China Releases Fish in Five Major River Basins on World Environment Day
On June 5, 2026 — the 55th World Environment Day — China conducted synchronized fish stock enhancement and release operations across five major river basins, marking a significant demonstration of the country’s commitment to aquatic ecological restoration and biodiversity conservation.
According to CCTV News, the operations took place in the Jinsha River, Yalong River, Lancang River, and other major basins under the 2026 Chinese World Environment Day theme: “Comprehensive Green Transformation, Build a Beautiful China Together” (全面绿色转型，共建美丽中国).
Context: A Coordinated National Effort
The synchronized multi-basin action represents one of the most coordinated aquatic restoration efforts China has undertaken on World Environment Day. The Jinsha River is the upper section of the Yangtze River, China’s longest waterway; the Yalong River is a major tributary of the Jinsha; and the Lancang River becomes the Mekong River downstream, flowing through Myanmar, Laos, Thailand, Cambodia, and Vietnam — giving the initiative transboundary environmental significance.
The Chinese World Environment Day theme for 2026 was announced on February 27 by Ministry of Ecology and Environment spokesperson Pei Xiaofei. As Guangming Online reported, the theme aims to “fully implement the decisions of the Party Central Committee, firmly establish and practice the concept that lucid waters and lush mountains are invaluable assets, and take carbon peak and carbon neutrality as the driving force.”
The National Main Event
The national main event for World Environment Day 2026 was jointly hosted in Guangzhou by the Ministry of Ecology and Environment, the Central Civilization Office, and the governments of Guangdong, Hong Kong, and Macao — marking the first time the three regions jointly hosted the national celebration. During the event, the Ministry released the “2025 China Ecological and Environmental Status Bulletin,” which for the first time included participation from Hong Kong and Macao environmental departments in its compilation.
Fish Stock Enhancement: A Key Restoration Tool
China’s fish stock enhancement program (增殖放流) is a long-standing component of its aquatic ecological restoration strategy, particularly aimed at mitigating the ecological impacts of hydropower dam construction. Major hydropower companies operate fish breeding and release stations along key rivers. For example, Huaneng Lancang River Company has conducted 162 release events, releasing over 13.18 million rare fish fry into the Lancang River, and has mastered breeding techniques for 15 native fish species. The Wujiang Company has been conducting fish releases for 16 consecutive years since 2009, releasing a cumulative 12.127 million fry into the Wujiang River basin.
Analysis: Balancing Hydropower and Ecology
The synchronized fish release highlights China’s ongoing effort to balance extensive hydropower development with biodiversity conservation. The country’s major rivers — particularly the Jinsha, Yalong, and Lancang — host some of the world’s largest hydropower projects, which disrupt fish migration routes and breeding grounds. Stock enhancement programs are a key mitigation measure, though questions remain about their long-term effectiveness compared to preserving natural river habitats.
The international dimension is particularly significant for the Lancang River. As the upstream of the Mekong — a river that supports one of the world’s most productive inland fisheries and provides food security for millions in Southeast Asia — China’s management of aquatic ecosystems has direct transboundary implications.
Broader Environmental Context
The fish release operations were part of a wider series of activities across China during “Beautiful China Publicity Week” (June 1–7). Multiple provinces held their own World Environment Day events, including Hangzhou, Shanxi, Shandong, Zhejiang, Inner Mongolia, and Jiangsu. The week-long campaign aims to mobilize全社会 (all of society) to adopt green production and lifestyles, supporting China’s “Beautiful China” initiative and its carbon peak and carbon neutrality goals.
What to Watch For
As China continues to implement its “Comprehensive Green Transformation” strategy, several questions remain: Which two river basins complete the “five major river basins” beyond those named? What specific fish species were released, and how many? And how does this year’s synchronized release compare in scale to previous years? The answers will help gauge the true scope of China’s aquatic restoration ambitions and their effectiveness in preserving biodiversity for future generations.
