Author(s): Ekta Singh, OP Sharma, VP Saini, ML Ojha and HK Jain

Abstract: In the present study, optimum feeding rate of hormone (17α-MT) treated diet was evaluated in relation to higher male production and growth of fish. The present study was conducted for a total period of 6 months 2016. Initially for a period of one month the yolk sac observed fry was fed on hormone treated (@50 mg/kg) diet in glass aquaria and later for 5 months in cemented cisterns (3X3X1 m) for observing growth and sex ratio. For this purpose, four feeding rates, such as 10% (T1), 15% (T2), 20% (T3) and 25% (T4) were tested in triplicate. A control group without hormone treatment and 10% feeding rate was also used as control. The male population was significantly higher in treatments than control. As such the highest (100%) male population was noticed in T2, T3 and T4. In control it was only 60%. However, the weight gain was higher (1.86 g) in higher feeding rate of 15% body weight was found suitable.
