摘　　要：本研究在室内环境条件下进行,研究了不同饥饿程度和再投喂后中国林蛙的生长变化,并对中国林蛙饥饿后的补偿生长及其机制进行了分析。结果表明:中国林蛙经饥饿后再投喂,各处理组的体重已经赶上对照组的体重,其体重逐渐增加,经单因素方差分析,对比变化不显著,呈现出完全补偿生长。体重恢复过程中,各饥饿处理组的特殊生长率(SGR)、摄食率(FR)及饵料转化率(CE)均存在不同程度的差异。The growth of Rana chensinensis David after starvation and refeeding under indoor environment were studied, and the effect of compensatory growth and its mechanism was analysed. The result showed that body weight was losing in term of starvation, and after recoveried feeding, all groups＇ body weight were increasing, but contrast with control group, there were no significant differences（ P 〉 0.05 ）. It was suggested that there were completely compensatory growth in all groups. However, there were many differences on SGR, FR, CE of different groups during weight recovery.
