Pollution and control measures of aquaculture environment.

The current status of aquaculture environment pollution in China was analysed. The pollution sources and their impact on aquaculture and the surrounding aquatic environment were stated. Aquaculture environmental pollution can be caused by exogenous contamination and self-pollution of the culture. The industrial pollution,the agricultural pollution and the domestic pollution were main sources of the extrogenous contaminations,while the sources of self-pollution involved all the inputs and byproducts in the whole breeding process,including the fertilizers,the feeds,the fish medicines,the excrement of the culture species and the sediment. The paper introduced the in-situ remediation and ex-situ remediation technology which were commonly used in aquaculture environmental pollution control. On the basis of the analysis above,the control measures on aquaculture environment pollution was proposed in line with the China's national conditions,to provide ideas for improving the aquatic products quality and for promoting the sustainable development of aquaculture.
