中文摘要：

营养盐的过度积聚是富营养化的主要表现,而以富营养化和底层生物沉积为主要特征的浅海网箱养殖自身污染是制约网箱养殖业健康发展的瓶颈之一.浅海网箱养殖中养殖生物、污损生物和野生鱼类等排泄,水-土界面营养盐的交换是养殖系统自身污染营养盐的主要来源.而开展鱼类环境动态负荷、污损生物及其他生物的资源量与生态效应,颗粒物/沉积物中营养盐再生等是进行自身污染营养盐来源研究的主要问题.

英文摘要：

It is self-pollution of net cage culture stamped by eutrophication and bio-sediment to limits the healthy development of this industry. The eutrophication is mainly represented by overage accumulation of nutrient salt. In shallow sea, the excretions of cultivated organisms, fouling organisms and wild fish, exchanges of nutrient at the interface between nutrient salt sources of self-pollution in culture net cage culture self-pollution in shallow sea,it of cultivated fish,the resources and ecological e water and sediment or particulate matters are the major system. Thus, in the research on nutrient salt sources of is important to study the environmental dynamic loadings ffects of fouling organisms and other kinds of organisms, and nutrient salt regeneration in particulate matters or sediment.
