| 摘 要： | 用方正银鲫()×镜鲤()所产生的全雌性后代的一部份幼鱼,投以95％酒精作性诱导剂的配制饲料,使幼鱼性转化为生理雄鱼。转化率在84％以上。此法开始处理的时间是在孵化后16—17天,处理的持续时间为30—40天。3年来,从性转化的生理雄鱼与方正银鲫雌鱼获得了无性生殖系一代,然后再从此一代获得了无性生殖系二代,以此建立了方正银鲫纯系。根据后代形态学指标、染色体数和红血球体积等确定,后代与亲本完全相似,并由此确定方正银鲫的性别决定机制,雌性为XX型,雄性为XY型。

| Abstract: | All female young fish, which were produced by mating cruciancarp (Carassius auratus gibelio block)() with common carp (Cyprinus carpio)(scattered) were daily fed on the diet mixed with 95% alcohol (one ml per gramof diet as sex inductive anbstance and 84% of the fish developed into males (sexreversal physiological males). The treatment begun on 16-17 days after hatchingand continued for 30-40 days. After 3 years experiments we got the first asexualgeneration from mating the reversal males with female crucian carp. And then madethe reversal males mate with the first asexual generation, we obtained the secondasexual generation which may be called pure-clonic form of crucian carp. Accordingto the index of morphological characters, numbers of chromosome and the volume ofred cel1, the pureclonic form is not different from crucian carp. Besides, the mecha-nism of sex determination has been found XX ();XY (). |
