Abstract
Casein-gelatin based isocaloric purified diets with graded levels of protein (10-60%)
were fed to the fingerlings of Liza macrolepis for 60 days to evaluate the growth, feed
conversion and carcass composition. Relative growth, specific growth, normalized biomass
index and survival rate were higher and feed conversion ratio, lower in fish which received
40% dietary protein. Carcass composition of the fish indicated that protein, lipid,
carbohydrate and moisture were significantly different while ash content was not
significantly different from the initial values. The studies showed that dietary protein at
a level of 40% was optimal for the species.
