The study investigated the effect of Moringa oleifera leaf meal diets on the liver size, intestine length and the robustness of Clarias gariepinus.This was done to fill the knowledge gap on the effect of this leaf on the liver, intestine and condition factor of C.oleifera.The information obtained will help to reduce cost of feeding in the culture of this fish. M. oleifera leaf meal substituted fish meal at 0% (control), 30% (raw) and 30% (steam heated) in\n the three different diets. A total of 180 C. gariepinus fingerlings (mean weight 9.60 + 0.06) were randomly distributed into Nine plastic aquaria tanks at 20 fish per tank in triplicate treatments and were fed twice daily at 9.00 hrs and 17.00 hrs for 12 weeks. The results showed that hepatosomatic indices were not significantly different (p >0.05) while those fed with 30% steam heated M. oleifera had highest intestine length and was significant (p < 0.05). The condition factor was 1.00, 0.94 and 0.92 for 0% (control), 30% (steam heated) and 30% (raw) respectively. The study showed that M.oleifera leaf meal has good potential for use as fish meal substitute in C. gariepinus diet since it does not have significant negative effect on the liver, intestine and the condition of the fish. Also, it was shown that the processed M. oleifera leaf meal provided better condition than the raw M.oleifera leaf meal.
