Effects of Carbohydrate and Water Temperature on Nutrient and Energy Digestibility of Juvenile and Grower Rockfish, Sebastes schlegeli Sang-Min Lee* and Minh Anh Pham Department of Marine Bioscience and Technology, Gangneung-Wonju National University, Gangneung 210-702, Korea ABSTRACT : A factorial (4×2×2) experimental design was employed to determine apparent digestibilities of dry matter (DM), protein, lipid, energy and nitrogen-free extract (NFE) of the test diets containing either α-potato starch (A-PS), β-potato starch (B-PS), β-corn starch (B-CS) or dextrin (DEX) as dietary carbohydrate energy for juvenile (average weight 30 g) and grower (average weight 300 g) rockfish reared at 13°C and 20°C. Chromic oxide was used as an inert marker. Feces were collected by fecal collectors attached to rearing tanks from triplicate groups of juvenile and grower rockfish. Digestibilities of DM, energy and NFE of the test diets were significantly affected by dietary carbohydrate and water temperature (p
