In order to promote the feed production of Tilapia in Senegal, three diets were produced from animal raw materials, agricultural by-products and spirulina at rates of 0%, 17%, and 32 %. In order to evaluate their effects on growth performance, survival, feed efficiency and carcass composition , three diets were composed of 25% protein and 8.62% lipid R1, 30% protein and 8.31% lipids R2 and 35% protein and 8.62% lipids R3. A total of 60 hybrid red Tilapia fry with an initial mean weight of 0.6 g were distributed in an isolated system consisting of 80-liter plastic tanks with a density of 10 fish per tank. The present study was carried out at the Ouakam hatchery. After 8 weeks of experimentation, the results revealed that for all treatments studied, the mean temperature was around 23.94°C. The final mean weight varied between 1.41 g and 3.29 g according to the treatments. The best growth parameters and feed efficiency studied, such as absolute mean weight gain, relative mean weight gain, specific growth rate, daily individual growth, feed conversion rate and protein efficiency rate were obtained in the diet R3 composed of 35% protein and 32% spirulina. The best survival rate 97% was recorded at control diet R1 containing 0% spirulina.The protein content of the carcass is higher in fish subjected to the different R1 (59.77), R2 (60.24), R3 (60.77) diets than in the initial fish (48.64). The fat content of the initial fish recorded the highest rate (33.83) compared to the R1, R2, R3 diets respectively 26.54, 23.36 and 24.79 which decreased. Finally, for the dry matter content, it increased slightly in the experimental diets R2 (96.55) R3 (96.50), except for the diet R1 (94.93) which recorded a lower rate than the initial fish (95.37). Results obtained at the end of this study suggest that spirulina can supplemented with fish meal in diet of hybrid red tilapia fry.
