【摘要】 本文根据2002年4月-2003年1月对哑铃湾海域网箱养殖区的调查数据,分析该海域网箱养殖自身污染情况,同时结合哑铃湾的养殖现状和赤潮发生状况,初步探讨了该湾网箱养殖自身污染与赤潮发生的关系,结果表明,网箱养殖增加了水体中N、P的含量,使N、P结构特征发生改变,加速了哑铃湾养殖海域的有机污染和富营养化,为赤潮的发生提供了物质条件。春、秋季养殖海域已具有潜在富营养化,尤其是秋季,是大亚湾赤潮多发季节,应对该季度提高警惕。更多还原

【Abstract】 Based on the investigate data of cage culture from April, 2002 to January, 2003, in Yaling Bay. The self-pollution of cage culture was analyzed, and the relationship between red tides and self-pollution of cage culture was discussed, according as the actuality of culture and the states of red tide occurring in Yaling Bay. The conclusion indicated that the cage culture increased the content of nitrogen and phosphorus, changed the N-P ratio, and accelerated organic pollution and eutrophication of Yaling Bay. The culture area is already in the potentially eutrophic level in spring and autumn, but autumn that the season of red tide is often occurring will be especially regarded.更多还原
