| Sumario: | The present work aimed to evaluate the productive performance of three Nile tilapia strains (O. niloticus) in the initial and of growth phases, in different stocking densities. The studied strains were Bouaké, Chitralada and GIFT. Five-hundred-liter tanks were used, testing nine treatments and three repetitions. The physical and chemical water parameters maintained normal conditions of cultivation for the species in both phases. In the initial phase, when comparing between the densities of the same strain, no differences were identified in Chitralada. However, the Bouaké and GIFT strains reflected sensibility to the increase in stocking densities. In the growth phase, the results obtained for the parameters of final medium performance indicate differences (p < 0.05) between the appraised densities within the same strain. However, when compared to the same densities between the different strains, significant differences were not observed. No best performance was observed for any of the strains studied in function of stocking density |
