摘要
根据1994年6月至1996年5月东海北部25°30′～33°30′N，128°00′E以西海域的调查资料，阐明了头足类的种类组成．主要种类数量的季节变化和时空分布。结果显示，东海北部头足类资源群体结构已发生变化，原先的优势种类日本无针马贼资源已衰退，而剑尖枪乌贼，太平洋褶柔鱼、金乌贼等已成为新的捕捞对象。文章还介绍了主要种类的渔场渔期及可持续发展的管理对策。
The paper was based on the survey conducted in the north area of East China Sea, 25°30'-33°30'N and west of 128°00'E, during June 1994 to May 1996. It elucidated the species composition ofCephalopod, the seasonal variation of main species' quantity and their distribution. The results showedthat the structure of Cephalopod resource had changed and that the original dominant species like Sepiellajaponica had declined while such species as Loligo edulis, Todarodes pacglcus and Sepia esculenta hadbecome new fishing generation. In addition, the paper presented the fishing area and period and themanagement methods for sustainable development.
