A160 day feeding trial was performed to determine the effects of .dietary carbohydrate to lipid ratio (CHO:L) on growth and body composition of hybrid tilapia (40.6 ± 0.43 g, initial weight). Eight artificial diets were formulated, representing two protein levels (25 and 30%) , within each level four carbohydrate to lipid ratios (2,4,6 and 8 CHO:L ratio) were tested. Growth rates in fish differed (P<0.05) with CHO:L ratio. Weight gain ('%) was significantly lower (P<0.05) in fish fed diets containing low crude protein. Maximum weight gain (363.5%), SGR (0.%% /day), FCE (43.4%). protein retention (24.4%) and energy retention (15.7%) were observed in fish fed a 6 CHO:L ratio. Fish fed either high protein and low protein within 2 and 8 CHO:L ratios tended to produce.' leaver growth and feed conversion efficiency. The different CHO:L ratios had effect on percentage body lipid. HSI (%) offish increased, however, total lipid of liver decreased (P<0.05) as CHO:L increased- The.se results indicate that hybrid tilapia efficiently utilize carbohydrate to lipid ratio for growth performance when increased up to 6.0 CHO:L ratio. Higher dietary CHO:L ratio up to 6 with low protein level in diet (25% CP) may result in sparing effect for high dietary protein (30%) with 4 CHO:L ratio.
