Abstract: Due to the anthropogenic activities, the native fish species of Kashmir Schizothoracine is being declining day by day. Therefore an attempt has been made to culture the fish on artificial diets and evaluate the effects of artificial diet on the growth and feed conversion ratio. In the experiment, a total of 75 fishes were equally divided into five groups. A twelve week feeding trail was carried out in floating cages (1×1×1m), in five groups to evaluate the use of soybean as a dietary protein source for Schizothorax curvifrons. Soybean was incorporated at 0, 20, 30, 40 and 50% of total feed. Each dietary treatment was tested in five groups of fishes each group having 15 fish. Fish were fed daily at the rate of 1.5% of body weight. Percentage weight gain, specific growth rate (SGR), survival and feed conversion ratio (FCR) in fish fed diet with 20% and 30% substitution of dietary feed by soybean were significant (P<0.05). No significant differences (P>0.05) were observed in fish fed by 40% and 50% soybean meal. The results showed that soybean can be incorporated in diet of Schizothorax curvifrons up to 30% with no adverse effects on growth, survival and feed conversion ratio.
