Abstract: The present study was performed to investigate the effect of dietary protein sources on the growth performance, nutrient efficiency and biochemical body composition in Heterotis niloticus fingerlings. Five experimental diets were formulated to contain three sources of protein: diet D1 (based on fishmeal), diet D2 (based on earthworm meal), diet D3 (based on maggot meal). In diets D4 and D5, the proportion of fish meal was half replaced by earthworm and maggot meal, respectively.Fish with an initial body weight of 160.02 ± 18.60 g were fed with the experimental diets in triplicate groups per treatment.No significant difference was found on Final body weight (FBW), Specific growth rate (SGR), feed conversion ratio (FCR) and whole-body composition between fish fed with diet D4 and the control group that fed with a reference diet (D1) after 54 days. In view of growth performance, it appeared that earthworm meal could partly replace fishmeal in the diet of H. niloticus fingerlings.
