    Production of monosex female population of Rainbow Trout by use of 17-B estradiol as direct method (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In many species of finfish, females exhibit higher growth rates than males and achieve larger sizes. In addition, in some species, males mature before reaching marketable size. Therefore, there is great interest from the fish farmers to produce all-female stocks. In this project tried to reversing the sex of rainbow trout larvae by 17 estradiol and direct method, further more finding the optimum dose of this natural estrogen for endocrine sex reversion of Rainbow trout (O. mykiss). Four experimental treatments were designed with doses of 10, 20, 30 and 40 mg/kgf. Trout which treated with 40 mg/kgf yielded 96% female and greatest growth.

    Comparison of growth and survival rate between import and native rainbow trout (Oncorhynchus mykiss) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Rainbow trout is only species of cold water fishes which is rearing and propagation in Iranian fishery farms. Along of develop aquaculture industries increase request of best produces such as trout eyed eggs and larva. For this reason fishery farmers must be to provide that the way of import of other countries, such as: Denmark, Norway and France. As for this importance subject and unknown basic information about preference ratio for doing it, we needed to study about that to answer the suppliant questions. In this study carried out 3 test groups (3 treatments with 3 repetitions) and compared specific growth rate (SGR), condition factor (CF) and survival rate (SVR) between in this groups. Statistical analysis were significantly difference of increase rate of length and weight in French group with other groups (p〈0.05). Compared of main factors (SGR, CF, SVR) in French test group were significantly difference with other groups (p〈0.05). Survival rate percentage in Iranian treatments (SVR=%67) were significantly with the others (p〈0.05). This ratio respectively in Danish and French treatment was %54 and %48.
