    Production of soybean meal-based feed and its effect on growth performance of western white shrimp (Litopenaeus vannamei) in earthen pond (2018)
    Details
    Publication Date: 2021-05-19
    Description: The effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (Litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. There was no significant difference in final weight (mean final weights were 15.7±0.88 and 15.6±0.52 g for the experimental and control treatments, respectively) between the treatments during the 115 days rearing period. There were no difference in FCR: 1.80±0.08 and 1.76±0.06, protein efficiency: 1.46±0.01 and 1.45±0.05, SGR: 2.38±0.04 and 2.38±0.03, final production: 2853.58±64.14 and 2864.83±168.57 kg/ha and survival rate: 91±1.78, 92±2.41% between experimental and control treatments, respectively (p〉0.05) but net protein utilization in experimental treatment (17.05±0.38 g) and in the control (11.80±0.26 g) revealed significant differences (p〈0.05). It is concluded that the experimental feed with 42% soybean meal was more efficient than the commercial feed on some growth parameters of western white shrimp.

    Production of artificial diets for female broodstock of western white shrimp (Litopenaeus vannamei) and study on their singular effect (2018)
    Details
    Publication Date: 2021-05-19
    Description: Advantages of pelleted feeds in terms of storage, transportation and lower costs compared to natural fresh feed justified the replacement of artificial feeds instead of natural ones partially on maturation performances. This study comprised nine treatments (with three replications) including control treatment: polychaete worm (Perinereis nuntia), Squid and calf liver (natural feed); T1: pellet feed with 50% crude protein and 8% crude lipid+ Perinereis nuntia, Squid and calf liver; T2: pellet feed with 50% crude protein and 10% crude lipid+ Perinereis nuntia, Squid and calf liver; T3: pellet feed with 40% crude protein and 10% crude lipid+ Perinereis nuntia, Squid and calf liver; T4: pellet feed with 40% crude protein and 8% crude lipid+ Perinereis nuntia, Squid and calf liver Perinereis nuntia; T5: pellet feed with 50% crude protein and 10% crude lipid; T6: pellet feed with 50% crude protein and 8% crude lipid; T7: pellet feed with 40% crude protein and 10% crude lipid; T8: pellet feed with 40% crude protein and 8% crude lipid. In treatments 1, 2, 3 and 4, 50% of the natural diets were removed and pellet foods used instead. The amount of pellet feeds that given daily, was 3.5% of shrimp broodstock biomass. In treatments 5, 6, 7 and 8, the amount of pellet feeds that given daily was 7.5% daily. Feeding was done 4 times a day. GSI in the control (3.23%), treatment 3 (3.20%) and treatment 6 (3.02%) were significantly higher than that in the other treatments (p〈0.05). Absolute fecundity in the control (29980 eggs) and treatment 3 (29683 eggs) was significantly higher than other treatments (p〈0.05). HSI reached the lowest level in treatment 8 (2.14%). But in treatments 3 and 5 was more than control, but did not any statistical significant (p〉0.05). Survival rate in the treatment 8 (26.66%) was significantly lower than other treatments (p〈0.05). Generally, In the treatment 3, with the elimination of 50% of the natural foods, and the use of pellet food instead of them, result of comparative indices of reproduction were in desirable proportions.

