摘要
虾类是东海区的主要捕捞对象之一。东海区的拖虾渔业以虾类为主要捕捞目标,发展之初对于促进捕捞结构调整、减轻主要经济鱼类的捕捞压力起了重要作用。但是随着该种作业方式生产规模的不断扩大、生产渔船和渔具的大型化,渔获物中经济虾类和兼捕幼虾的矛盾日益突出,对东海区的渔业资源造成较大程度的破环。本文主要介绍了东海区拖虾渔业的发展和资源概况,主要经济虾类的种类、分布、作业渔船的产量和数量变化,分析了东海区拖虾渔业中存在的问题和所采取的措施,并提出了解决问题的建议。
Shrimp is one of the main targeted fishing species in the East China Sea. The shrimp beam trawl is a fishing method widely used in the East China Sea for shrimp fishing. At the beginning,the shrimp beam trawl played a positive role in adjusting the fishery structure and reducing the fishing pressure on economic species. But as the fishing scale expanded and rapid development of fishing vessels and gears,the problem of major economic shrimp species and by-catch juveniles being caught became more serious,thus destroyed the fishery resources in the East China Sea. The paper mainly introduced the development of shrimp beam trawl in the East China Sea,and the species,distribution of major economic shrimp species,as well as the catches and number changes of fishing vessels in the area,analyzed the existing problems in the shrimp beam trawl fishery and put forward countermeasures.
