摘要: |
东太湖是长江中下游典型草型湖泊,渔业资源丰富,水质良好,具有渔业、泄洪、供水等重要功能,作为我国最早开始网围养殖等养殖渔业开发的湖泊之一,在促进我国湖泊渔业的发展等方面起到了重要作用,但是养殖渔业的快速发展也带来了一定的负面影响,影响了湖泊渔业等的持续发展.本文以东太湖作为我国浅水湖泊的典型代表,在分析其主要资源及环境特征的基础上,重点分析网围养殖与环境之间的关系,剖析养殖渔业存在的主要问题,提出了相应的湖泊渔业养殖承载力资源环境模型,并就未来湖泊渔业发展提出建议. |

Abstract: |
Pen culture in lakes has been developed greatly especially in the past ten year's and has become a main part of the inland freshwater fisheries in China. East Taihu Lake is a typical one involving the development of fish pen farming in the past 20 years. Here the impacts of pen farming on lake ecological environment are analyzed and discussed from aspects of local and whole lakes.The resultshows that the ecological environment to has deteriorated a certain degree and has affected the functioning of water supply flood storage,flood discharge etc. As a feedback, the deterioration of lake environment has also strongly affected the pen farming and other fishery activities and caused the decrease of economic benefits. So it is very important to find a scientific strategy to keep a sustainable development of pen-culture of fishes. In this paper a conceptual model of capacity of pen culture of fishes in shallow lakes is promoted and discussed based on a case study on East Taihu Lake. Finally,the regulation and planning of fishery, especially the pen-culture in East Taihu Lake are presented which would be helpful to the management of the lake. |
