This study evaluates the nutrient utilization and growth performance of African catfish (Clarias gariepinus) fed alternative animal protein composite meal for 42 days. The composite meal is composed of feather meal, blood meal, tilapia meal, and maggot meal each in a 25% proportion. Five isonitrogenous diets (T1, T2, T3, T4, and T5) containing 40% crude protein were formulated with the composite meal replacing fish meal at 0% control (T1), 25% (T2), 50% (T3), 75% (T4) and 100%(T5) respectively. The weight gain, protein intake, protein efficiency ratio, and specific growth rate in the 75% and 100% inclusion levels were not significantly different from the control diet. Fish survival ranged between 90-95% with the highest weight gain of 10.57g observed in the 100% inclusion level. The Feed conversion ratio varied between (1.17 and 1.37). The results from growth, feed utilization, and survival levels showed an overall good growth of the fish in the experimental diets, and this indicates that the composite meal is a potential replacement for fish meal in the diets of Clarias gariepinus fingerlings.
