摘要:
渔业是太湖的主要功能之一,它对改善水环境具有重要意义,但又受制于环境的影响而变化.从太湖渔业结构分析.目前太湖自然渔业整体捕捞强度过大、资源破坏严重.依据太湖多年渔获物捕捞结果,系统分析了太湖鱼类群落结构及其演变动态.通过对太湖不同生态区域渔获物产量和组成的分析,研究了太湖自然渔业特征及存在问题,提出了严格控制捕捞渔具规格和捕捞强度、合理调整开捕时间、调整放流鱼种结构和比例,合理发展湖泊渔业的思路.同时,依据太湖生物资源现状.分析了太湖自然渔业潜力,提出太湖渔业发展要加强渔业环境建设、加强渔业对水环境改善功能的研究.

Abstract:
Fishery is one of the main functions of Lake Taihu, which plays an important role in improving the water environment. However, it is also influenced to a large degree by the environmenal change. Recently, the main problems facing the natural fishery in Lake Taihu are the over-intensive catching and irrational utilization of natural resources. This paper, based on the data of many years'catches in Lake Taihu, analyzed the community structure of fishes in Lake Taihu and their succession dynamics. According to the fish yields and compositions in different area of Lake Taihu, the natural fishery characteristics and problems were studied. Some ideas were presented to develop the natural fishery based on the present research, such as controlling the fishing gear specifications and catching intensity, adjusting the catching time, regulating the structure and proportion of stocking fish species and developing lake fishery in a reasonable way. Meanwhile, the potential of natural fishery was analyzed on the basis of present biological resources in Lake Taihu. It suggested that the construction of fishery environment and studies on influence of fishery on water environment should be strengthened for the further development of lake fishery.
Key words:  Lake Taihu  natural fishery  catches  community structure
