【摘要】 海水養(yǎng)殖提供了大量水產(chǎn)品,創(chuàng)造了良好的經(jīng)濟效益,也緩解了對天然漁業(yè)資源的捕撈壓力。中國的海洋魚、貝類產(chǎn)量在20世紀90年代后大幅度增長,海水養(yǎng)殖產(chǎn)業(yè)的發(fā)展取得令人矚目的成就,極大地提升了海洋漁業(yè)在國民經(jīng)濟中的地位。然而,海水養(yǎng)殖業(yè)發(fā)展過程中,漁業(yè)水域環(huán)境惡化、養(yǎng)殖自身污染加劇、養(yǎng)殖品種種質(zhì)退化等問題日益突出,水產(chǎn)養(yǎng)殖病害造成的經(jīng)濟損失越來越大。在此背景下,海水養(yǎng)殖環(huán)境的生態(tài)修復技術得以不斷發(fā)展,在改善水質(zhì),促進健康品種養(yǎng)殖方面展示了良好前景。分析研究海水養(yǎng)殖的現(xiàn)狀和存在問題,總結生態(tài)修復技術的研究進展,對挖掘海水養(yǎng)殖潛力,推動海水養(yǎng)殖可持續(xù)發(fā)展,發(fā)展?jié)O區(qū)經(jīng)濟,增加漁民收入等都具有重要現(xiàn)實意義。為此針對我國海水養(yǎng)殖環(huán)境質(zhì)量的現(xiàn)狀和問題,結合生態(tài)修復技術的進展,對海水健康養(yǎng)殖的發(fā)展構想及對策進行了探討。

【Abstract】 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.
