【摘要】 对中国近海鲳属鱼类的肌浆蛋白酶（Ｐｍ）、酯酶（ＥＳＴ）、乳酸脱氢酶（ＬＤＨ）和超氧 化物歧化酶（ＳＯＤ）等生化特征作了比较分析。结果表明，中国鲳属鱼类的Ｐｍ，ＥＳＴ和ＳＯＤ 具有明显的种的特异性，而ＬＤＨ则无种间差异。青岛、上海、厦门和珠海４个取样地点银鲳 的Ｐｍ和ＥＳＴ酶谱完全相同，同样，上述４个取样地点的翎鲳Ｐｍ和ＥＳＴ酶谱也完全相同， 从生化学的角度证明了我国沿海鲳属鱼类存在５个种，并且所有海区的银鲳和翎鲳各为同 一个种。更多还原

【Abstract】 Pomfret fishes of the genus Pampus are widely distributed in Chinese coastal waters and the Indowest Pacific. About 158 fish specimens of 5 Pampus species were collected from Qingdao, Shanghai, Xiamen, Zhanjiang, Beihai and Zhuhai during the Period from November 1996 to April 1998. Zymogram characters of myogens, EST isozymes, LDH isozymes and SOD isozymes were examined by polyacrylamid gel method. The zymo- gram patterns of myogens, EST and SOD isozymes of Chinese pomfret fishes showed remarkable differences. LDH isozymes had no species specificity. There were no obvious differences in Pm and EST zymogram patterns among those populations of P. argenteus and P. punctatissimus collected from Qingdao, Shanghai, Xiamen and Zhuhai respectively. These results were consistent with those obtained by morphological method.更多还原
