摘　　要：采集东海区黄鳍马面 (Thamnaconushypargyreus) 7批样本共 56 0尾 ,南海区 4批样本共 330尾 ,用均数差异显著性检验、判别函数以及等级聚类分析等数值分析方法 ,对其第二背鳍、臀鳍、左右胸鳍等计数性状和头长 /体长、头长 /体高、体高 /体长等量度性状进行检验和分析 ,并结合生态系方法对两海区的种群进行分析研究。结果表明 ,东海与南海的黄鳍马面为 2个种群 ,称之为东海种群和南海种群 ,并提出了东海种群资源的管理意见。Thamnaconus hypargyreus has been an important fishing object of trawl fishing in the East China Sea and the South China Sea recent years, but the information on its populations is unknown yet. During June 1994 to July 1996, 7 batches of T. hypargyreus samples (560 inds) from the East China Sea and 4 batches (330 inds) from the South China Sea were collected. Some methods, including coefficient difference (C.D) test, Miff test, discriminant function analysis and hierachical cluster analysis combined with the ecological study, are employed to test and analyse the morphometric characteristics such as the second dorsal fin, the anal fin, the left and right pectoral fins, the ratios of body height to body length, head length to body length and head length to body height. The results indicate that the T. hypargyreus stock in the East China Sea is different from that in the south China Sea, named the Stock of the East China Sea and the stock of the South China Sea, respectively. Meanwhile, some management opinions are also put forward on the stock of the East China Sea.
