新华社昆明8月20日电（记者林碧锋）记者20日从云南省水富市农业农村局渔业站获悉，摄影爱好者近日在长江上游金沙江水富段，拍摄到国家一级重点保护野生动物长江鲟的身影，表明当地生态环境持续改善。
“我们通过摄影爱好者拍摄的视频判定这是一条长江鲟。视频显示，长江鲟与其他鱼类和谐共处，尽显生态之美。”水富市农业农村局渔业站站长罗兴国介绍，长江鲟作为地球上最古老的脊椎动物之一，是国家一级重点保护野生动物，主要分布于长江中、上游的干支流，素有“水中大熊猫”之称，具有极高的科研价值和生态价值，是长江流域独有的珍稀鱼类。
近年来，水富市积极开展长江十年禁渔专项整治行动，实施网格化管理，持续加大执法检查力度，依托水富市长江流域重点水域禁捕智能监管平台，对重点水域实现全面监控，推动生态环境持续向好。
“近年来，科研机构在水富市还监测到岩原鲤、胭脂鱼等珍稀鱼类。”罗兴国说，2023年以来，水富市累计监测到长薄鳅、大眼鳜等鱼类60多种，表明长江上游珍稀特有鱼类国家级自然保护区（云南水富段）的珍稀特有鱼类多样性持续增强。
KUNMING, Aug. 20 (Xinhua) -- The Yangtze sturgeon, an endangered species under first-class national protection, has been spotted in the upper stream of the Yangtze River in southwest China's Yunnan Province, the local agricultural authority said Tuesday.
Images of the rare fish were captured recently by photography enthusiasts on the river.
"The video shows that the Yangtze sturgeon coexists in harmony with other fish, highlighting the positive impact of a comprehensive fishing ban in the area," said Luo Xingguo, head of the fishing station under the city of Shuifu's agriculture and rural affairs bureau.
The city has monitored 62 fish species since 2023, including some rare ones, demonstrating that the diversity of rare and endemic fish continues to increase in the region, Luo added.
The Yangtze sturgeon, also known as the Dabry's sturgeon, is one of the oldest vertebrates on Earth. Enditem
