Abstract
This study was conducted to determine the effects of the dietary microbial phytase (P) supplementation on growth performance and bioavailability of phosphorus in juvenile olive flounder, Paralichthys olivaceus and juvenile Korean rockfish, Sebastes schlegeli fed soybean meal-based diets. Nine experimental diets were formulated to be isonitrogenous and isocalolic to contain 50.0%crude protein (CP) and 16.7kJ, 48.6% crude protein (CP) and 16.0kJ available energy/g without the dietary phytase supplementation for olive flounder and Korean rockfish, respectively : 100% fish meal (FM); 70% FM + 30% soybean meal (SM); 70% FM + 30% SM + Phytase(P) 1000U/kg diet; 70% FM + 30% SM + P 2000U/kg diet; 70% FM + 30% SM with phytase-treated (Ptre) P 1000U/kg diet; 60% FM + 40% SM; 60% FM + 40% SM + P 1000U/kg diet; 60% FM + 40% SM + P 2000U/kg diet; 60% PM + 40% SM with Ptre P 1000U/kg diet. After two weeks of the conditioning period, triplicate groups of 25 fish initially averaging 6.15
