摘　　要：有些水生经济动物具有明显的性别二态性,这种特性与养殖品质、商业价值具有一定的相关性。然而,大多数水生动物不具有明显的性征,在育种时难以识别亲本性别,导致额外的劳动力和培育成本增加。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性别决定基因,以期为水生动物种质资源保护和良种选育提供理论参考。Several economically important aquatic animals exhibit sexual dimorphism.These properties are relevant to their aquacultural and commercial value.However,most aquatic animals do not have obvious sex characteristics.It is difficult to identify the sex of the parents in an aquaculture operation,which subsequently generates extra labor and cultivation costs.This study reviews sexual dimorphism,common sex identification methods,and sex-determining genes in economically important aquatic animals.These methods may be useful for providing theoretical support for the protection of germplasm resources and the cultivation of improved varieties.
