Carcass proximate and amino acid composition of lyophilized bull and goat testes meal masculinized Clarias gariepinus was evaluated. Artificially bred Clarias gariepinus were masculinized, masculinization was carried out through feeding the fry with Lyophilized Bull Testes Meal (LBTM), Lyophilized Goat Testes Meal (LGTM) and commercial fish feed supplemented with Methyl Testosterone Hormone (MTH) as standard control for a period of four (4) weeks, at post juvenile stage, fish were fed commercial diet for five months. After five month of feeding, fish were anesthetized, gutted, freeze-dried and pulverized. Processed fish samples were stored in polythene bags for proximate and amino acid profile analyses. Proximate and amino acid composition of fish samples were determined following the standard methods of Association of Official Analytical Chemist (AOAC). Proximate and amino acid values of differently treated fish were subjected to one way Analysis of Variance (ANOVA) and Duncan Multiple Range Test (DMRT) was used to separate mean were significant. LBTM masculinized fish had the highest muscle tissue crude protein and amino acid composition while non-masculinized fish (control group) had the lowest crude protein and amino acid composition, in conclusion masculinization increased carcass quality with respect to carcass crude protein and essential amino acids.
