Abstract: 

This study was conducted to evaluate the effect of six hormonal doses 30, 60, 100, 150, 200 & 300 mg 17 alpha-methyl testosterone (MT) /kg food diet on the mortality rate of Convict Cichlid, Cichlasoma nigrofasciatum, and Guppy Poecilia reticulata, using validated microscopic examination of the gonads and sex determination of the fish. Cichlid fry (7day) and Guppy fry (1day) received the following diets for 40 days. The frequency data of fish mortality rate after treatments and microscopic characteristic showed with percent, obtained data of treatments was higher than the control groups, and a dose of 300 mg MT/kg food in Convict Cichlid was more efficient in mortality rate, resulting in 37.5% (P<0.05), and a dose of 300 mg MT/kg food in Guppy was more efficient in mortality rate, resulting in 46.6% (P<0.05).
