Effective method for sex reversal by means of hormaonal treatment was investigated. Critical period for sex reversal was confirmed. Sex reversal in carp, ayu, tilapia, pejerrey and coregonus was succeeded. Effective hormones were estradiol-17 B and methyl-testosterone. The former evoked feminization and the later masculinization. Orally administerd steroid was accumulated in the liver and gall bladder and excrined within 1.5-3 hours after administration. Therefore, the safty as the food was seemed to be quite enough when administered during larval or juvenile stage.

探讨了激素治疗性逆转的有效方法。确定了性逆转的关键期。在鲤鱼、阿玉、罗非鱼、鲫鱼和梭子鱼中成功地进行了性别反转。有效的激素是雌二醇- 17b和甲基睾酮。前者引起女性化，后者引起男性化。口服类固醇积聚在肝脏和胆囊，并在给药后1.5-3小时内检查。因此，在幼虫期或幼年期给药时，作为食物的安全性似乎是足够的。
