On September 17, 2026, nearly 100 Chinese and international guests attending the World Mayors Dialogue · Wuhan and the 2026 Wuhan International Friendship Cities Cooperation Conference visited the Guanqiao campus of the Institute of Hydrobiology (IHB), Chinese Academy of Sciences.

HAO Yujiang, director of the Yangtze Cetacean Breeding and Conservation Center, introduced the institute’s work on ex-situ conservation, captive breeding and population recovery of the Yangtze finless porpoise. He also highlighted recent research progress and the role of scientific research in protecting the species.

The guests observed the porpoises at close range and learned how generations of IHB researchers have developed techniques for captive breeding and population conservation as part of broader efforts to protect the Yangtze River. The visit offered an insight into China’s progress in Yangtze conservation through the example of this endangered freshwater mammal, often known as the “smiling angel.”

Wuhan Vice Mayor YAO Bin commended IHB’s achievements in Yangtze finless porpoise conservation and the protection of aquatic biodiversity. He noted that the porpoise has become an important symbol of Wuhan’s ecological progress and called on IHB to build on its scientific strengths, advance research on porpoise conservation, promote public understanding of ecology, and share China’s experience in Yangtze River protection with international audiences.

The delegation also visited the porpoise rearing pools, the Freshwater Cetacean Specimen Exhibition and the Goldfish Exhibition, where they learned about China’s efforts to conserve freshwater biodiversity, preserve aquatic genetic resources and develop new varieties of ornamental and other fish.

During the visit, an ecological dialogue titled “Building and Sharing Livable Spaces” was held at IHB’s Baiji Dolphinarium. Eight mayors from around the world exchanged views on their approaches to ecological conservation and sustainable urban development.
