[Effects of diets on growth, serum biochemical indices and lipid metabolism in Coilia nasus].

Effects of diets on growth, serum biochemical indices, and enzyme activities related to lipid metabolism in fingerlings Coilia nasus at age of 6 months were investigated during 60-day experiment in this study. Fingerlings with similar body length and mass were fed with one of 3 types of diets (diet 1: soft pellet; diet 2: soft pellet mixed with fish oil; diet 3: slow-sinking hard pellet). Fish fed with diets 2 or 3 had significantly higher total body mass, rate of mass gain, specific growth rate, and fullness coefficient than those fed with diet 1.
