摘要: 用丙酸睾丸素溶液浸泡行雌核发育的异育银鲫(Allogynogenetic crucian carp)胚胎10~14天,诱导出了11.0%~13.6%的雄性鱼和10.5%~27.3%的兼性鱼。对50日龄的异育银鲫幼鱼投喂甲基睾丸素4个月,再继续饲养182~335天,诱导出了20%以上的雄性鱼。此外,部分实验鱼两侧卵巢的大小出现明显差异。
Abstract:The embryos of allogynogenetic crucian carp were soaked in testosterone propionate for 10~14 days,11.0%~13.6% fry were induced to be physiological males and 10.5%~27.3% fry developed into bisexual sterile.The 50-day old fish were fed diet containing methyltestosterone for 4 months and then reared for 182~335 days.More than 20% fry developed into males.In addition,the ovaries in both sides of some treated fish were significantly different in size.
