舟山渔场捕捞量约占我国海洋总捕捞量的1/4,对全国海洋渔业兴衰举足轻重。自70年代以来,主要的传统渔业资源逐步衰退,究其主因,除遭受捕捞力量发展过度、作业结构不尽合理的影响外,也与渔场西侧污染严重、水质恶化密切有关。据舟山市环保部门提供的数据,早在1985年,仅工业和生活废水排放在舟山渔场海域已达32.67亿吨,占我国沿海地区污水总排放量的52%。舟山渔场污染已对浙江省海洋渔业资源造成
Zhoushan fishery catches account for about one-fourth of China’s total ocean catches, the rise and fall of the national maritime fishery is decisive. Since the 1970s, the major traditional fishery resources have been gradually declining. In addition to the excessive development of fishing power and the unreasonable operating structure, the main causes of fishery pollution are also closely related to the serious pollution and the deteriorating water quality on the west side of the fishery. According to the data provided by the environmental protection department of Zhoushan City, as early as 1985, only the discharge of industrial and domestic wastewater in the waters of Zhoushan Fishing Ground reached 3.267 billion tons, accounting for 52% of the total discharge of sewage in China’s coastal areas. Zhoushan fisheries pollution has caused marine fisheries resources in Zhejiang Province
