The present study was conducted to compare growth performance, feed utilization, muscle composition, and postprandial glycemic glycogen responses of juvenile Amur sturgeon, Acipenser schrenckii, fed different carbohydrate diets in order select the most appropriate sources for this species. Six experimental were formulated containing 22% glucose, fructose, maltose, dextrin, α-starch or cornstarch, respectively. Triplicate groups 20 fish (average weight: (4.7 ± 0.1) g, means SD) randomly one six eight weeks. Results showed that weight gain rate highest dextrin (716.0%) diet (782.9%), lowest fructose (333.2%). Specific efficiency a similar pattern. Apparent digestibility dietary sturgeon glucose> maltose> dextrin> > cornstarch diet; apparent protein fructose> cornstarch> diet. Contents moisture, ash crude lipid significantly affected by difference (P < 0.05), but no significant observed content 0.05). Dietary plasma glucose liver concentrations periods after feeding According rate, whereas deemed be an inadequate source.
