    Description: Increasing of biodiversity and reduction of production costs and alo increasing of shrimp production are the main elements of production security and continuation of aquaculture of shrimp in the country. The hypothesis of this study is made on the basis of aquaculture of pacific white legged prawn , litopenaeus vannamei, and that is economically better than Indian white prawn in bushehr area . This study was carried out with the objectives of determination of bionormatives of pacific white legget prawn and yield estimation per squar meter and has been compared with Indian white prawn. During 1384-85. In this study , the field operations were carried out after primary preparation and water enrichment with the juvenile prawn (pL 15) with 20 prawn per squar meter in the 3 ponds . During the study the phisico-chemical parameters such as water temperature, ocsysion, pH,two times per day , in the morning and evening and salinity , transpiration and depth water , only one time in a day were measured .The health of prawns and also sampling for the calculation of body weight were carried out in every 10 days . Feeding in the first month was randomly and after that was being continued based on the mean of the body weight. The results of this study have showed that the growth of this species is very fast so that during 90 days with the capacity of 20 prawns per squar , meter, it can be reached to 19.59 gr body weight with the growth rate of 0.217 gr . The mean of total production was 2737.5 kg per hectar with FCR=1 . During this study the salinity from 33 ppt to 54 ppt , water temperature from 24.3°c to 35.2°c , occsysion from 2.4 to 11.89 mg/l , pH from 7.83 to 9.01 , transparency from 35 cm to 90 cm and water depth from 100cm to 145 cm were measured and recorded . In the second year, the comparison of growth rate of white legged prawn and Indian white prawn was carried out in the four ponds. The results of this study showed that during 110 days. White legged prawns was reached to average of body weight 14.66 gr and Indian white shrimp, reached to 10.75 gr. The economical assessment showed that white legged prawn has an economical advantage around 2.59 times during 110 days with the capacity of 35 prawns per hectar.

    Publication Date: 2021-05-19
    Description: Aquaculture is the fastest growing food industry in the world. Shrimp culture industry is also part of it, unfortunately, like other marine animal culture economic losses caused by the disease has been one of the major challenges of this industry. The major cause of mortality in shrimp hatcheries and rearing centers is related to water quality and the presence of pathogenic bacteria and parasites. These are common opportunistic microorganisms in the hatchery, rearing centers, flora and living food but poor conditions of culture are caused diseases. Since the development of aquaculture in the countries need health management, one of the important additional rings in the shrimp strategic plan is specific pathogen free shrimp production, which has been addressed in this plan. Specific pathogen free shrimp define as the shrimps which are free of the specific pathogens listed in world organization for animal health (OIE). These factors should be conclusively diagnosed and can be isolated from shrimp hatcheries and culture system. Therefore in this project screening and surveillance of shrimp in several generations according to the list of OIE were done and they were monitored for of bacterial pathogens (Necrosis Hepatopancreas Bacteria) and parasites (Microsporidian and Gregarins). At total 756 pieces of shrimp, 6 sample of dry food and 97 samples of live foods were controlled and tested. 1.35 percent of live foods were positive for NHPB and 5.6 percent of pre broodstocks have eppicommensal and microsporidia which were disposed in quarantine phase. Because of biosecurity and surveillance system establishment, there were no bacterial or parasitic isolation or diagnosis during SPF shrimp production.

    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.

    Description: Marine polychaete worms living in different beds from coastal areas, so different cultures can be different effects on their development. The evaluation of this research initially, marine polychaete worms were collected in low tidal sea areas from Gulf Persian coast in Bushehr. During several stages of sampling do more than 2000 pieces of worm were taken and then transferred to Bandarga Shrimp Research Station (Iran Shrimp Research Center). So based on an observation the desired species identification (Perinereis nuntia). Then 400 pieces worm selected and transferred to tanks maintain immature worm (fiberglass tanks with dimensions of 2×2×0.5 m with 15 cm sand on floor). The results showed that even the worms (P. nuntia) in vitro reached sexual maturity able to spawn in captivity conditions and were absolute fecundity of 16010 ± 17630 eggs. After incubation eggs, larval culture into the plastic tank with 70 cm diameter, larval (1.5 to 2 mm) were introduced with density 2000 (pieces/m^2). In this research used to three different beds (tidal, filled with water all of time and wet bed) with three different food types (food shrimp, seaweed and vegetable waste), so there were 9 experimental treatments. All experimental treatments harvested and estimate production in each of them after 270 days. The seaweed tidal treatment with amount of 21.17 g/m^2 had best results and the all of wet treatments with 0 g/m^2 was the lowest production. Compare of beds showed that the tidal treatments have significant difference with other beds in growth factors (e.g. mean weight, survival percentage and total production) (P〈0.05). And for effect of food kind on growth factors, the result of difference foods in tidal treatment were analyzed. According this mater any treatments have no significant difference together in growth factors (e.g. mean weight, survival percentage and total production) (P〉0.05).

