Effect of different salinity on body composition of shyrbot fish was investigated. Shyrbot fingerlings with an average weight of 3.96 grams were reared under different salinities (0, 3, 6, 9, 12 and 15g). Analysis of body composition showed a significant effect of different levels of salinity on protein, fat, moisture and ash (p<0.01) of the fishes. The highest level of protein, ash and moisture and lowest amount of fat were obtained in 15ppt salinity followed by 12 and 9ppt salinity. The highest amount of fat was obtained in freshwater followed by 3 and 6ppt. In higher salinities (9, 12 & 15ppt) low fat and energy stored. The results suggest that Shyrbot fingerlings until 6ppt salinity can be easily developed.
