【Abstract】 study on the induction of sex reversal in the grouper,Epinephelus tauvina (Forskal), a protogynous hermaphrodite, was conducted by using androgen-implantation method. The mature females of 3-7 years of age were transformed into functional males in a period about 50-90 days, which were used for artificial reproduction with females in the contrast group of the experiment, producing successfully more than 80 thousands normal and viable larvae. The gonadosomatic index of the androgen-treatment fish group was obviously smaller than that of the contrast fish group, being only about 1/29.The development and transformation process of gonad and sex cells and some effects of androgen on the fish during the period of sex transformation were discussed in the paper.更多还原
