    Effect of different dietary levels of plant protein on growth indexes of White Leg shrimp (2018)
    Details
    Publication Date: 2021-05-19
    Description: The influence of different dietary levels of plant protein (30, 50 and 70%) on growth indices of White Leg Shrimp (Litopenaeus vannamei) fed with an original 38 percent protein was assessed and compared with that of the commercial shrimp diet. The average weight gain at the end of the culture period in treatment 1 (30% plant protein and 70% animal protein), was 5.89 plus or minus 0.06 grams, for treatment 2 (50% plant protein and 50% animal protein), was 6.22 plus or minus 0.25 grams, for treatment 3 (70% plant protein and 30% animal protein), was 6.19 plus or minus 0.24 grams and for the control treatment (20% plant protein and 80% animal protein), was 6.42 plus or minus 0.40 grams. Our study of the influence of experimental and control diets on growth indices including growth rate (GR), food conversion ratio (FCR), protein efficiency ratio (PER), specific growth rate (SGR), and average daily gain (ADG), demonstrated that the indices were better in the control compared to the treatments. No significant difference was found among the treatments and between the treatments and the control for the indices (P〉0.05). The percent of net protein utilization (NPU) in treatment 1 was significantly more than other treatments (P0.05). We also found that the application of diets containing 50% plant protein (with 20% soybean meal), and 70% plant protein (with 41.72% soybean meal), can decrease diet costs. Cost of one kilogram of pellet, in treatments 1, 2, 3 were, 83.3%, 68.3% and 53.3% lower than the control diet respectively. Decrease of cost in treatment 2 and 3, in comparison to control in terms of lowering shrimp production cost is very important.

    Study on effect of enriched Artemia with (HUFA) on reproductive parameters and comparing with current method (used marine worm) in Litopenaeus vannamei (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Nowadays, the use of live food enrichment is very common in aquaculture and as a practical method introduced. Artemia a potential food source and quality is suitable, it will have used for feeding fish and crustaceans (shrimp). In this study, Artemia enriched with unsaturated fatty acids used for increase the sexual maturity of the white leg shrimp (Litopenaeus vannamei). Thus, the young brood stocks transferred to Bandarga Research station. In order to achieve optimal weight, Brood stocks were feeding by food concentrate and food frozen fresh. In this study such as 3 treatments each with 3 replicates, which brood stocks were stocking in the fiberglass thank with density 2 to 3 (pieces/m2). They were feeding with meals different including 1) squid , pen shale and marine polychaeta worm (Perinereis nuntia), 2) squid , pen shale and Artemia biomass "fransiscan", 3) squid , pen shale and Artemia biomass enriched with unsaturated fatty acid (HUFA) SPARI SELCO solution after were eye ablation. The results showed that sexual maturity increased in the brood stocks fed with Artemia enriched which with significantly higher brood stocks fed with Artemia biomass and the marine worm (P 〈0.05) whereas significant difference was not found in the rate of sexual maturity brood stocks fed with Artemia biomass and marine worm (P〉 0.05). The other hand, histological studies showed that brood stocks fed with Artemia enriched than other two treatments contain were many mature follicles ready for ovulation. However, there was more absolute fecundity in the brood stocks fed with Artemia enriched, but don't found any significant differences in competition with other two treatments (P 〉 0.05). In addition, during this period, measured and recorded all factors physicochemical water and environment daily. Following this study showed that if the Artemia enriched as part of the diet can both caused eliminate unsaturated fatty acid deficiency diet and improved ovarian development and increase sexual maturity brood stocks female in a short interval. Finally, the results analyzed with statistical software spss 9.0, one way ANOVA and Tukey test.

    Determination of biotechniqe and bionormative of breeding and culturing of penaeus merguiensis de Man in Bushehr Area (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: To introduce the native commercial shrimp species to aquaculture industry, the Iranian Fisheries Research Organization conducted a project to investigate the possibility of reproduction and cultivation of the banana shrimp (Penaeus merguensis). The present work has been carried out from 21st March 2001 in two phase, reproduction and cultivation, in Iran Shrimp Research Center. The main objectives of this study was to find the possibility of reproduction and cultivation of banana shrimp with emphasis on its cost and benefit and to find if this species could be introduced to aquaculture industry in Iran. In this work, 42 brood stocks of banana shrimp caught in Jask waters and were transported to Bushehr. The shrimps were reproduced in aquaculture research station, and then cultivated in 0.4 ha ponds in Heleh region. Most of the broodstocks perished, due to long distance of Jask from Bushehr province, or had problem in hatching. Finally 8 of broodstock shrimps spawned . In 3 cases, the reared naplii larva suffered high mortality, but the other 5 spawners bread successfully. The post larvae were introduced to the shrimp ponds. The primary stocking was 360,000 larvae, introduced to each of two 4 m 3 tanks. The survival in both tanks for mysis stage was 83% but for PL stages, the survival was 5% for Tank 1 due to disease outbreak (until PL 24), and 62% for Tank 2. On 10 th June 2001 the PL 24 were stocked into the ponds but unfortunately due to adaptation problem, all of the shrimps perished. It seems that banana shrimp couldn t to be adapted to the pond condition in Heleh region. On the basis of the results, the reproduction of the banana shrimps is achievable, but broodstocks needs to be transferred to reproduction areas as soon as possible to reduce stress on the shrimps. Our finding shows that the optimum conditions of salinity and temperature for growth of the reared banana shrimp in Heleh region is 33ppt and 30 °C, respectively.
