| 摘要: |
| 部分水生经济动物具有性别二态性，这种特性与养殖品质、商业价值相关。与哺乳动物不同，水生动物不具有明显的性征，在育种时难以识别亲本性别，会造成额外的劳动力和培育成本。该文主要围绕水生经济动物性别遗传基础及其鉴定方式，综述了水生经济动物的性别二态现象、常见的性别鉴定方式以及决定基因，以期为种质资源保护和良种选育提供理论参考。 |

| Abstract: |
| Many aquatic economic animals have sex dimorphism. These properties are related to aquaculture quality and commercial value. Different from mammals, aquatic animals do not have obvious sexual characteristics. It is difficult to identify the gender of the parents in the aquaculture production. This creates extra labor and cultivation costs. This paper reviews the sexual dimorphism, common sex identification methods and sex-determining genes of aquatic economic animals, which are used for providing theoretical support for the protection of germplasm resources and the cultivation of improved varieties. |
