| 摘 要： | 在(21.0±1.0)℃水温范围下,对金鱼采取了不同饥饿时间处理及再投喂实验,测定其主要生长指标,探讨其补偿生长情况和机制.实验结果表明,金鱼的补偿生长的类型属于完全补偿生长.从摄食率和食物转化率的测定来看,饥饿恢复投喂后金鱼既增加了摄食量又提高了食物转化率.短时间(5d)的饥饿后恢复投喂,金鱼主要以增加摄食量为主;长...

| Abstract: | At temperature of（21 ± 1 ） ℃, the trial was carried on goldfish by different starvation and re - feed time, in order to investigate the compensatory and its mechanism. The results showed that the type of the compensatory growth is completely compensatory growth . For goldfish,higher specific growth rates were obtained from higher feeding rate and higher food conversion. When the starvation time is short （5 d）, the com- pensatory growth resulted from higher feeding d）, the compensatory growth resulted rate. However,when the starvation time is relatively long （10 or 15 mostly from higher food conversion. |
