Abstrakt: The present study was conducted to study the effect of 17α-methyltestosterone (17α-MT) on masculinization efficiency through immersion treatment in dwarf gourami, Trichogaster lalius. The immersion treatment of 17α- MT at doses of 250, 500, 750 and 1000 μg/l was carried out for 3 h daily on third, fifth and eighth day after hatching. The highest concentrations of 17α-MT produced the highest percentage of males (84.29%). The progeny testing of males from17α-MT treated groups indicated that the female progenies of each of the males tested differ significantly from that of control, indicating that all those males carried XX genotype. The gonado-somatic index of the hormone treated fish revealed significant suppression of the ovarian development. [ABSTRACT FROM AUTHOR]
