A feeding experiment was conducted to investigate the effects of deletion of P, Ca, Zn, Mg, Fe, K, Mn, or Se from mineral premix in the diets containing $40\%$ fish meal on growth performance of juvenile Korean rockfish. Three replicate groups of the fish initially averaging 5.4 g were fed the experimental diets deleted one ot each mineral (P, Ca, Zn, Mg, Fe, K, Mn, Se or all) in the mineral premix for 9 weeks. A basal diet with fish meal ($40\%$), meat meal ($9\%$), soybean meal ($5\%$), corngluten meal ($3\%$), and leather meal ($3\%$) as protein sources were included. Weight gain in fish fed diets deleted Ca, Zn, K, or Se was lower than that of control diet ( P0.05). Apparent skeletal deformities were not observed in the diets deleted each mineral, The data obtained in this study indicate that each of the Ca, Zn, K, or Se should be added in the diet contained $40\%$ fish meal for normal growth of Korean rockfish.
