Abstract
Male-population of Tilapia nilotica was produced with 17aethynyltestosterone at 60ug/g diet. Subsequently fry were fed
1.2,3,4 and 5 g/kg active yeast diet for 70 days. Fish fed on dietary yeast were significantly heavier than the control. The percentage of males was 62.1. Ovotestis condition was found. Histological anomalies of the gonads of both sexes have been observed.Sterilization of the testis was complete at all levels of yeast diet.Dietary treatment had a destructive effect on the histological appearance of gonadal development.
