Chinese Sturgeon
Acipenser sinensis
A 140-million-year-old giant that once swam 3,000 km up the Yangtze to spawn — dams cut the journey, and natural spawning has ceased.

- Habitat
- Yangtze River and adjacent seas; historically migrated 3,000 km upstream to spawn
The story
Chinese sturgeon outlived the dinosaurs but not the damming of the Yangtze. With no confirmed natural reproduction since 2017, the species hangs on through massive hatchery releases — over a million fry in some years — and the river-wide fishing ban, while scientists attempt to engineer new spawning grounds.
What's killing them
- Gezhouba and Three Gorges dams blocking spawning runs
- Vessel strikes
- Pollution
- Historic overfishing
