The present study has been planned to evaluate the growth, body composition and fatty acid profile of genetically male tilapia (GMT) fingerlings fed four dietary oils supplemented diets as following treatments; 2% fish oil (FO, Control, T1), 2% soybean oil (SBO, T2), 2% sunflower oil (SFO, T3) and 2% canola oil (CO, T4) sprayed on commercial fish feed with 20% CP. The feeding trial was conducted in cemented rectangular tanks with the stocking of 100 fingerlings per tank, average weight 20 g and each tank having a biomass of 2 kg for a period of 120 days. The results indicated that maximum final weight was observed in T1 (fish oil) (158 ± 2.0 g), followed by T2 (soybean oil) (142.5 ± 2.5 g), T4 (canola oil) (116 ± 4 g) and minimum final weight in T3 (sunflower oil) (101.5 ± 3.5 g). Overall growth performance was found satisfactory. Muscle and liver fatty acid profiles reflected dietary fatty acid composition. It is suggested that dietary oils (soybean, sunflower and canola) can be used to substitute fish oil in commercial diets.
