Core Viewpoint - The implementation of the "Ten-Year Fishing Ban" in the Yangtze River has shown significant progress in restoring aquatic biological resources, particularly in the middle and lower reaches, while the upper reaches, especially the Jinsha River, face critical ecological challenges due to intensive hydropower development and climate change [1] Group 1: Ecological Restoration Efforts - The ecological restoration in the middle and lower reaches of the Yangtze River has been successful, with rare fish populations recovering rapidly due to good hydrological connectivity and intact habitats [1] - The Jinsha River, as a key ecological barrier, suffers from habitat fragmentation and disrupted hydrological rhythms, leading to the endangerment of unique fish species like the round-mouthed copper fish [1][2] Group 2: Proposed Solutions - A comprehensive protection mechanism for the Jinsha River basin is needed, integrating functions from various departments to manage ecological flow and enforce fishing bans effectively [1][2] - Habitat rescue projects are proposed to rebuild critical ecological corridors and enhance habitat diversity through artificial fish nests and spawning grounds [2] - The establishment of a genetic management system for endangered species is essential, focusing on the scientific release of local species and avoiding the introduction of non-native species [2][3] Group 3: Innovative Protection Models - The introduction of a three-pronged protection model focusing on genetics, populations, and habitats is recommended, including the establishment of a gene bank for endangered species [3] - Continuous monitoring of water quality and biodiversity is crucial to assess the impacts of hydropower development and ecological protection efforts [3]
