受非法渔具的威胁,长江鱼类资源趋于衰竭的情形近年来频频见诸报端。三峡水库形成后,非法渔业“酷捕滥捞”的形势同样严峻,对水库鱼类资源和生态系统造成了较大的压力。三峡水库蓄水后,许多农民转行成为渔民,渔船数量大幅增加,捕捞强度持续增强,对鱼类资源的可持续发展产生了重大影响。对水库不同水域渔具渔法的调研,将从管理角度指导生态渔业管理规划编制,确保生态渔业的实施效果,同时造福于当地百姓。 Under the threat of illegal fishing gear, the Yangtze River fish resources tend to decline frequently reported in recent years. After the Three Gorges Reservoir was formed, the situation of illegal fisheries and “cool catch fishing” was equally severe, putting a lot of pressure on reservoir fish resources and ecosystems. After the impoundment of the Three Gorges Reservoir, many peasants switched to become fishermen. The number of fishing vessels increased sharply and their fishing intensity continued to increase, which had a significant impact on the sustainable development of fish resources. Investigation and research on fishery fishing methods in different waters of the reservoir will guide the preparation of ecological fishery management planning from the perspective of management so as to ensure the implementation effect of ecological fisheries and benefit the local people at the same time.
