Abstract
This study was conducted to evaluate extruded pellet for the growth of grower Korean rockfish Sebastes schlegeli. Two replicate groups of 150 fish per each tank(initial mean weight 112 g) were fed one of four experimental extruded pellets for 8 months. Survival was 100% in all groups. Final mean weight, feed efficiency and protein efficiency ratio, feed intake and hepatosomatic index were not significantly different among all groups. Proximate compositions of the whole body and liver were not significantly different among all groups. It can be concluded that the dietary formulation used in four extruded pellets could be applied in the practical extruded pellet for grower Korean rockfish.
