The effect of soy bean concentrate (SPH) was evaluated on growth index and body composition of Siberian Sturgeon (A. baerii) for 8 weeks. A total of 120 Acipenser baerii juveniles (initial body weight 186.44 ±31.3gr mean ±SD) (4 treatment) were reared in 12 fiberglass tanks and fed to the saturation with four experimental diets in which fish meal was replaced by SPH at 0%, 10%, 20% and 30% namely SPH0 ,SPH10, SPH20 and SPH30, respectively. Biometry was carried out monthly. At the end of experiment, 30% of total fish killed and transported to laboratory for determination of body composition. Result showed no significant differences in final weight (FW), specific growth rate (SGR), protein efficiency ratio (PER) and feed efficiency ratio (FCR) of fish fed SPH20 and SPH30 compared to control diet. In addition, body protein and lipid were increased by increasing of soy bean concentrate in diets. The highest body protein and lipid were recorded in fish fed SPH20. Result of this investigation showed that soy bean concentrate was potentially suitable for fish meal replacement in diets of Acipenser baerii.
