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。
According to the survey data of shrimp in the northern East China Sea (26 ° 00 ’~ 326 ° 00’N, shallow water depth of 100m) from 1986 to 1991, the relationship between the depth of habitat of different shrimp and the distribution of water system in the survey area was studied. The shrimp resources in the sea area are divided into three ecological groups: broad temperature and low salt, wide temperature and wide salt and high temperature and high salt, and clarify the distribution characteristics of various ecological groups and main species. The article also describes the development of the shrimp fishery in the East China Sea, and discusses the future development measures.
