A feeding trial was carried out to investigate the effect of different fish meal and wheat flour contents in extruded pellets on the growth and apparent nutrient digestibility of olive flounder Paralichthys olivaceus. Four extruded pellets (HB1, HB1T, HB2 and HB2T) were prepared using two kinds of high quality brown fish meal and low quality tuna fish meal. Two diets (HB1 and HB2) contained two different kinds of brown fish meal, respectively; in HB1T and HB2T, we substituted 50 % of the brown fish meal with 10 % wheat flour. Three replicate groups of fish (initial body weight of 82 g) were fed the experimental pellets to visual satiation for 15 weeks. The highest weight gain was observed in fish fed HB1, and weight gain of fish fed HB2 was significantly higher than that of fish fed HB2T (P<0.05). Feeding efficiency for fish fed HB1 was significantly higher than that of fish fed HB1T and HB2T (P<0.05), but was not significantly different from fish fed HB2. Apparent dry matter digestibility in HB1 and HB2 was significantly higher than in HB1T and HB2T (P<0.05). The highest crude protein digestibility was observed in HB1, and protein digestibility in HB1T and HB2 was higher than in HB2T (P<0.05). The results of this study suggest that fish meal quality considerably affects growth and nutrient digestibility of olive flounder fed extruded pellets, and the use of HB1 is recommended over HB1T, HB2 and HB2T for efficient olive flounder production.
