Abstract: 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 water and sediment or particulate matters are the major nutrient salt sources of self-pollution in culture system.Thus,in the research on nutrient salt sources of net cage culture self-pollution in shallow sea,it is important to study the environmental dynamic loadings of cultivated fish,the resources and ecological effects of fouling organisms and other kinds of organisms,and nutrient salt regeneration in particulate matters or sediment.

Key words: net cage culture, self-pollution, nutrient salt source
