Abstract

The chemical compositions of Tilapia mosambis fish from major dams in Ekiti State were analysed. The proximate analysis shows that the protein content (69.70 to 79.56%) of the fish sample was very high as well as the organic matter (92.03 to 96.15%). The sample was low in Zn, Fe, Pb, and Mn but slightly high in Na, K, Mg and Ca. The total amino acid was 920.5 to 956.1 mg/g crude protein while the essential amino acid was 379.5 to 433.8 mg/g crude protein. The amino acid scores ranged between 0.45 to 2.0 showing leucine to be the limiting amino acid. The results show that fish sample is a good source of protein.
