Abstract
The study investigated the effects of dietary fermented and autoclaved castor seed meal on growth performance, hematology and carcass composition of Clarias gariepinus fingerlings. 150 Clarias gariepinus fingerlings were randomly distributed into 5 groups of ten fish per tank each to five treatments. The experimental design is a complete randomise design in which there were three replicates for each treatment. The experimental diets which were designated 0%, 5%, 10%, 15% and 20% respectively were is-nitrogenous (42% Crude Protein content) and isocalorie meal was T3 (10%) inclusion as it gave the best WG (13.83g), SGR (1.31), RGR (1.34), and the lowest FCR (1.39) when compared with t2 (5%), t$(15%) and T5(20%). The lowest growth and feed utilisation parameters were observed in diet T5(20%). The carcass composition showed that crude protein and moisture of fish fed the control were significantly higher (p0.05) in control and CSM5 but were significantly (P
