Core Viewpoint - The population of the Yangtze finless porpoise, a critically endangered freshwater species, has increased to 1,426 individuals, indicating improvements in the ecological health of the Yangtze River [3][5]. Group 1: Population Recovery - The Yangtze finless porpoise population has increased by 177 individuals compared to the 2022 survey [3]. - The species is considered a flagship species for the Yangtze River ecosystem, serving as an indicator of the river's health [5]. Group 2: Conservation Efforts - Following a complete fishing ban in Poyang Lake, local fishermen have been recruited as patrol members to protect the porpoises, transforming from fishers to guardians [3]. - The patrol teams are crucial during the dry season when water levels drop, limiting the porpoises' activity range [3]. Group 3: Ecological Significance - The increase in the finless porpoise population reflects better water quality and greater biodiversity in the Yangtze River [5]. - The species' habitat requirements highlight the importance of maintaining a healthy ecosystem in the Yangtze River [5].
