viiiAbstractThe production of Nile tilapia Oreochromis niloticus tends to use high stockingdensities in all stages of cultivation, suggesting the need for improving the managementand strategies to increase the productivity of the species and minimize barriers still exist. Inthis context, this paper presents a literature review on factors influencing the performanceof Nile tilapia during the sexual induction phase, in particular, studies that observed theinfluence of density and availability of dietary vitamin C on growth, variability growth andsurvival of post-larvae at the stage of sex induction. Then, it presents a scientific paper thatreports a study aimed to evaluate the effect of density and vitamin C supplementation inthe diet on the growth of post-larvae of Nile tilapia, from sexual induction. Among theresults is how does the influence of the factors analyzed in the performance of the species.The study concluded that the interaction between density and vitamin C supplementationdid not influence the variability of growth and stress resistance of post-larvae in sexualinduction. But influenced the weight where the density factor was responsible for thedifference throughout the experiment and the factor supplementation of vitamin C at theend of the experiment.Key words: heterogeneous growth, nutrition, Oreochromis niloticus, sex induction, stress
