Juveniles of Nile tilapia were stocked (4.47 ± 0.26 g, eight fish per tank) and fed with test diets containing different inclusion levels of boiled Moringa oleifera leaf meal powder (0–30%: MLM 0, MLM 10, MLM 20, MLM 30), at 6% body weight for a total for six weeks. MLM 10 recorded the best average weight gain, specific growth rate, food conversion rate and protein efficiency ratio but there were no significance differences in all parameters with the MLM 30 diet which had the highest MLM inclusion. As there were no differences in fish growth and feed utilization between MLM 0 diet and MLM 10–30 diet, it would be possible to replace fish meal as a main dietary protein source by MLM up to 30% from 40% without any negative influence on the growth of juvenile Nile tilapia and is applicable as a practical rearing diet.
