Abstract

This study was conducted to evaluate the effects of replacing fish meal with sun-dried locust meal in the diet for Clarias gariepinus. Juveniles. Juveniles(20.0±0.02g) were stocked in improvised non-recirculatory and semi-flow through indoor plastic tanks (52x34x33cm) and fed diets (40% crude protein) containing sun-dried locust meal (SDLM) at levels of 0%, 25% 50% and 75% inclusion (Diets I, II, III and IV respectively) with two diets acting as control and reference (Diets (I and V). At the end of the 84 days feeding trials, diets with higher inclusion levels of SDLM (Diets III and IV) significantly depressed growth performance of fish. The variations observed in the Specific Growth Rate (SGR), Fed Conversion Ratio (FCR), Feed Efficiency Ratio (FER) and Protein Efficiency Ratio (PER) were associated with the chitin present in the diets, these parameters reduced with increasing levels of SDLM in the diets of fish. The results suggested that SDLM can be used to substitute up to 25% levels of dietary protein in C. gariepinus juveniles without significant reduction in growth.
