Abstract

Casein-gelatin based iso-nitrogenous purified diets with graded levels of lipid (0,5,10,15, and 20 %) were fed to the fingerlings of Liza macrolepis for 60 days to evaluate the changes in growth, feed conversion and carcass composition. Absolute, relative and specific growth rates were found to be higher and FCR better in fishes receiving 5 % dietary lipid level. Carcass composition indicated that lipid, carbohydrate and ash were significantly different, while protein deposition was found to be not significantly varied from the initial values. The studies showed that a dietary lipid level of 5 % was optimal for the species for proper growth and feed conversion
