    Description: In this project, The nutritional effects of Sargassum illicifolium Chabahar bay-Oman Sea, on growth and survival rates of whiteleg shrimp (Litopenaeus vannamei) were studied. The seaweed collected from 6 coastal area, rinsed, dried, powdered and measured the nutritional values in laboratory for surveying statistically. According to the high nutritional value of Tis coastal seaweed, this variate seaweed powder, replaced with protein resources (fish meal and Soy and Wheat) of whiteleg shrimp feed which was formulated by Havorash feed factory of Boshehr in four treatments (A: as control without any replacement) B: with 5%, C: 10 % and D: 15% seaweed replacement, each with three replicates in order to obtain isonitrogenus 33% CP., and Isocaloric (13% fat and 15% carbohydrate) feed. The weighed milled ingredients were carefully mixed using a laboratory food mixer. The mixtures were primed with 30% hot water to yield a suitable pulp. Wet diets were made into 2 mm pellet size and dried at 40 °C in a drying cabinet and maintained in standard condition which was used according to daily need shrimp, calculated by each 10 days biometry. Water stability and absorbtion capacity of the pellets in sea water were measured and compared statistically. Juvenile shrimps (Initial body weghit =3 g) brought from Jask hatchery, acclimazed for one week in chabahar hatchery condition and feeding daily 3-5% body weight. Abiotical parameters and weight and lenght biometries were measured two days and 10 days, repectively. After 45 days and final biometry, FCR, CF, SGR, caracas analysis, muscle colourimetery with HPLC were done, tasted with pp Plot for determining the parametric data and statistically differences using one – way ANOVA, Duncan test of SPSS software. The Tis coastal seaweed with 9.8% CP, 2% lipid and 23% carbohydrate had higher nutritional value compared to the other gathered seaweed. Also amino acid and fatty acid profiles, vitamins and minerals were measured in all seaweed samples each, with three replications. As result, The water stability of D feed treatment in seawater (98%) and C (97%) had statistical differences with A and B (95% stability) (P〈0.05). Water absorption capacity of feeds after one hour immersion in seawater showed significance difference between D (110%) and three others, C(100%), B(85% and control(80%) (P〈0.05). Shrimp growth data, after the end of experiment revealed that seaweed feed treatments had no any differences with control group significantly. However, the absolute growth rate datas of D treatment were higher than others and the lower weight and lenght were measured in control group shrimp. FCR had difference between seaweed treatments and control statistically. There are no any differences between caracas lipid treatments (P〉0.05) but Cholestrol content of, showed differences between all, significantly (P〈0.05) which was the highest (121.68±12.12) in D and the lowest in A (147.92±11.02). Feed treatment D and C performed colour changes pink partial orang and pink in shrimp muscle with no any difference compared to white and none colour in shrimp were fed B and A feed treatments . It seems this colour changing can be playing a major role in market accebtability.

    Description: In this research, the nutritional effects of Sargassum ilicifolium Chabahar Bay, Oman Sea, on cholesterol levels of white-leg shrimp (Litopenaeus vannamei) were studied. The seaweed was collected from coastal areas, rinsed, dried, powdered and the nutritional values were measured in the laboratory. A part of protein resources of shrimp feed replaced with seaweed powder in four treatments (D: as control without any replacement) C: with 5%, B: 10 % and A: 15% seaweed replacement, each with three replicates in order to obtain isonitrogenus 33% CP., and Isocaloric (13% fat and 15% carbohydrate) feed. Dried diets were used according to the daily need of shrimp, calculated after each 10 day biometry. Water stability and absorption capacity of the pellets in sea water were measured and compared statistically. Juvenile shrimps (Initial body weight=3 g) were acclimated for one week under hatchery conditions and were fed 3-5% of their body weight. Abiotic parameters, weight and length biometry were measured on day two and day 10, respectively. After 45 days final biometry, body analysis were measured, and muscle colorimeter were conducted using HPLC. There were no significant differences (p〉0.05) between body lipid among treatments, but cholesterol content (mg/100gWW) showed significant differences (p〈0.05), the lowest (121.68±12.12) was in treatment A, and the highest in D (147.92±11.02). Treatments A and B showed color changes to pink- partial orange and pink in shrimp muscle with no differences compared to white and no color in shrimp in treatments C and D. It seems that this color change plays a major role in market acceptability.

