摘 要:长江流域拥有丰富的湿地资源,孕育了丰富的鱼类资源和发达的渔业。长江渔业在中国淡水渔业中占举足轻重的地位,在种质、苗种、名特优鱼类上具有资源优势。介绍了长江流域的湿地,渔业及天然渔业资源的概况,渔业的现状及存在的问题。近年来,由于渔业资源的衰退与长江湿地资源受到严重破坏,长江捕捞渔业严重衰退,而养殖渔业有较大的发展。长江在我国淡水渔业中的地位是基因库、原种基地和珍稀物种的乐园而不应是天然渔场,应大力发展养殖渔业,捕捞渔业应退出长江,为湿地的合理利用和保护发挥重要作用。There are abundant wet land resources in the Yangtze valley, which are pregnant with rich fish resources and developed fishery. The fishery of the Yangtze valley plays very important role in the Chinese freshwater fishery, with resources superiority in breed quality, fry kinds, famous and special fishes. This paper presents the general situation of wetland, fishery and natural fishery resources, the status-quo and existing problems of fishery. In recent years, due to declining of fishery resources and severe damage of wetland resources of the Yangtze valley, the catching fishery declines severely, but culture fishery develops considerably. The role of the Yangtze river is the gene base, original breed base in Chinese freshwater fishery and the paradise of valuable and rare fishes, but not a natural fishing field. The culture fishery should be developed greatly and catching fishery should be retreated in the Yangtze valley to give important contribution to the reasonable utilization and protection of wetland.
