摘要：桁杆拖虾是20世纪80年代以后迅速发展起来的新兴捕捞作业方式，主要用于开发沿海渔场虾类资源。桁杆拖虾作业方式引进舟山后，迅速成为舟山海洋捕捞业的主要作业方式之一。2013年5—11月通过实地调查，对舟山地区桁杆拖网的捕捞对象、渔具结构、操作方法等进行了分析研究，指出当前舟山桁杆拖虾作业中存在的问题：底杂鱼及蟹类等副渔获物所占比例大，数量和重量占总渔获12.12%和66.58%；使用电脉冲惊虾仪等违法作业仍然存在；网目规格普遍小于国家标准。根据上述问题提出：加装分隔网片，改善网目结构，加大执法力度等相应建议。

Abstract: The beam trawl fishing practices developed rapidly since the 1980s, mainly used for the development of coastal fishing ground’s shrimp resources. After brought in Zhoushan, the beam trawl fishery has rapidly become one of the main modes of fishery production. Through the field investigation during May-November 2013, the author investigated the fishing targets, structural features, operation-ways, etc. This paper points out the current problems in the beam trawl fishery :(1) The quantity and weight of by-product is 12.12% and 66.58% in total, respectively; (2) Illegal pulse-fishing operation still exist; (3)Mesh specifications generally less than the national standard. So on basis of those problems, some suggestion are raised：(1) Install the separator panel devices; (2) Improve the mesh configurations; (3) Intensify the law enforcements.