    Description: This survey is part of the investigation on feasibility of introduction of Litopenaeus vannamei Boone, 1931 in shrimp culture industry of Iran. The objective was evaluation of the adaptation of the white leg shrimp, L. vannamei to brackish groundwaters of the Bafgh area in Yazd province. Around 120000 shrimp postlarvae (PL7 and 15) were stocked in four 0.15ha earthen ponds (17 and 23 ind/m super(2)) in July 2005 and the culture period took about four months. Physicochemical and biological factors were studied during the culture. Shrimps were fed with commercial feed of the L. vannamei. Results showed low survival (19.2%) and growth (2-2.5g mean body weight). Based on the assessments, the limnological factors were most unfavorable elements causing the low growth in the shrimp. Concentration of K, Ca, Mg and Na Fe (II and III), different heavy metals, nitrogenous compounds, water hardness and the season and thermal periods are probably the most essential factors affecting production yield of the shrimp because of underground origin of the water. Also, the structure of ponds and drainages, presence of invasive water plants and insects may have affected the survival and growth of the shrimp as well.

    Description: The aim of this study was to evaluate the effects of biofloc (with addition of spoilage date palm extract (SDE) and molasses as sugar sources) on bacterial load of water, growth performance and intestine of Litopenaeus vannamei using diets containing different protein levels. Four biofloc treatments were designated including the biofloc treatment with SDE + a diet containing 25% protein (P25), biofloc treatment with molasses + a diet containing 25% protein (M25), biofloc treatment with SDE + a diet containing 15% protein (P15), biofloc treatment with molasses + a diet containing 15% protein (M15) and the control treatment with a diet containing 38% protein (Control). All treatments were conducted in triplicates. A 35-day study was conducted on 35 juvenile shrimp (with average weight of 5.37±0.33 g) which randomly stocked in fifteen tanks (each 300 L) at a stocking density of 175 shrimp m−3. The highest amounts of growth parameters (weight gain, Feed Conversion Ratio (FCR), growth rate and survival) were observed in P25 treatment and the lowest amounts of growth parameters were observed in the control (P〈0.05). Moreover, the highest percentages of body weight index, feed efficiency and specific growth rate were observed in P25 and the lowest percentages of those were observed in M15 treatment (P〈0.05). Results showed that the number of total heterotrophic bacteria was increased during the study and the numbers of total heterotrophic bacteria in all biofloc treatments were higher than that of the control. The highest and the lowest numbers of fungi, vibrio and bacillus were found in P25 treatment and the control treatment, respectively. The length of the epithelial cells of the intestine was increased in all biofloc treatments as compared to the control but this difference was significant in the first abdominal segment, only. The result demonstrated that the effects of SDE were better than molasses, which could be due to the presence of useful compounds such as the growth and immunity promoters in it.

    Description: Nowadays, Litopenaeus vannamei are the most important species of farmed penaeidae shrimp in the world that is rapidly replacing native species in areas aquaculture. Due to demand increase for this species culture, shrimp displacement to different areas may be associated with some potential pathogens transferred to new areas farmed. Therefore, in this study were prepared bi-osecurity conditions for specific disease-free production of L. vannamei. Thereafter, three populations (Molokaei, High health and mix of Molokaei and High health) of the shrimp various reserves were detected base on origin and genetic indexes such as: observed heterozygosity, expected heterozygosity, allele frequency, coefficient inbreeding, genetic differentiation, genetic distance and genetic identity. On the other hand, epidemiological studies indicate non pathogens (viral, bacterial, fungal and parasitic) recognition of different populations selected in the quarantine salon. The bioassay results showed that the average weight and length of the populations of High health and Mix significantly greater than was a population of Molokaei. The shrimp populations were stocked in fiberglass tank (five ton) and were kept separated in the quarantine salon. During maintenance shrimp of populations in the quarantine salon were evaluated living and non-living pathogens with PCR, microbiology and biochemical methods. There is not any pathogens detection from shrimp populations stocking in the quarantine salon, so the shrimps were carried over to pond for broodstock culture of specific pathogenic free.

