摘　　要：[目的]了解半滑舌鳎性逆转的生理发育过程。[方法]对5个家系的半滑舌鳎进行性腺发育的组织学观察、遗传性别鉴定和生理性别分析。[结果]半滑舌鳎性逆转有着明显的群体性,性逆转只发生在特定群体中,有些群体完全不逆转;半滑舌鳎发生逆转的遗传雌鱼在性腺发育过程中,会出现明显的兼性阶段,即雌雄兼有的特有过程。[结论]该研究结果可为剖析半滑舌鳎性逆转的分子、生理机理以及性逆转遗传因子的作用机理提供研究方向和研究线索。[ Objective] To better understand the physiological development of the sex-reversal of Cynoglossus semilaevis.[ Method] This study focus on the observation of gonadal development histologically among five families of Cynoglossus semilaevis, the genetic-sex identification and the analysis for physiological sex.[Result] The sex-reversal only occurs among the specific population which characterized with population, no sex-reversal occurs among some particular population;There exists a particular obvious chimeric stage, which is a stage while the female and male gonadal cells coexist.[Conclusion] The above founds will give light for the future research on molecularly, physiologically mechanisms of the sex-reversal of Cynoglossus semilaevis, even the action mode with the genetically factors of the sex-reversal.
