, hatching and larval stage rates of sperm samples hold at 1- 2°C were 68.45% , 62.1% and 58.2% (after 24 hours), 53.2% , 43.2% and 40.9% (after 48 hours) and 36.6% , 31.6% and 23.7% after 72 hours, respectively, and all showed a significant decrease compared with control (90.32%, 83.27% and 81.12% respectively). Comparing the results showed that holding samples in test tubes at 1-2°C is the best method for short term storage of rainbow trout spermatozoa.}, Keywords = {Spermatozoa, Short term preservation, Oncorhynchus mykiss, Motility rate, Fertilization rate}, volume = {21}, Number = {4}, pages = {157-164}, publisher = {IFSRI}, doi = {10.22092/ISFJ.2017.110097}, url = {http://isfj.ir/article-1-810-en.html}, eprint = {http://isfj.ir/article-1-810-en.pdf}, journal = {ISFJ}, issn = {1026-1354}, eissn = {2322-5998}, year = {2013} }
