Effect of six diets having two lipid levels and three crude protein levels on growth and fillet composition of Genetically Improved Farmed Tilapia (GIFT) reared in cages was evaluated. Diets having Crude Protein levels (CP) 26%, 30% and 36% and Crude Fat levels (CF) (7% and 12%) were formulated. Experiment was set up according to 3 X 2 factorial designs. GIFT fingerlings (2.94 ± 1.47g) were stocked at a density of 75 fish /m-3 in net cages each having a water volume of 2 m3. Fish in quadruplicated treatments were fed with six diets for 150 days. Fish fed with 36% CP diets had significantly different (P≤0.05) values for all growth indices; Final Mean Weight, Specific Growth Rate, Feed Conversion Ratio and Net Yield while no such difference found between 26% CP and 30% CP diets for the same growth indices.
