Abstract:
The embryos of allogynogenetic crucian carp were soaked in testosterone propionate for 10～14 days,11.0％～13.6％ fry were induced to be physiological males and 10.5％～27.3％ fry developed into bisexual sterile.The 50-day old fish were fed diet containing methyltestosterone for 4 months and then reared for 182～335 days.More than 20％ fry developed into males.In addition,the ovaries in both sides of some treated fish were significantly different in size.
