摘要
1986～1990年用甲基睾丸酮、乙烯雌酚诱导黄鳝性转化,结果表明:甲基睾丸酮12.5mg处理胚后期的黄鳝,一年后有的幼鳝的卵巢已完全转变为精巢,精子多而且活动激烈;25mg处理胚后期,饲养4个月,有幼鳝转变为雄鳝,并与同池中雌鳝自产仔鳝,大大缩短了雄鳝的性成熟年龄。乙烯雌酚可使产卵后的雌鳝推迟性逆转期,使未产卵的雌鳝生长加快、体重增加、增加怀卵量、多产鳝苗。
A experiment of induction on sex reversal of Monopterus albus using herterogenous hormones was conducted during 1986-1990.The results showed that the postembryonic eels were soaked in the methyltestosterone (MT) solution in four concentrations, 50, 25, 12.5 and 6.3mg per tail. In the 12.5mg diet, the gonad of two young eels were developed into testis from ovary after one year and had a number of sperms with vigorous motility. In the 25mg MT diet, a part of young eels were turned to males and mated up with the female ones in the same pond, 35 fries were produced. This hormone could shorten the age of sex maturity of males. By injection of diethylstilbestrol, the sex reversal stage of field eel after deposit could be put off and sped up the growth, increased the body weight and improved the fecundity for the female eels before deposit.
