Partial replacement of fish meal by Moringa leaf meal was conducted in 56 days at theBiological garden of Federal University of Kashere. Four diets(40% crude protein ) including thecontrol (Diet A), Diet B, Diet C and Diet D with an inclusion level of 0%, 10%, 20% and 30%respectively based on fish meal were formulated and tested on Clarias gariepinus. These dietswere tested on duplicates of 10 fishes of initial weight of 2.4g±0.07 per bowl. The resultobtained showed that there is no significant difference (p>0.05) in final weight gain of fishes fedthe control diet (Diet A) and 30% replacement (Diet D). But there was significant difference incontrol diet and diet B and C. The highest mean weight gain 6.07±0.28g was recorded in fishesfed the control diet while the lowest 2.28±0.21g was recorded in 10% inclusion level. Thehighest final mean length 10.00±0.12 cm was obtained from fishes fed the control diet while thelowest 8.09±0.20cm was obtained from fishes fed 10% inclusion level. The carcass compositionwas recorded with the highest protein value of 48.31% recorded in Diet D and the lowest 32.28%in Diet A. This study showed that Moringa oleifera leaves can replace 30% of the fish mealcomponent for African catfish without any adverse effects on growth. However, more studyshould be done in finding methods for inactivating the antinutritional factors for inclusion ofMoringa leaves in the diet of African catfish at higher levels.
