Group 1: Conservation Efforts - The Sichuan-Chongqing salmon has not been seen in its known distribution area since 1998, leading to a conservation initiative that has lasted nearly 30 years [4]. - The research team has developed full artificial breeding techniques for the salmon, achieving a significant breakthrough in 2024 [5]. - The successful breeding program has allowed for the reintroduction of 2,700 second-generation salmon into the wild, marking the largest release of this species to date [5]. Group 2: Ecological Impact - The reintroduction of the Sichuan-Chongqing salmon is part of a broader effort to restore the ecological balance in the Yangtze River, which has seen positive changes over the past five years due to a fishing ban [5]. - Monitoring efforts, including environmental DNA analysis, have confirmed the survival and adaptation of the released salmon in their natural habitat [5]. - The establishment of a provincial aquatic genetic resource protection area further supports the long-term conservation of the species [5].
