浙江海域频繁捕获野生大黄鱼的成因分析及其资源保护建议

Reason analysis and resource protection suggestions on the frequent catch of wild large yellow croaker in Zhejiang Province sea area

大黄鱼是浙江海域重要的海产经济鱼类,但由于过度捕捞和栖息地遭到破坏,从20世纪末开始,野生大黄鱼数量急剧下降,甚至一度被世界自然保护联盟(IUCN)列为极危物种。近期该区域捕获野生大黄鱼的新闻频繁出现,种群数量似有回归迹象。论文通过走访调查浙江象山石浦渔港、舟山沈家门渔港和六横岛台门渔港,了解捕获野生大黄鱼的相关情况,查看人工鱼礁投放模块;并在此基础上,运用文献比对、数据整理等方法,分析了近期野生大黄鱼捕获量增加的主要原因,并就该物种的保护与重建提出建议,供自然资源、生态环境、渔业养殖和捕捞等部门参考。

As a scarce fishery resource in the sea beside Zhejiang Province, the population of wild large yellow croaker(Larimichthy scrocea) is an important reference data for the ecological and environmental quality of the sea area. For a long period of time, large yellow croaker used to be an important marine economic fish in the East China Sea. However, due to overfishing and habitat destruction, the number of wild large yellow croaker has declined sharply since the end of the last century, and it was even listed as a critically endangered species by IUCN. Recently, news of wild large yellow croaker caught in this area has appeared frequently, and the population seems to be returning, which also brings dawn to the ecological restoration of wild large yellow croaker in the East China Sea. By visiting and investigating Shipu Fishing Port in Xiangshan, Zhejiang Province,Shenjiamen Fishing Port in Zhoushan and Taimen Fishing Port in Liuheng Island, this paper learns about the capture of wild large yellow croaker, and observes the artificial reef stocking module. On this basis, using methods such as literature comparison and data sorting, this paper analyzes the main reasons for the recent increase in the catch of wild yellow croaker, and puts forward various suggestions for the protection and reconstruction of species, which can be used as a reference for the departments of natural resources, ecological environment, fishery breeding and fishing.
