Core Viewpoint - The ten-year fishing ban on the Yangtze River has shown significant positive effects on the recovery of aquatic biodiversity and ecological health, while also facing ongoing challenges in conservation and management [12][13]. Group 1: Ecological Recovery - The Yangtze River's aquatic biodiversity has improved, with the number of indigenous fish species increasing from 308 to 344 since the ban was implemented [2][3]. - The population of the Yangtze River dolphin (Yangtze finless porpoise) has also seen a notable increase, with numbers rising from 1,012 in 2017 to 1,249 in 2022 [3][11]. - The overall water quality in the Yangtze River has improved, with transparency increasing and instances of algal blooms decreasing, leading to a stable water quality rating of Class II [5][9]. Group 2: Challenges and Future Directions - Despite the recovery of common fish species, rare and endemic species are still recovering slowly, indicating that the overall biodiversity restoration will require more time [4][11]. - Human activities, such as shipping noise and pollution from agriculture and industry, continue to pose significant threats to the ecological recovery of the Yangtze River [9][10]. - There is a need for a comprehensive assessment and monitoring system to better understand ecological changes and to develop more effective conservation strategies [4][10]. Group 3: Societal Impact and Awareness - The fishing ban has led to increased public awareness and engagement in ecological protection, with educational initiatives for children and community involvement in conservation efforts [7][8]. - The economic benefits from improved ecological conditions are evident, with increased tourism and local economic activity around conservation areas [7][8]. - However, there is still a lack of scientific understanding among the public regarding ecological protection, highlighting the need for better education on responsible practices [8]. Group 4: Policy and Strategic Initiatives - The ten-year fishing ban is part of a broader strategy to promote ecological civilization and sustainable development in the Yangtze River Economic Belt [12]. - Future efforts should focus on habitat restoration, protection of rare species, and the establishment of a comprehensive rescue system for endangered species [11][12]. - The experiences gained from the Yangtze River's fishing ban can serve as a model for ecological governance in other river basins [12][13].
