【摘要】 本文根据1986～1991年对东海北部海域（26°00’～326°00’N，100m水深以浅）虾是调查资料，研究了不同虾类的栖息水深与调查区水系分布之间的关系，把本海区的虾类资源划分为广温低盐，广温广盐和高温高盐三个生态类群，并阐明各生态类群及主要种类的分布特点。文中还叙述了东海区拖虾渔业的发展现状，讨论了今后的发展对策。更多还原

【Abstract】 On the basis of investigation data from the shrimp trawling in the north waters of theEast China Sea (26°00’ ~ 32°00’N, west to 100m isobath) from 1986 to 1991, the authorsstudies the relationship between inhabiting depths of djfferent shrimps and distribution ofwater systems in the investigation area. this paper classifies the shrimps into three ecologicalgroups-ueurythermal hyposaline group, eurythermal eurysaline group and hyperthermal-hypersaline group, and expounds the distribution characteristics of the ecological groups andthe maJor species. Finally, the aritle states the general developmental situation ofshrimptrawling fishery in the East China Sea and discusses the future development policy.更多还原
