Abant trout Salmo trutta abanticus were grown for 154 days at three salinities of 0, 9 or 18 to assess mass gain, condition factor, food conversion ratio and food consumption. Appetite was significantly higher at 0 than at salinities of 9 or 18. Salinities >18 may have detrimental effects on biomass production. The mean ± s.e . of the condition factor at the three salinities were 1·29 ± 0·20 at 0, 1·22 ± 0·22 at 9 and 1·10 ± 0·20 at 18. Fish reared at a salinity of 0 showed higher mass gain, food conversion ratio and food consumption.
