根据对历年来东海虾类资源调查和社会调查资料分析 ,提出实施拖虾作业休渔措施的必要性。分析认为 :虾类资源是多种类组成的捕捞对象 ,不同种类生态属性不同、分布海域不同、繁殖期和幼虾出现高峰期不同、渔场和渔期不同等 ,指出拖虾作业休渔期不宜搞一刀切 ,应实行分区管理。北部 (31°0 0′N以北 )以广温广盐种类为主 ,宜实行伏季休渔 ;而南部 (31°0 0′N以南 )以高温高盐种类为主 ,宜在 4～ 5月份休渔。为有利于管理 ,可把拖虾休渔管理权下放给各省 ,由各省根据本省的实际情况确定具体的休渔时间。
Based on the survey of shrimp resources in the East China Sea over the years and analysis of social survey data, the paper put forward the necessity of implementing the fishing and fishing measures of shrimp farming. The analysis shows that: shrimp resources are a variety of fishing objects, different types of different ecological attributes, different distribution of the sea, the breeding season and shrimp appear the peak of different fishing grounds and fishing period is different, , Should be implemented partition management. In the northern part (north of 31 ° 0’N), broad-leaved and wide-salty species are dominant, and the summer off-season fishing should be practiced. In the southern part (south of 31 ° 0’N), high-temperature and high-salinity species are dominant, May fishing closed. In order to be beneficial to management, the management of the closure of the shrimp fishery may be delegated to the provinces, and the provinces determine the specific time of the moratorium on the basis of the actual situation in the province.
