摘　　要：为了研究光谱和温度协同对鱼类代谢作用,在水温15℃和20℃下,设置红、黄、绿、白4种LED光谱和遮光、自然光(光强≤100 lx)条件,测定鲈鲤Percocypris pingi幼鱼在静水中的日常耗氧率。结果显示,不同光谱组实验鱼日常耗氧率差异性显著(P<0.05),15℃时,红>黄>绿>白>自然光>遮光,20℃时,红>绿>自然光>黄>白>遮光;红光组显著高于其他组(P<0.05),遮光组显著小于其他组(P<0.05)。随着温度的升高,红、绿、黄、白、遮光和自然光组的日常平均耗氧率分别增加了27.94%、34.88%、17.33%、33.39%、40.63%和62.06%。耗氧率温度敏感系数表现为,自然光>遮光>绿>白>红>黄,LED色光(特别是黄光)暴露使鲈鲤幼鱼对温度的灵敏性降低。本研究结果为鲈鲤在不同的光照和温度条件下的代谢特性研究提供了基础资料,为其人工养殖光环境控制提供参考。Light and temperature have a profound impact on the growth,metabolism and locomotion of fish.In order to study the synergistic effect of light spectrum and temperature on fish metabolism,the routine oxygen consumption rate(RMR)of juvenile perch carp(Percocypris pingi)was measured at the temperature of 15℃and 20℃under red(R),yellow(Y),green(G)and white(W)LED spectrum(as well as covering and natural light)(light intensity≤100 lx),respec-tively.The results showed that the RMRs of fish in different spectrum groups were significantly different(P<0.05).At 15 oC and 20 oC,the sequence of RMR was R>Y>G>W>natural light>covering,and R>G>natural light>Y>W>covering,respectively.The RMR of R group was significantly higher than that of other groups(P<0.05),and the RMR of covering group was significantly lower than that of other groups(P<0.05).The RMRs under R,G,Y,and W LED spectrum,cov-ering,and natural light groups,increased by 27.94%,34.88%,17.33%,33.39%,40.63%and 62.06%with the tem-perature increasing from 15℃to 20℃,respectively.The temperature sensitivity coefficient(Q10)of RMR decreased un-der covering and different LED spectrum groups,and the sequence of Q10 was control>covering>G>W>R>Y.The tem-perature sensitivity of the juveniles decreased at different light spectrum exposures(specially,the yellow light).The study provides basic data for the metabolic characteristics of P.pingi under different light spectrum and temperatures,and the ref-erence for the control of artificial breeding light environment.
