Abstract :In this study, it was aimed to compare meat yields and nutrient contents of male and female rainbow trout individuals obtained from pond and cage units of two fish farms located in two provinces, Kayseri and Kahramanmaraş, Turkey. The results showed that the highest meat yield was in female individuals reared in the pond unit of the farm in Kahramanmaraş with 55.70% and the lowest meat yield was in male individuals reared in the pond unit of the farm in Kayseri with 47.17%. When all males and females were compared, it was determined that female individuals had higher meat yield and no significant differences were found between pond and cage groups. The highest condition factor insert ignore into journalissuearticles values(1.55); was found in the Kahramanmaraş cage male group, while there was no significant difference in other groups. HSI values were higher in male individuals and VSI values were higher in the cage groups. Protein values were found to be higher in females. The highest protein contents were determined in the Kahramanmaraş cage female insert ignore into journalissuearticles values(20.16%);, Kahramanmaraş pond female insert ignore into journalissuearticles values(20.11%);, and Kayseri cage female insert ignore into journalissuearticles values(19.89%); groups. Moreover, the highest lipid values were found in the Kahramanmaraş cage male insert ignore into journalissuearticles values(7.36%); and Kahramanmaraş pond male insert ignore into journalissuearticles values(7.16%); groups. The highest moisture was observed in the Kayseri pond male group with 75.84%. The ash content did not differ between groups.
