据对沿母40多处重点渔港的调查和环保、水产科研部门检测,渔港水域含油、COD等主要指标都大大超过国家海水水质三类标准。据山东省不完全统计,每年因污染造成水产养殖的经济损失达一万元以上。另据浙江省有关部门介绍,在东经123°以西我国沿海水域都不同程度地受到污染。目前全国几大渔场都很难形成渔汛,唯一能形成渔汛的舟山渔场也是每况愈下,这些也与水质污染有关。
According to the investigation and environmental protection of 40 key fishing ports along the mother, the testing of scientific research departments of aquatic products, the oil content of fishing port waters, and COD all greatly surpass the three standards of national seawater quality. According to incomplete statistics in Shandong Province, the economic loss of aquaculture caused by pollution reaches more than 10,000 yuan every year. According to the introduction of relevant departments of Zhejiang Province, coastal areas in China are contaminated to varying degrees along the west of 123 ° longitude. At present, it is hard to form a fishing season for several major fishing grounds in the country. The only fishing ground for Zhoushan that can form a fishing season is also deteriorating. These are also related to water pollution.
