深水网箱养殖海域营养盐状况分析研究

Monitoring and Analysis of Nutritive Salts in Sea Area of Net-cage Culturing

2003～2004年间在秀山、朱家尖、册子3个不同地点的深水网箱养殖海区采集水样,根据海洋监测规范犤1犦对样品的营养盐进行监测分析,结果表明:网箱养殖海区的营养盐状况虽然比非养殖海区偏高,但是差别较小,说明养殖未给周围水环境带来严重污染。而根据水质质量标准,该养殖海区营养盐超标现象严重,属四类海水标准,且富营养化状况严重,但这在浙江沿岸尚属正常。

Monitoring and analyzing the nutritive salts of water samples collecred from the sea area of net-cage culturing in Xiushan,Zhujiajian and Cezi in different seasons from 2003 to 2004,according to the standard of the specification for marine monitoring,came to the conclusions that although the nutrients in this sea area of mariculture is higher than other sea area uncultivated,the difference is not vivid,which indicated that the culturing area hadn′t been heavily polluted .In accordance with the quality criteria of water,the eutrophiation was serious in this sea area,but it was very normal off Zhejiang.
