Core Viewpoint - The article discusses the successful second wild release of Yangtze River dolphins, highlighting the efforts made to enhance their survival skills and the importance of these actions for the ecosystem's health [1][5][7]. Group 1: Wild Release Actions - The second wild release of two Yangtze River dolphins took place on November 14, marking a significant step in conservation efforts [1]. - Prior to the release, extensive health checks and training were conducted, including identity scanning and physical examinations [3]. - The dolphins underwent over two years of training to adapt to the natural environment, focusing on survival skills such as adapting to water flow and noise [3][5]. Group 2: Training and Monitoring - The training for the dolphins included exposure to realistic environmental sounds to better prepare them for the challenges they would face in the wild [5]. - A wearable tracking system was developed to monitor the dolphins post-release, allowing for precise location tracking [13]. - The first group of released dolphins has successfully adapted to their environment, forming groups and finding food [13]. Group 3: Conservation Strategy - The wild release program is experimental, with no prior global examples to follow, necessitating a careful and gradual approach [7]. - A long-term plan has been established to develop a stable and sustainable population of Yangtze River dolphins by 2035 [11]. - The selection of dolphins for release is based on rigorous analysis, ensuring minimal impact on genetic diversity [11]. Group 4: Ecological Impact - The Yangtze River dolphin's survival is closely tied to the health of the river's ecosystem, which has improved due to ongoing conservation efforts and fishing bans [19][21]. - Continuous monitoring and enforcement against illegal fishing practices have contributed to the recovery of fish populations, which are vital for the dolphins' survival [19][21]. Group 5: Breeding and Research Advances - The Yangtze River dolphin breeding center has achieved significant milestones, including the establishment of a sperm bank and successful artificial breeding techniques [24][25]. - The research center aims to further enhance breeding technologies to ensure the long-term survival of the species [25]. - The overall conservation efforts reflect a collaborative approach among various stakeholders, showcasing the positive outcomes of sustained ecological protection initiatives [25].
