摘要
据长江口、杭州湾渔业水域环境状况与我国水产养殖特点,分析研究了水产养殖和水环境的相互关系。目前两水域已受到无机氮、有机物、活性磷、石油类、重金属等不同程度的污染,并且这些物质的含量均已超过我国渔业水质标准或一类海水标准。而两水域具有重要的渔业经济价值,其沿岸地域是上海市等地区海产品养殖基地。两水域的污染状况,影响了该地区水产业的健康发展;目前水产养殖所采用的高密度、高投饵率、高换水率的传统养殖法也是造成水域环境污染的因素之一。为此提出应及早研究和制定长江口与杭州湾环境容量基准和上海沿岸地区养殖容量基准、尽快完善有关法律与法规制定、强化执法与管理、提高沿岸排放废水处理的强度、建立水资源收费和排废配额制度等建议。
The relation between the aquaculture in Shanghai area and water environment was studied according to the aquaculture character of China and the water environment conditions in the mouth of Yangtse River and Hangzhou Bay. At present the above waters were polluted in varying degrees by inorganic nitrogen, organic substances, activated phosphorus, petroleum and heavy metals. The contents of all these pollutants exceeded the standard of fisheries water quality or the first category of seawater quality standard of China. The above waters have important value of fisheries economy. The traditional culture method , in which high density and water exchange are used, is one of the main waterpolluting factors. Therefore it was proposed that the water environment capacity and culture capacity in mouth of Yangtse River and Hangzhou Bay should be studied and relative standards should be made. The treatment of drained waste should be strengthened, while emission control regulations and charging rules should be established.
