Abstract: In this study, we investigated effects of different feeds (live food (Artemia+Drosophila sp.), wet feed (Spleen+Liver) and commercial feed) and different water temperatures (9.10±0.85 and 15.00±0.50°C) on meat yield, Survival Rate (SR), Feed Conversion Ratio (FCR), Condition Factor (CF) and growth in Rainbow trout, Oncorhynchus mykiss (Walbaum) fingerlings. The fingerlings had 0.23±0.04 g mean initial weight. The study lasted a total of 16 weeks and carried out according to completely randomized factorial experimental design (3x3x2). At the end of the experimental period, final weights of fish having about the same initial weights showed big differences. The highest final weight was 13.05±0.21 g from the higher temperature and commercial feed group. The differences between the groups were found statistically significant (p<0.05). In terms of feed conversion ratio, very different values were observed among the groups and their differences were also statistically significant (p<0.01). At the end of research, carcass weights differences between the results of the commercial feed, wet feed and live food groups were statistically significant (p<0.05). In terms of condition factor values, the differences between the groups were insignificant. In terms of Hepatosomatic (HSI) and Viscerasomatic (VSI) indices the differences between the results of the groups were found statistically significant (p<0.05).
