【摘要】 1972年杨鸿嘉根据对下颌齿和关节骨的研究,将东、黄海的带度(Trichiurus leptu-rus)分为“枪型齿带鱼”(T.lepturus auriga)和“钩型齿带鱼”(T.lepturus lepturus)。1977年李信徹等人又把带鱼分为“瘦带鱼”(T.japonicus)和“肥带鱼”(T.lepturus)两种。为弄清东、黄海带鱼的分种问题,本文作者自1982年春至1984年夏,于28～33°N,123～126°E海区采集完好的带鱼标本586尾,重复了二人的工作,对鱼体量度进行了协方差分析,并对下颌齿型、关节骨、鳃耙等作了综合研究。研究的结果表明:东、黄海带鱼只有一个种,即T.lepturusLinnaeus 1768;杨、李二人所定的两个种,或两个亚种(型),就是同一个种。更多还原

【Abstract】 In 1972, Hung-chia Yang in Taiwan studied the tooth form of the lowerjaw and the articular bones of largehead haitail. He derived the largehead hairtail in theDong Hai Sea into two subspecies. The point-toothed fish were designated Trichiuruslepturus auriga and the barb-toothed fish Trichiurus lepturus lepturus. In 1977,Mr. Sin-che Lee also classified the largehead hailtail into two species further. Onewas thin ribbon fish (T. japonicus with pointed teeth), the other was fat ribbon fish(T. lepturus with barbed teeth). To make clear the question,we collected 586 specimensfrom the Dong Hai Sea and Huang Hai Sea(28-33°N, 123-126°E) during the periodof spring in 1982 to summer in 1984,and repeated Yang and Lee’s Work. Some cova-riance analyses for the body admeasurement,the tooth form of lower jew,the shape ofarticular bone and the number of gillrakes of the fish have been studied synthetically.The results show that there is only one species of largehead hairtail Trichiurus leptu- rus Linnaeus (1758) in the Dong Hai Sea and Huang Hai Sea. Yang and Lee classifi-cation are invalid.更多还原
