The objectives of the present study were to compare the efficiency of two diets: 1 (NUTRAVIT) and 2 (IP), both with 40% of crude protein, containing the synthetic androgen hormone 17 a-methyltestosterone (MT) and to analyze the most effective dose of this hormone on the sex reversal of Nile tilapia Oreochromis niloticus, throughout histological analysis of the gonads and sex determination of the samples. A total of 9600 Nile tilapia fries with seven days posthatching received the following treatments, per […]
