2021年1月1日起，长江流域重点水域开始施行暂定为期十年的常年禁渔。1月30日，国务院新闻办举行 新闻发布会，介绍长江十年禁渔中期评估成果和5年来阶段性成效。 长江江豚较2022年增加177头 农业农村部副部长张治礼介绍，长江十年禁渔时间跨度长、覆盖范围广，全面启动实施5年来，农业农 村部会同相关部委成立长江水生生物保护暨长江禁捕工作协调机制，沿江15省份扎实推进，取得了阶段 性积极进展。 ——生物多样性恢复持续向好。2021至2025年，长江流域累计监测到鱼类351种，比禁渔前增加43种， 鱼类小型化趋势得到遏制，水生生物完整性指数显著提升。 "旗舰物种长江江豚是目前长江中唯一的淡水鲸豚类动物，其生存状况直接反映长江生态系统的健康状 况。"张治礼说。2025年专项调查显示，长江江豚已经恢复到1426头，比2022年调查时增加177头，成为 长江大保护的重要生态名片。 不仅长江江豚数量实现恢复性增长，其他重点保护物种资源状况也有所好转。禁渔后新监测到四川白甲 鱼、滇池金线鲃等国家二级重点保护物种。"时隔30多年在长江中游发现鳤的产卵场，时隔20多年在重 庆江段发现自然繁殖的圆口铜鱼鱼卵，在赤水河发现鳗鲡的自 ...

Group 1 - The core viewpoint of the articles highlights the significant progress made in the implementation of the ten-year fishing ban in the Yangtze River, with various measures being taken to protect aquatic biodiversity and support displaced fishermen [1][2]. Group 2 - By the end of Q3 2025, all 142,000 fishermen with labor capabilities and employment willingness have successfully transitioned to new jobs, and 220,000 fishermen have participated in pension insurance, with 60,000 receiving pensions [1]. - Joint law enforcement efforts have maintained overall stability in fishing ban management, with a total of 13,224 administrative cases related to fishing being handled, a decrease of 16.2% year-on-year, and 2,984 criminal cases being solved, down 37.3% [1]. - The number of illegal fishing criminal gangs dismantled reached 450, marking a 26.6% decrease, indicating a dual decline in general illegal activities and organized fishing crimes [1]. Group 3 - China is enhancing the protection of rare and endangered species, with specific rescue action plans for flagship species such as the Chinese sturgeon and Yangtze finless porpoise, and over 970,000 Chinese sturgeons have been released into the wild by 2025 [2]. - Monitoring shows that over 60% of released sturgeons have successfully entered the ocean, and natural breeding trials for the Yangtze sturgeon have been conducted, achieving successful spawning and hatching for the first time in 2025 [2]. - The ecological status of the Yangtze River and its lakes has improved, with the water quality levels rising by two grades in the Yangtze mainstream and Poyang Lake, and by three grades in Dongting Lake from the pre-ban "no fish" level [2].

Core Viewpoint - The report highlights the positive trend in the recovery of aquatic biological resources in the Yangtze River Basin, emphasizing the importance of the ten-year fishing ban initiated in 2020 for ecological restoration [3][15]. Group 1: Aquatic Biological Resources - The Ministry of Agriculture and Rural Affairs, along with other departments, released a report indicating an overall improvement in the integrity index of aquatic biological resources in the Yangtze River Basin [3]. - The report notes that the Yangtze River's ecological environment has significantly improved, with clearer waters and the reappearance of rare species [3][15]. - The ten-year fishing ban has led to a noticeable increase in fish populations and sizes, with average weights of certain species increasing by up to 265.17% [15][16]. Group 2: Historical Context and Conservation Efforts - The history of aquatic species in the Yangtze River is marked by significant losses, including the functional extinction of the Yangtze River dolphin and sturgeon due to environmental degradation [7][17]. - The report recounts the story of "Qiqi," the last captive Yangtze River dolphin, which provided valuable research data before its death in 2002 [5][6]. - The ten-year fishing ban was initiated in response to the drastic decline in aquatic species, with the aim of restoring their populations and habitats [8][17]. Group 3: Research and Monitoring - Research teams have been actively monitoring fish populations and habitats, with significant data collection efforts in the Yangtze River and its tributaries [11][12]. - Recent findings include the successful breeding of the Yangtze sturgeon, previously thought to be extinct in the wild, marking a significant breakthrough in conservation efforts [16]. - The report emphasizes the need for continued artificial interventions and habitat restoration to support the recovery of endangered species like the Chinese sturgeon [17].
