Özet

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. (C) 2011 The Authors Journal of Fish Biology (C) 2011 The Fisheries Society of the British Isles
