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.
