Abstract The effect of Moringa oleifera leaf powder on the organosomatic index (gill, kidney, liver, heart and spleen), condition factor and glucose profile was carefully examined in this study. It was observed that the responses of Clarias gariepinus juveniles (mean length, 29.8±1.40cm SD; mean weight, 203.3± 5.11g SD g) exposed to 0.05, 0.10, 0.15 and 0.20g/l of Moringa Oleifera leaf powder for 15 days was concentration dependent. Fish gill recorded the highest index at 0.20g/l (24.55%) and least at 0.05g/l (17.42%) when compared with control (19.57%). Gill, kidney and spleen indices at 0.05, 0.10, 0.15 and 0.20g/l and condition factor were not significantly impacted (P>0.05) while liver and heart were significantly impacted (P<0.05) with increase in M. oleifera leaf concentration when compared with control. Glucose level was significantly (P<0.05) impacted at all the treatment levels when compared with control. The study indicated that the phytochemicals in Moringa oleifera leaf could improve the health status or well being and influence positively on the utilization of energy derived from glucose for other necessary use in fish body.
