ABSTRACT The effects of meal size on the postprandial metabolic response and of digestion on the post-exercise metabolic recovery process were investigated in juvenile black carp (Mylopharyngodon piceus) . Experimental fish were forcedly fed with compound feed (meal sizes: 0.5%, 1% and 2% body weight). Then, the postprandial oxygen consumption rate and excess post-exercise oxygen consumption (EPOC) of the experimental fish were measured. Both the duration and the peak of oxygen consumption rate (PMR) increased with increasing meal size. The peak post-exercise metabolic rate of digesting fish were significantly higher, whereas EPOC magnitude and its duration were significantly smaller or (shorter) than those in the fasting fish. It is suggested that (1) this fish fulfills the increased energy demand during the digestive process by increasing PMR and by prolonging SDA duration with increasing meal size and (2) digesting fish might decrease their anaerobic exhaustive activity but increase the post-exercise recovery capacity.

进餐量对青鱼（Mylopharyngodon piceus）餐后代谢反应和运动后代谢恢复过程的影响

摘要 在青鱼 (Mylopharyngodon piceus) 中研究了膳食量对餐后代谢反应和消化对运动后代谢恢复过程的影响。实验鱼强制饲喂配合饲料（饲料规格：体重的 0.5%、1% 和 2%）。然后，测量实验鱼的餐后耗氧率和运动后过量耗氧量（EPOC）。持续时间和耗氧率 (PMR) 峰值都随着膳食量的增加而增加。消化鱼的运动后代谢峰值显着高于禁食鱼，而 EPOC 的大小及其持续时间明显小于或（短）于空腹鱼。
