dc.description.abstract | : The results clearly indicate that final body weight, weight gain, specific growth rate and feed efficiency of fish fed one to two meals per day were significantly (P<0.05) higher than those of fish fed one meal every 2 days and three meals per day. The feed intake of fish fed one meal every 2 days was significantly (P<0.05) lower than those of fish fed one to three meals per day. The inter-individual size variation in weight was not significantly (P>0.05) affected by feeding frequency. The maximum feed intake of fish appeared at the first meal and last meal of each treatment but the magnitude of consumed feeds changed with feeding frequency. The concentration of hematocrit, GOT (glutamic oxaloacetic transaminase) and GPT (glutamic pyruvic transaminase) were not significantly (P>0.05) affected by feeding frequency. The glucose concentration of fish fed one meal every 2 days was significantly (P<0.05) higher than those of fish fed one to three meals per day. The concentrations of TCHO (total cholesterol) and HDLC (high density of lipoprotein cholesterol) of fish fed one and two meals per day were significantly (P<0.05) higher than those of fish fed one meal every 2 days and three meals per day. We conclude that the optimum feeding frequency aimed at optimized growth of Korean rock bream weighing from 100 to 200 g reared in sea cages is two meals per day under our experimental conditions including particular diet and s per day.
