A feeding experiment was conducted to determine the effects of feeding frequency on growth and body composition in juvenile olive flounder (Paralichthys olivaceus). Triplicate groups of the 40 fish averaging 1.6 g were fed the 2 different commercial diets (D-1 and D-2) and moist pellet (MP) contained frozen horse mackerel and commercial binder meal at different feeding frequencies of 4 times daily, 3 times daily, 2 times daily, once a day or once in 2 days. Growth and feed intake of fish were affected by diets and feeding frequencies (P<0.05). Feed intake ($\%$ of body wt.) in the all diet groups was significantly decreased according to feeding frequency decreased (P<0.05). Weight gain of fish fed the each diet were increased according to feeding frequency increased, although no significant differences were observed between 3 times and 4 times daily (P>0,05). If the same feeding frequency, feed intake and growth of fish fed the moist pellet were lower (P<0.05) than those of commercial diets (D-1 or D-2), probably due to the relatively high moisture content or unbalanced nutrients. Whole body lipid content of fish fed the each diet at once in 2 days was the lowest among feeding frequencies. These results indicate that 3 times daily feeding regimen may be more effective than that of 4 times daily and moist pellet in this study will not be used as a practical type of diet for juvenile olive flounder weighing between 1,6 g and 4 g.
