中文摘要：

为了考查力竭训练对养殖鱼类生长能力和摄食代谢影响，在25℃条件下，测定了中华倒刺鲤（Spinibarbus sinensis）和岩原鲤（Procypris rabaudi）幼鱼各自非训练组和训练组（力竭追赶训练1次／d，历时21d）的生长参数和摄食代谢反应。结果显示：训练组中华倒刺钯幼鱼的摄食率、饲料转化效率、特定体重生长率、特定体长生长率、摄食代谢峰值、峰值比率、SDA总耗能量和SDA系数都显著小于非训练组；静止代谢率、SDA时间及峰值时间与非训练组无显著性差异。训练组岩原鲤幼鱼的饲料转化效率、特定体重生长率、特定体长生长率、静止代谢率和摄食代谢峰值都显著小于非训练组，但摄食率、SDA时间、峰值时间、峰值比率、SDA总耗能量和SDA系数与非训练组无显著性差异。研究表明：力竭训练导致两种鱼类的生长率都显著下降；在力竭训练条件下两种鱼类采用的摄食代谢适应策略不尽相同。

英文摘要：

To examine the effects of exhaustive chasing training on the growth performance and postprandial metabolic re- sponse of Spinibarbus sinensis and Procypris rabaudi, several growth parameters and postprandial metabolic rates were meas-ured on the non-trained and trained groups of two fish species at （25 ± 0. 5） %. Fish in the trained groups were performed exhaustive chasing training once daily for 21 days. Exhaustive chasing training resulted in significant decrease in feed in-take,feed conversion rate, wei6ht specific growth rate, length specific growth rate, the peak metabolic rates, the energy expended on specific dynamic action （SDA） and SDA coefficients compared with those of non-trained group in S. sinensis （P 〈 0. 05）. Resting metabolic rates, times of peak metabolic rate and durations of SDA were not significantly different between non-trained and trained groups in S. sinensls. Exhaustive chasing training elicited significant decrease in feed con- version rate, weight specific growth rate, length specific growth rate, resting metabolic rates and peak metabolic rates compared to those of the non-trained group in P. rabaudi （P 〈 0. 05 ）. However, feed intake, times of peak metabolic rate, durations of SDA, factorial metabolic scopes, the energy expended on SDA and SDA coefficients were not signifi-cantly different between the non-trained group and trained group in P. rabaudi. The results suggested that ： （ 1 ） The growth rates decreased significantly in S. sinensis and P. rabaudi by exhaustive chasing training. （2） S. sinensis and P. rabaudi a-dopt different feeding metabolic adaptation strategies under the condition of exhaustive chasing training.
