    Study on brood stock management of Litopenaeus vannamei using imported post larvae (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In order to domesticate Litopenaeus vannamei as a solution to single species shrimp aquaculture of Penaeus indicus and to reduce risk of shrimp culture in emergency cases, this study was carried out. Initially the postlarvae reared from imported L. vannamei were cultured. After culture season the adult shrimps were transported to greenhouse ponds for wintering. It is then relocated to hatchery saloon. After eye stalk ablation and maturation the female brood stocks were introduced to matured male for copulation at ponds. During the study period, male and female shrimps attained full maturation at end – April by temperature over 25ºC, the copulation process was started significantly. Finally of the 12 instances of copulation, one instance resulted nauplii production. The best maturation was observed at 28 ֯C ±1 and salinity30 to 33PPT and pH of 8 to 8.3 Fresh sea worms and squid showed the highest effect on fecundity in brood stocks. Besides, the spring season was obtained to be the best period for brood stock production in Bushehr province.

    Proximate and fatty acid composition of liver and fatty tissue of patincatfish (Pangasianodon hypophthalmus) (2018)
    Details
    Publication Date: 2021-05-19
    Description: The visceral storage fat and liver of patin catfish (Pangasianodon hypophthalmus) are normally discarded, which incurs cost and can cause environmental pollution. However, these may be potential sources to extract fish oil. The proximate and fatty acid compositions of liver and fatty tissue of patin catfish were investigated to evaluate the suitability of these by-products for extracting fish oil. Fat was extracted using a low temperature solvent extraction method. The average fat content of fatty tissue and liver of females were 77.64 and 11.71%, respectively, whereas in males this was73.23 and 9.59%, respectively. Fatty acids found in the extracted oil of these byproducts were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6.The major fatty acids presented in these tissues were palmitic (C16:0), oleic (C18:1n-9), and linoleic acid (C18:2 n-6). The total amount of polyunsaturated fatty acids of liver from male and female patin catfish were 13.31 and 13.30%, respectively, whereas in the fatty tissue these were11.64 and 12.09%, respectively. The n-3 to n-6 ratios of liver and fatty tissue of females were 1.61and 0.95, respectively, whereas in male fish these were 1.31 and 1.05, respectively. Results of this study indicated that the liver and fatty tissues of patin catfish are suitable sources of fish oil specifically due to the presence of monounsaturated and n-3 polyunsaturated fatty acids.

    Effect of using various amounts of patin (Pangasianodon hypophthalmus) fish oil on physical and chemical properties of moisturizing hand cream (2019)
    Details
    Publication Date: 2021-05-19
    Description: Hand cream is used for rehydrating and improving skin properties. The skin is the first point of contact with the environment. Thus having healthy skin with proper barrier properties is quite important. The beneficial effects of fish oil on skin make it a favorable ingredient to be used in hand care products. In the present study, the efficacy and stability of various hand cream formulations using 0, 1.0, 2.5 and 5.0% of fish oil were investigated and compared. The appearance, odor, texture, and pH of formulations containing 1 and 2.5% of fish oil remained stable in very good qualities during the storage, whereas the related values to the appearance and texture of formulation containing 5.0% of fish oil at the end of 6 months of storage at 45°C were significantly (p〈0.05) lower than other formulations and previous evaluations of this formulation. Weight loss was not observed in all formulations under study.

    Optimum management of warmwater fish FarmsStocking, Capacity determination, Growth rate and Brood stock managements and harvesting (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was conducted to codify the guideline and indexes of optimal management in warm-water fish farms to attain sustainable aquaculture which they are population density, species diversity, brood stock'smanagements, , capacity determination,growth and harvesting managements in cultural ponds. As results, these guideline and indexes were codifies for these fish farms and propagation centers.It's obviously that these sustainable patterns can be used for improving of permanent development for this aquacultural industry.

    Refined oil production from patin catfish (Pangasianodon hypophthalmus) by-products (2018)
    Details
    Publication Date: 2021-05-19
    Description: In this study, oil was extracted from the liver and visceral fat of Patin (Pangasianodon hypophthalmus) and refined. The yield of oil after refining was 49.98%. The major yield loss (34.20%) happened during the degumming procedure. Fatty acids found in the crude and refined oil were C12:0, C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C18:2, C18:3, C18:4, C20:0, C20:1, C20:4, C20:5, and C22:6. The dominant saturated, monounsaturated and polyunsaturated fatty acids were C16:0, C18:1 n-9, and C18:2 n-6, respectively. The total amounts of monounsaturated fatty acids did not change significantly during refining procedure (p〉0.05), whereas the total amount of saturated and polyunsaturated fatty acids changed significantly (p〈0.05). The n-3 to n-6 ratios of crude, degummed, neutralized, bleached, and deodorized oils were 1.11, 1.06, 1.05, 1.02, and 1.01, respectively.
