This study was conducted to evaluate the effect of replacing dietary fish meal with canola meal on growth performance, survival and body composition of Siberian sturgeon (Acipenser baerii Brandt). Five isonitrogenous (45% crude protein) and isocaloric (18.53 kJg-1) diets were formulated by replacing 0 (control), 10 (C10), 20 (C20), 30 (C30) and 40% (C40) of fish meal with canola meal. Juvenile fish with initial weight of 22.80 ± 0.34 g (mean ± SD) with five treatments and three replications were fed for 10 weeks. At the end of the experiment, growth performance, survival and body composition of fish were measured. The result of this study showed that there were significant differences in growth indices and body composition of fish fed different diets (P0.05), but significant differences was observed in moisture content of body in fish fed different diets (P
