Hope Springs Anew: Yangtze Sturgeon Reproduces in Wild
15 Dec
Summary
- First natural Yangtze sturgeon reproduction in over two decades observed.
- Scientists recreated ideal spawning conditions in China's Chishui River.
- Over 200,000 fertilized eggs were found, indicating a strong breeding event.
In a remarkable conservation success, the critically endangered Yangtze sturgeon has achieved natural reproduction in the wild for the first time in over 20 years. Scientists meticulously recreated ideal spawning conditions in the Chishui River, leading to the observation of over 200,000 fertilized eggs. This monumental achievement, after years of dedicated research, signifies a crucial step in reviving the iconic species from the brink of extinction.
The Yangtze sturgeon, once a vital part of China's longest river ecosystem, faced severe decline due to pollution and overfishing, leading to its declaration extinct in the wild by 2022. A dedicated team from multiple institutions worked tirelessly, experimenting with water flow patterns and riverbed conditions to restore suitable habitats for spawning.
Their efforts culminated in the Chishui River project, where a tailored 8,000-square-meter spawning ground was established. The successful hatching of minute sturgeon larvae on April 16, 2025, proves the species' natural reproductive capability and lays a foundation for full restoration, offering hope for aquatic ecosystems.
