dc.description.abstractThe aim of this work was to evaluate the effects of three different diameters of crumble diets (0.25, 0.35 and 0.50 on weight gain, growing, survival and sexual proportion to Nile tilapia (Oreochromis niloticus) larvae with 30, 60 and 90 days of age. In the first 30 days of age larvae were submitted to sex reversion with diets containing the hormone 17[alpha]-methyltestosterone in a dosage of 60mg/kg of ration, respecting the different diameters and after this period, larvae were measured, weighed and counted for calculation of survival taxes. For the biometrical parameters as weight total length a completely randomized design was used in subdivided installments with three treatments and repetitions, considering installments the three diameters of diet and the sub installments, the three ages. In the end of this study, fish fed with diets of grain diameters 0.35 and 0.25 mm obtained the best results for weight gain (14.42g and 13.36 g) and total length (83.13 mm and 82.72 mm), although these results were not statistically significant, and with grain diameters 0.50 and 0.35 mm resulted in 96,66 % and 93,33% of males, respectively, after histological an, of gonads, without statistics differences between the treatments.en
