This experiment was conducted for compare domestic experimental microparticulated diets with imported commercial microparticulated diets in olive flounder larvae, Paralichthys olivaceus (Temminck et Schlegel). Fish larve were fed four microparticulated diets from 8th day after hatching. Four diets were two commercial microparticulated diets D and H, and experimental microparticulated diets K1 and K2 formulated each with different protein sources (diet K1 ; squid meal, blood meal, yeast extract, chlorella powder, olive flounder muscle, Lys, and Met ; diet K2 ; whole egg protein, krill meal, short-necked clam meal, squid muscle, live yeast, yeast extract, and casein). There were no significant differences on body weight, body length and survival rates among four diet treatments up to the 40th day after hatching. At the 83th day after hatching, fish fed diet D had a significantly higher survival rate than that of fish fed diet K2, whereas there was no significant difference between to diet H and K1. Fish fed diet D had a significantly higher body weight than these of fish fed diaet K1 and K2, whereas there was no significant difference between fish fed diet D and H. There was no significant difference on EPA and DHA of body fatty acid composition among four diet treatments up to the 83th day after hatching. These results show that nutritionally well-ballanced domestic microparticulated diets for olive flouner lavae can be developed.
