Author(s): Ekta Singh, VP Saini and OP Sharma

Abstract: All male population, the red tilapia larvae which just finished the yolk sac were fed with feed containing 17 α Methyltestosterone at five different doses (0, 30, 40, 50 and 60 mgMT/kg feed) for 30 days, After 30 days, the fry were shifted to 15 cemented cisterns continued further for 4 months with commercial (Basal) feed for further growth and checking the sex ratio after sexual maturity under different treatments. It was found out that the sex reversal rates among the groups were at the levels of 40.0, 60.0, 76.67, 100.0 and 100.0%, respectively. Beside the highest male population in hormone treated fish, the growth of the fish was also higher in treatments than control. The oral application of hormone significantly increased male population as compared to control. The highest sex reversal rate was observed in the group to which 50 mgMT/kg feed dose was applied.