    Description: The influence of different percents of plant protein (30, 50 and 70) in the diet of white leg shrimp (Litopenaeus vannamei) with 38 percent protein, in comparison with a commercial shrimp diet (Fenneropenaeus indicus) with 39 percent protein (contain20 percent plant protein) was studied. Initial weight of shrimp was 10±1 gram. The average increase of shrimp weight in the end of culture period in experimental treatment 1 (contain 30 percent plant protein and 70 percent animal protein), 5.89±0.06 gram, experimental treatment 2 (contain 50 percent plant protein and 50 percent animal protein), 6.22±0.25 gram, experimental treatment 3 (contain 70 percent plant protein and 30 percent animal protein) 6/19±0/24 gram and in the control treatment (contain 20 percent plant protein and 80 percent animal protein) 6/42±0/40 were measured. Generally in the study of influence of experimental diets and control diet on the growth rate(GR), food conversion rate (FCR), protein efficiency ratio (PER), specific growth rate (SGR), average daily gain (ADG), demonstrate that, mentioned parameters in the control treatment is better than experimental treatments. But no significant difference measured between them (p〉0/05). Also results showed that, application of diets contain 50 percent of plant protein (with 22 percent soybean meal), and 70 percent of plant protein (with 72 percent soybean meal), can decrease costs of diet preparation and therefore shrimp production.

    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: This study was conducted in order to optimizing of the biological condition and enhancing of the harvest efficiency for cultured shrimps of Guater site. Experimental design was consisted of three treatments and each treatment with three replications (totally 9 ponds with 600 m^2 area for each pond). After preparing and watering of ponds, the ponds was stocked with shrimp post larves in a density of 0.007±0.001 g (or 20 numbers per m^2) per m^2. After 35 days, the fingerlings of gray mullet were released to shrimp ponds in densities of 0/100 m^2 (T1/), 2/100 m^2 (T2) and 4/100 m^2 (T3). During experiment, the physicochemical parameters of water (temperature, O_2, pH, water transparency and salinity) were measured daily for two times (morning and afternoon). Also, the nitrate, nitrite, ammonia, phosphate and silicate concentrations and BOD5 as well as chlorophyll (a), phytoplanktons and zooplanktons were measured every 15 days one time. To determine the organic values of the bottom sediment of the ponds, monthly sampling was conducted. Health status of shrimps was investigated monthly too. Growth rate, mean weight, survival value, Food conversion ratios (FCR) and total shrimp harvest (Kg) were measured after 107 days rearing in ponds. ANOVA analysis showed significant differences between treatments. The highest (212 Kg, 3533 Kg; weight mean was18.4 g for each shrimp) and lowest (187 Kg, 3116 Kg; weight mean was16.23 g for each shrimp) of harvested shrimps were yielded in T3 and T1 respectively. There was not significant differences between treatments in terms of survival rate (P〉0.05). After 107 days rearing, the highest (1.27 0.2) and lowest (1.2 0.1) of FCR were observed in T_3 and T_1 respectively. Although, there were no significant differences between T_2 and T_3 in ammonia, O_2, Total organic material, pH and BOD5, but, T_2 and T_3 had significant differences with T_1 in these parameters. In this study, 27 genus of phytoplanktons belonged to Diatoms (Bacillariophyceae), blue-green algal (Cyanophyceae) and dinoflagellates (Dinophyceae) were identified. Diatoms with 20 genus had more abundance than dinoflagellates (6 genus) and blue-green algal (1 genus). Also, 7 orders of zooplanktons including copepod, mollusks, nauplius of crustacean and rhizopoda were identified. Health investigation of T1 (without shrimp) showed more pathogenic pollution (parasites and bacteria) than in treatments with shrimp. In this regard, among bacteria, the Vibrio genus (V.Alginoliticus and V.Fluvialis) had more abundance and among parasites zoothamnium sp and Epistylis sp were identified which more abundance was for zoothamnium sp. In conclusion, our results concluded that mixed culturing of white shrimp and grey mullet in optimum densities is possible and is caused more production of shrimp.
