On April 16, 1987, we found that there were two gonads that developed at the same time in the body of white crucian carp. The tail fish was 18 cm long (snout to the upper tail) with a body length of 15.3 cm, a height of 6.8 cm and a body weight of 119.2 g. Gonadal normal position, the ovary and the testes cross crowded together, testes in front of the ovary near the reproductive pores, part of the adhesion of fine ovarian adhesions, but can be separated. Ovary weight 8.26 grams, accounting for 6.9% of body weight, less than the maturity coefficient of normal mature females. Oval orange, can be separated, the majority of egg diameter has reached 1.20 ~
