棘胸蛙人工繁育新技术

The New Technology of the Rana spinosa David Artificial Propagation and Cultivation

在模拟棘胸蛙的野生态环境情况下,通过人工控制养殖池水的水温和酸碱度,根据棘胸蛙的生活特性,合理进行亲蛙选育、蝌蚪培育、幼蛙饲养和病害防治的技术改良,可以达到棘胸蛙年产卵次数达6～7次,年产卵量达1935粒,蛙卵孵化率达96.1%,蝌蚪变态率达96.5%,幼蛙成活率达96.8%的养殖效果。

We simulate the environment of the wild Rana Spinosa David,so that we can control temperature,basicity and acidity of the water.According to the living characteristic of Rana Spinosa David,we choose the parents of froggy,bring tadpole and little froggy up,make prevention of disease in improving technology rationally,the Rana Spinosa David can spawn 6~7 times with 1935 spawns every year,the frog incubation rate can reach as high as 96.1%,the tadpole metamorphosis rate 96.5%,the young frog survival rate 96.8%.