    Description: For the successful breeding of western white shrimps (Litopenaeus vannamei) brooders (females and males), we used cuttle fish (Sepia pharaonis) and sand worm (Perinereis nuntica) of Persian Gulf as principle feeds, 3 times a day, and from cow livier and edible bivalve meat (Solen brevis) of Persian Gulf, as secondary feeds, 1 time a day. Nutritional value of Sepia pharaonis, Perinereis nuntica and Solen brevis, with determination of the amount of fatty acids such as arachidonic acid (20:4n-6), stearic acid (18:00), oleic acid (18:1n-9), palmitic acid, palmitoleic acid (16:1n-7), eicosapentaenoic acid (20:5n-3) and docosahexaenoic acid, essential amino acids inclusive arginine, lysine, leucine, isoleusine, threonine, valine, histidine, phenylalanine, methionine, tryptophane and crude protein, crude fat, crude fiber, ash and moisture were done in laboratory. The results showed that, the amount of essential amino acides and nonessential amino acides (in the more causes) in Sepia pharaonis were more than Solen brevis and in Solen brevis more than Perinereis nuntica. Only nonessential amino acides, glysine and alanine in Solen brevis were more than Sepia pharaonis. Also in chemical analysis of wet feeds determined that, crude protein percent in cattle fish was 2.9 times and 2.2 times more than Solen brevis and Perinereis nuntica, respectively. The crude fat in cattle fish was 2.1 times and 1.6 times more than Solen brevis and Perinereis nuntica respectively. Tottaly, the amount of essential fatty acides in Sepia pharaonis and Perinereis nuntica were more than Solen brevis, and in Sepia pharaonis and Perinereis nuntica were almost, equal. Total lipids of Sepia pharaonis, Perinereis nuntica and Solen brevis determined 7.92, 5.90 and 3.63 percent respectively. Totally the percent of fatty acids in cattle fish and Perinereis nuntica is almost equal and was more than Solen brevis meat. We can noted that, the Sepia pharaonis and Perinereis nuntica are suitable as principle feed and Solen brevis and cow livier, as secondary feed for L.vannamei broodstock maturation.

    Description: DNA barcode is a short, standard well known sequence of cytochrome oxidase І gene. By using this DNA sequence can be realized that each animal, plant or fungus belongs to which species. in this research, samples were collected from imported cultured shrimp Litopenaeus vannamei and and 6 Persian Gulf and Oman Sea shrimp species which classified based on traditional systematically as: Penaeus semisulcatus, Fenneropenaeus merguiensis, Metapenaeus affinis, Parapenaeopsis Stylifera and Fenneropenaeus indicus. After examination of DNA barcode sequence, molecular and bioinformatics operations of each sequence in the Consortium for the Barcode of Life (CBOL) and National Center for Biotechnology Information (NCBI), phylogenetic analysis of each sample was determined and similarity of each sample with NCBI and CBOL database was checked and the closest species to each sample were specified. According to the results different samples of L. vannamei, . banded P.semisulcatus, F. merguiensis and F. indicus have more than 97% similarity to the same species of other countries. non banded P.semisulcatus had 80.07% similarity to banded P.semisulcatus, M. affinis samples had 90.3% similarity to Metapenaeus ensis and Parap. Stylifera had 93.44% similarity to Parapenaeopsis coromandelica in the CBOL. This funding confirmed the need for further investigation and possible announcement of new species.
