Wild Baiji Dolphin: An Extinction Warning

The baiji dolphin was functionally declared extinct in 2006, offering stark lessons about preventing freshwater cetacean extinctions.

Key Facts

The baiji (Lipotes vexillifer) was declared functionally extinct after a 2006 survey found zero individuals
Its decline was caused by overfishing reducing prey, bycatch in fishing gear, boat strikes, and habitat degradation
The Yangtze River baiji's loss makes it the first cetacean driven to extinction by human activity in modern times
The Yangtze finless porpoise faces similar pressures with fewer than 1,000 individuals remaining
China's Yangtze fishing ban implemented in 2020 provides hope for finless porpoise recovery
International efforts to maintain a captive baiji population failed - captive individuals did not survive
The baiji's extinction became a catalyst for establishing the Yangtze River protection law

Welfare Considerations

The baiji's extinction pathway involved decades of worsening conditions for surviving animals - decreasing food from overfishing, increasing mortality from nets and propellers, and acoustic pollution from intense river traffic. Surviving individuals experienced chronic food insecurity, physical injury, and disorientation in a degraded acoustic environment. The loss of the baiji is both a conservation catastrophe and a welfare failure at scale that must inform protection of surviving freshwater cetaceans.
