In order to determine the protein requirements of the Korean rockfish Sebastes schlegeli six isocaloric diets containing crude protein level from 20% to 60% were fed to two groups of fish, small and large size, with the initial average body weight of 8 g and 220 g respectively. White fish meal was used as a sole protein source. Daily weight gain, daily protein retention, daily energy retention, feed efficiency, protein retention efficiency and energy retention efficiency were significantly affected by the dietary protein content (p<0.05). The growth parameters (that is, daily weight gain, daily protein retention and daily energy retention) increased up to 44 % protein level with no additional response above this point. The protein requirements were determined from daily weight gain using two different mathematical models. Second order polynomial regression analysis showed that maximum daily weight gain occurred at 56.7 % and 50.6 % protein levels for the small size group and the large size group, respectively. However the protein requirements, determined by the broken line model, appeared to be about 40% for both groups. Nutrient utilization also suggested that the protein requirements of both groups were close to 40%. When daily protein intake was considered, daily protein requirements per 100 g of fish, estimated by the broken line model, were 0.99 g and 0.35 g for the small and large size groups respectively. Based on these results, a 40% dietary crude protein level could be recommended for the optimum growth and efficient nutrient utilization of the Korean rockfish weighing between 8 g and 300 g.
