The production of all-male populations in cichlid fish, is crucial to obtain high yielding in fish farming. The aim of this paper was to determinate the optimal dose and time of exposure to fluoxymesterone (FM), during the masculinization of Mayan cichlid Cichlasoma urophthalmus larvae. Therefore, two periods of exposure to FM (45 and 60 days) and four androgen doses (0, 15, 30 and 60mg/kg of food) were tested, having a total of five treatments with FM (15mg 60d, 30mg 45d, 30mg 60d, 60mg 45d and 60mg 60d) and one control group (0mg 60d, CTL), in triplicate. One kilogram of Purina tilapia starter feed (45% protein) was sprayed with a hormone solution previously dissolved in ethyl alcohol, according to each separate testing dose mentioned abo...
