摘要
对个体重２．５～８７．６ｇ的牙鲆幼鱼的代谢进行测试。结果表明：温度和体重对牙鲆幼鱼的耗氧率及二氧化碳排出率有明显的影响；牙鲆幼鱼的呼吸商为０．８２±０．０８，氧氮比为２３．８±６．６，其能源物质以蛋白质和脂肪为主；牙鲆在盐度为３０、２５、２０和１５的水中，平均代谢率分别为３．０８、３．０７、３．８７和３．２８Ｊ／ｇ·ｈ，说明牙鲆幼鱼适盐较广，在本实验盐度阈值内，对鱼体代谢基本没影响。
The metabolism of juvenile Janpanese flounder(indevadual body weight 2.5～87.6 g)was tested at different water temperatures and salinities.The oxygen consumption,CO 2 production and NH 3-N excretion rates of the fish were affected significantly by water temperature and body weight. The RQ and ratio of O/N of Japanese flounder were 0.82±0.08 and 24.4 ±6.4,which meants the energy metabolism of P. olivaceus was diminated by the oxidation of their their protein and lipid .Their mean metabolism rates at slainity 30,25,20,15 were 3.08,3.07,3.87,3.28 J/g·h, respectively,indicating Japanese flounder can adapt a wide range of salinity.
