摘要
本文报道了湘西棘腹蛙人工饲养的初步结果.试验结果表明,成蛙的日食量平均为体重的4.47%;幼蛙的日食量平均为体重的4.86%.成蛙和幼蛙的饵料系数平均为4.1±0.1;蝌蚪的饵料系数平均为3.66.40～50克体重的幼蛙,平均日增重为2%.使用多成分混合性饵料饲养蝌蚪,其体长和体重增长显著.
The Preliminary results of artificially culturing Rana boulengeri in Western Hunan are reported in this paper. The experimental results show that the mean daily diet of adult frog(Rana boulengeri)is 4.47%, and 4.86% of young frog of body weight. The mean coefficient of bait of adult and young frog is 4.1±0.1; and that of tadpole (Rana boulengeri) is 3.66. The frogs being 40-50 grams, inerease 2% of their body weight daily. With multi-components food feeding tadpoles, the weight and length of tadpoles inerease notably.
