Water Quality for Mariculture and Its Ecological Rehabilitation Technology

China has a long history in aquaculture.Mariculture provides not only nutritional and economic benefits,but also decrease intensity of exploitation on declining wild living resources.Production of marine fish and mollusc has been increasing sharply since 1990's.As mariculture plays an important role in national economy,the rapid development and changes in mariculture species have aroused increasing concern about mariculture's impact on coastal environment.The impact of coastal aquaculture,may include water quality deterioration and contaminants,self-pollution of mariculture,decrease of culture species' which results in a significant bearing on the expansion of mariculture.Under the condition mentioned above,ecological rehabilitation technologies on mariculture also have made great progress and have promising future in improving water quality and advancing healthy aquaculture.So,it is imperative to study the status of mariculture and the development of ecological rehabilitation technologies,which are indispensable to develop sustainable aquaculture.The article studies the status of mariculture,combining the advances in ecological rehabilitation technology,and then discusses the developing prospects and countermeasures of how to make mariculture develop in a sustainable approach.
