牙鲆是我国重要的海水养殖鱼类。因为雌性比雄性个体大、生长快，所以养殖雌鱼饲养周期短，经济效益高。要达到雌性单性化养殖，可以通过人工控制性别途径实现。针对目前全雌牙鲆生产过程中采用的3种方法———外源激素处理、养殖温度控制和人工诱导雌核发育，本文依据牙鲆性别分化机制，分别综述了它们的作用机理、优缺点及存在问题，为全雌牙鲆的科学养殖提供参考。
牙鲆是我國重要的海水養殖魚類。因為雌性比雄性箇體大、生長快，所以養殖雌魚飼養週期短，經濟效益高。要達到雌性單性化養殖，可以通過人工控製性彆途徑實現。針對目前全雌牙鲆生產過程中採用的3種方法———外源激素處理、養殖溫度控製和人工誘導雌覈髮育，本文依據牙鲆性彆分化機製，分彆綜述瞭它們的作用機理、優缺點及存在問題，為全雌牙鲆的科學養殖提供參攷。

Japanese flounder ( Paralichthys oliv aceus ) is a commercially important marine finfish in China .The growth rate of Japanese flounder is significantly faster in female than that in male ,so the feminized culture of Japanese flounder by artificial manipulation can shorten breeding cycle ,improve aquaculture production ,and now is considered economically very important .Based on the mechanism of sex -differentiation of Japanese flounder ,this paper review ed the mechanism ,precautions ,advantages and disadvantages in exogenous hormone treatment ,temperature control and gynogenetic inducement in this species for all-female population construction .Meanwhile ,future research and development on all female flounder has been elaborated .
