用类固醇成功地控制鱼类性别已有许多文章报道:如青鳉、鲫、黑鲷、虹鳉、罗非鱼、硬头鳟、银大麻哈鱼、溪红点鲑等.由于降海鳗鱼的捕获量很少,养殖的鳗鱼雌体比例又很低(仅3.5%),致使用于繁殖幼鳗的日本鳗鲡怀卵种群奇缺.尽管如此,至今还不曾有报道成功控制鳗鱼性别的文章.为获得更多的雌体,这就需要研究控制鳗鱼性别的技术.

However, no article has so far been reported on the successful control of eel sex. In order to get more female body, which requires research on the control of eel sex.
