Abstract: The study intends to promote the use and marketing of agricultural, animal waste products with special emphasis on the production of maggot from faecal poultry droppings. This study therefore aims to determine the best level of supplementation of maggot with compounded ration, the rate of growth and nutrient utilization by Clarias gariepinus and the economic viability of feeding Clarias with the combination of maggot and compounded ration.Forty juvenile Clarias gariepinus of weight ranges between 100-120 gm were randomly allocated to four treatments (each of 10 juvenile Clarias gariepinus per hapa of 1�1�1 m) in a nursery pond with over flow supplied with bottom springing clean water. They are treatment 1 (100%) compounded ration of 35% crude protein), Treatment 2 (50% compounded ration+ 50% maggot), Treatment 3 (25% compounded ration+75% maggot), Treatment 4 (100% maggot) were set up for 7week experimental period. Growth performance was significantly (p<0.05) different among the 4 diet treatments with Treatment 2 (50% compounded ration+50% maggot) recording the highest Mean Weight Gain (MWG) (119.65 gm). Specific Growth Rate, (SGR) (1.303), Protein Eufficiency Ratio (PER) (0.3860), Daily Rate of Growth (DRG) (0.2442) but lowest Food Conversion Ratio (FCR) (5.9410). Ranking second is Treatment 1, third is Treatment 3, while the least growth performance of MWG (58.15 g) SGR (0.416). PER (0.2890), DRG (0.1187)and highest FCR (16.54) was recorded for Treatment 4, as the poorest diet. However the Crude Protein (CP) from proximate composition shows Treatment 4 with the highest CP of (63.31%) > Treatment 3 (54.65)> Treatment 2 (48.36%) > Treatment 1 (34.75%). This implies feeding maggot alone with fish (Treatment 4) will not supply the required protein quality (balance diet) that will supply at least 10 essential indispensable amino acids that is required for optimum growth. Hence a combination of compounded ration and maggot (Treatment 2) will meet this requirement and this will also yield the highest economic gain by reducing the cost of feed by 40% of the proposed total cost when compared with Treatment 1 and 2. High yield in terms of weight of fish, over 200% yield (double profit) on harvesting (Treatment 2) when compared with treatment 4 (100% maggot diet).
