In this research effect of fish protein hydrolysate (FPH) on growth performance and Protein efficiency intake of Huso huso were investigated. 297 larvae with initial average weight of 45 gram were divided into 9 groups, for 3 treatments, each one in 3 replicate and reared in 9 circular ponds (3m2). The fishes were fed with 3 diets, basal diet only (control) and diets supplemented with 5% and 10% FPH. The result showed that dietary FPH levels significantly influenced the growth. Compared with the control group, with BWI of 578.56, mean BWI of two treatment groups were increased (681.08 and 604.06). APU and PER also were increased significantly in fish fed with diets supplemented with 5% and 10% FPH, (11, 16 and 17 % for APU and 1.11, 1.22 and 1.03 for PER). In general, with the supplementation of FPH, particularly at dose of 5% the growth performance, Protein efficiency Ratio and Apparent Protein Utilization of the Huso huso can be improved effectively.
