中国发展网讯 "我的梦想就是，未来5-10年，研究所将抓住长江十年禁渔的契机，联合其它科研所，共 同实现长江上游旗舰物种长江鲟的野外种群重建和自然资源量恢复"。说出这个梦想的是四川宜宾珍稀 水生动物研究所所长周亮。 说起周亮，这个有着"鱼痴"称号的男子，在长江之滨的四川宜宾市，用30年的热爱与坚守只为守住他眼 中的"鱼"——长江鲟。 长江鲟又名达氏鲟、俗称沙腊子，是长江独有的珍稀野生动物，是长江上游水系的旗舰物种之一，也是 国家一级保护动物，被称为"水中大熊猫"。这样的珍稀鱼种与周亮又有哪些故事？他为何能30年如一日 的坚守？ 热爱，在青春中接力 长江边长大的周亮，对长江有着不同的情感。他对记者说，每次看见长江都有敬畏之情，就想着为这 条"母亲河"做些什么？ 1993年，刚从四川大学毕业的周亮，做出了一个让所有人错愕的决定——放弃城市繁华，追随父亲周世 武的脚步，扎进宜宾市长宁县的深山里，用日复一日的坚守，为长江生态留住珍贵的生命火种。 那里，有父亲周世武创办的中国最早的民营长江珍稀鱼类研究机构。至此，周亮便跟随父亲开启了人工 养殖中华鲟、长江鲟，胭脂鱼等珍稀鱼试验，踏上了长江上游珍稀特有鱼类的人工繁育探索之 ...

Core Insights - The overall recovery of aquatic biological resources in the Yangtze River Basin is positive, with a continuous improvement in integrity index and a need for enhanced protection of rare and endangered species [2][7] Group 1: Aquatic Biological Resources Recovery - In 2024, the unit resource amount in the main stream of the Yangtze River is 2.3 kg, an increase of 9.5% compared to 2023 [2] - From 2021 to 2024, a total of 344 indigenous fish species have been monitored, an increase of 36 species compared to the pre-fishing ban period (2017-2020) [2] - The overall water quality evaluation in the Yangtze River is rated as excellent, with 98.6% of monitoring sections classified as grade I-III, up 0.1 percentage points from 2023 [2] Group 2: Key Protected Species - The distribution range of the Yangtze River dolphin is expanding, and the number of certain key protected species is increasing, including the first natural reproduction of the lipstick loach in 30 years [3] - The resource amount of the four major economic fish species in the middle reaches of the Yangtze River is 6.2 times that of 2020 [3] - The implementation of a comprehensive fishing ban since 2017 has led to a steady increase in biodiversity in the upper reaches of the Yangtze River [3] Group 3: Conservation Efforts - The Ministry of Agriculture and Rural Affairs has guided the establishment of indigenous fish breeding farms in Guizhou, Sichuan, and Yunnan, releasing 6.63 million rare indigenous fish into the wild during the 14th Five-Year Plan period [4] - Successful monitoring of artificial breeding and spawning behavior of the Yangtze sturgeon has been achieved through habitat restoration efforts [4] - Restoration projects have improved the natural connectivity of tributaries, allowing rare fish species to re-enter and thrive in these areas [4] Group 4: Challenges in Biodiversity Recovery - Despite reports of increased fish populations in certain areas, the overall recovery of fish resources and biodiversity in the Yangtze River is still slow [5] - The slow recovery of flagship species such as the Chinese sturgeon and Yangtze sturgeon indicates ongoing survival crises for these species [7] - Historical data shows that 99 out of 443 fish species previously distributed in the Yangtze River have not been monitored since the fishing ban [5] Group 5: Future Conservation Strategies - There is a need to optimize and upgrade the rescue action plan for rare and endangered species, including expanding artificial breeding and release efforts for the Chinese sturgeon [8] - Continuous monitoring and removal of potential threats such as underwater nets and fishing lines are essential for species protection [8] - Further efforts are required to restore spawning grounds and promote natural reproduction of the Yangtze sturgeon to enhance self-sustaining populations [8]
