摘  要:
对美国金鳟在9.0℃水温下进行了不同饥饿时间处理再投喂试验。试验共进行42d。试验结果显示:饥饿7d再投喂35d其体重增量超过了对照组,具有超补偿生长能力;饥饿14d、21d再分别投喂28d、21d,其体重增量均未超过对照组,但投喂后生长速度明显快于对照组,具有部分补偿生长能力。我们分析饥饿7d组鱼是靠提高了摄食量和食物转化率共同实现超补偿生长的;饥饿14d组和饥饿21d组鱼是通过提高食物转化率实现部分补偿生长的。

摘  要:
the study was conducted to reval the ability of compensatory growth after food deprivation and refeeding ofOneorbynchus mykiss.In temperature of 9.0℃.Within the 42 days of experiment.It was increasing more the depriving group weight of 7 days than that of contrast.There had over-compensatory growth for the food depriving group of 7 days.Others group weight did not to increasing the contrast,but other fishes growth more faster than the contrast fishes.It was partially compensatory growth.The results suggest that the mechanismin of compensatory growth was different.the group of hungry 7 days was due to the low oxygen consumption rate and high digestion and Absorption after starvation and high total feeding quantity.But others hungry groups only due to the high digestion and Absorption after starvation.