    Publication Date: 2021-05-19
    Description: Nowadays, white spot virus disease is serious threat for breeding and culture industry of shrimp. In this study was increasing resistance of shrimp against white spot virus by using modern methods such as shrimp vaccination with inactivated viruses and recombinant proteins. The aim of this study were determine the growth and survival rates vaccinated and non-vaccinated of Litopenaeus vannamei (5 to 15 and 12 to 26 day), that were challenged with white spot virus in 40 and 60 day rearing. This study consisted two separate groups were vaccinated and non-vaccinated with 11 treatments experimental and each of replicate was stocked 1000 pieces by post larva of 5 to15 and 12 to 26 day. After vaccination, two groups of post larvae exposed to the white spot virus at 40 and 60 day, one groups no exposure to the virus. Samplings were randomly of shrimp in 40, 60 and 80 days 10 pieces each of treatment experimental and measured mean of weight and length. Also, number of deaths was recorded at morning and evening daily and calculated survival rate at the end of study. The results showed growth rate of post larvae vaccinated (5 to15 day) which exposed to white spot virus at 40 and 60 was significantly lower than non-vaccinated of post larval, while the growth rate of post larval exposed to virus in 60 day was significantly increased. On the other hand, growth rate of post larval vaccination (12 to 26 day) exposed to virus in 60 day compared with post larval vaccination (5 to 15 and 12 to 26) exposed to virus in 40 and 60 days was significantly increased. Hence, growth rate was significantly increased in post larval vaccinated (5 to 15 and 12 to 26) which non-exposed to virus. Although the survival rate was post larval vaccinated (12 to 26 days) exposed to virus Post larvae in 60 day higher than post larval were exposed to virus in 40 and 60, but no significant differences were observed. However, relative mortality of post larval vaccination in 12 to 26 day compared with post larval vaccination in 5 to 15 days exposed to virus were significantly lower. Considering growth and survival index was improved of post larval vaccination can be concluded that the optimum age for vaccination against white spot virus of L.vannamei was 12 to 26 day.

    Comparative study of the effects of HUFA in dry diets and natural foods on fecundity and egg diameter of female broodstock of white leg shrimp (Litopenaeus vannamei) (2018)
    Details
    Publication Date: 2021-05-19
    Description: During 2 months (from April to June, 2008) we studied the suitable quantity of Highly Unsaturated Fatty Acids (HUFA) for desirable fecundity and egg diameter of female broodstock of white leg shrimp (Litopenaeus vannamei). Similar dry food containing Isonitrogeneous material (31.5% protein) and Isolipid (6.9% lipid) was used but with different levels of HUFA (1, 2 and 3%). Also, the HUFA of natural foods (Perinereis worm, melalis bivalvia and cuttlefish) was analyzed. We compared the effects of four levels of dietary HUFA (1, 2 & 3 % HUFA of dry diets and the average HUFA of natural diets) on fecundity and egg diameter of female broodstock of white leg shrimp. The fecundity and egg diameter of natural diet and HUFA 3% were not significantly different (P〉0.05). The fecundity of natural diet and HUFA 3% was significantly higher than the other two treatments (P〈0.05) and also the egg diameter of HUFA 3% and natural diet was significantly higher than the other two treatments (P〈0.05). According to the results of fecundity and egg diameter measurements, both natural and HUFA 3% diets are suggested as suitable for white leg shrimp breeding.

    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.

    Description: Anemia nauplii and rotifier are considered as the most important live food in aquaculture because of their high nutritional quality, suitable size and mobility. The survival rate and resistance of white shrimp (Litopenaus vannamei) postlarvae fed by Artemia urmiana, Brachinus plicatilis and concentrated food were investigated. Larvae at the stage of Protozoae 1 were stocked in 14 liters plastic containers filled by 6 liters of water. There were 75 larvae per liter in each container. The larvae were fed in 3 treatments: T1 (rotifier), T2 (Artemia) and T3 (concentrated food). Each treatment was repeated 3 times and used during Protozoae 1 (PLC} to Post-larvae 5 (PLO stages. Data analysis was done through Duncan Test. We observed that from Mysis 1 stage to PL1 the rotifier can be used for shrimp feeding and from this stage to PL5, Artemia nauplii can be used as food for the larvae. To evaluate the quality of larvae, the physiological resistance tests were conducted against formalin and salinity in different periods of time (30, 60 and 90 minutes). We found that at the PLC stage, the maximum survival (100%) in formalin tests (I 0Oppm) and (200ppm) and salinity test (15ppt) was related to feeding the shrimp larvae with rotifier. However, at the PL5 stage, the maximum survival (100%) under the same conditions was related to application of Artemia nauplii food. The concentrated food showed the minimum survival in all tests.
