Abstract

Astudy was undertaken to determine the effect of the dietary lipid levels on growth performance , feed utilization and body composition of Nile tilapia larvae. Four isonitrogenous diets (40% crude protein) and dietary lipid levels (4, 6, 8 and 10% DM) were fed to satiation Nile tilapia larvae for 9 weeks. The best survival, weight gain, specific growth rate (SGR), protein efficiency ratio (PER), feed conversion ratio (FCR) and feed efficiency were observed for larvae fed 8% lipid level. While the poorest survival, specific growth rate (SGR), protein efficiency ratio (PER), lowest weight gain, specific growth rate (SGR), feed efficiency and highest feed conversion ratio (FCR), were observed with larvae fed 4% lipid level. The lipid content of fish were positively correlated with dietary lipid level. The body protein content increased with increasing the protein levels in the diet. It could be concluded that the requirement of lipid for Nile tilapia fry was 8% lipid under the present experimental condition.
