研究了温度为15、20、25、30、35℃时豹纹鳃棘鲈幼鱼的代谢情况，并分析了幼鱼利用蛋白质、脂肪和糖类作为能源物质的供能情况。试验结果表明，在15～30℃范围内，各试验组耗氧率、排氨率和二氧化碳排出率均随温度的升高而升高，且差异显著（P＜0.05）；在15～30℃范围内，各试验组呼吸熵、氨熵、代谢率和排泄率均随温度的升高而升高，35℃时均下降。根据氧氮比的分析结果可知，豹纹鳃棘鲈幼鱼主要利用脂肪和蛋白质供能，且随着温度的升高，脂肪和碳水化合物供能的比例逐渐增大。Q10的变化规律反映出豹纹鳃棘鲈幼鱼的适温范围为15～30℃，且温度显著影响豹纹鳃棘鲈幼鱼的代谢率。

The metabolism of juvenilePlectropomus leopardusLacépèdewere measured at five different water temperatures (15,20,25,30,35℃), the energy contribution of lipid, protein and carbohydrate to the fish was also analyzed. The results show that oxygen consumption rates, ammonia excretion rates, carbon dioxide excretion rates increased with the water temperature rising from 15℃ to 30℃, and there were significant differences at different water temperature(P<0.05). Respiratory quotient, ammonia quotient, metabolic rates and excretion rates increased with the rise of temperature, and all decreased at 35℃. The results of oxygen-nitrogen ratio indicate that the juvenilePlectropomus leopardusLacépède utilized protein and fat as the major energy source. With temperature increasing, the proportion of fat and carbohydrate for the energy increased gradually. The change law ofQ10suggests that temperature between 15℃ and 30℃ was the optimum temperature for growth ofPlectropomus leopardusLacépède, and temperature influenced metabolic rates of juvenilePlectropomus leopardusLacépèdesignificantly.
