中国林蛙南移养殖雌性诱变技术研究

当前中国林蛙的全人工养殖已经在我国各地兴起,中国林蛙南移养殖技术已取得重大突破,但性别比例失调问题严重,雌蛙和雄蛙的比例只有3:7,严重影响养殖效益,制约养蛙业的发展.为调整林蛙性别比例,分别在实验室内和浙江省新昌县新益生物科技有限公司中国林蛙养殖中心采用控温及在蝌蚪饵料中添加性激素双重调控方法,诱导性腺分化,达到了调整林蛙性别的目的,并对激素诱导的合适浓度和最佳时期进行了研究,使中国林蛙雌雄比例达到7:3.为促进中国林蛙南移养殖的发展提供了切实可行的雌性诱变技术.

A Study on Inducing Female Mutagenesis of Rana chensinensis Feed-in-south

At present,the artificial breeding of forest frog is thriving and the technology of feed-in-south have gained great advance. But the sexual imbalance was a serious problem(ratio of the female to the male was 3:7)and had great influenced on the benefits and the development of frog aquiculture. Both in laboratory and aquiculture center,two methods of temperature control and adding sexual hormone to tadpole forage were used to induce and regulate the development of frog sexual gland to adjust the sexual proportion and to achieve ideal result that the proportion of the female to the male was 7:3.The technology will accelerate the development of forest frog feed-in-south.
