兴淮鲫的性腺发生和发育状况比较特殊，大致有下列类型；（１）无性腺个体，占解剖总数的１９．６％；（２）两性嵌合型个体，其性腺以卵巢为主，精巢为辅，占解剖总数的２．４５％；（３）卵巢发育不正常个体，占解剖总数的１９％；（４）卵巢发育正常个体，占解剖总数的１２．８％；（５）精巢发育异常个体，占解剖总数的１５．３％；（６）精巢发育正常个体，占解剖总数的３０．６％。总之，兴淮鲫的大多数个体性腺发育不正常，只有部分雌性和雄性个体的性腺发育是正常或比较正常的。但精巢内的精子是否具有受精能力尚待进一步研究。
The gonadal development and development status of Hokkai crucian carp is rather special. The following types are generally found: (1) gonadal individuals account for 19.6% of the total anatomy; (2) sex-chimeric individuals whose gonads are mainly ovary and testes Accounting for 2.45% of the total anatomy; (3) abnormal ovarian development of individuals, accounting for 19% of the total number of anatomical; (4) ovarian normal individuals, accounting for 12.8% of the total number of anatomical; Abnormal individuals, accounting for 15.3% of the total number of anatomical; (6) normal testes individuals, accounting for 30.6% of the total number of anatomies. In conclusion, most of the individual gonadal development in Carassius auratus is not normal, and only gonadal development in some females and males is normal or normal. However, whether or not the spermatozoa have fertilizing ability remains to be further studied.
