River Dolphin Conservation and Welfare

The critical welfare and conservation situation facing freshwater dolphins in Asia and South America.

Key Facts

River dolphins include the Amazon river dolphin, Ganges river dolphin, Irrawaddy dolphin, and Yangtze finless porpoise
The Baiji (Yangtze river dolphin) was declared functionally extinct in 2006 — the first cetacean driven to extinction in modern times
The Yangtze finless porpoise is critically endangered with approximately 1,000 individuals remaining
River dolphins face threats from entanglement in fishing gear, boat strikes, dam construction, and water pollution
Amazon river dolphins (pink dolphins) are killed for use as catfish bait in some fishing communities
Ganges river dolphins navigate by echolocation due to near-blindness in their turbid river habitat

Welfare Considerations

River dolphin welfare exists at the edge of extinction for several species, where the line between individual welfare and species survival has effectively merged. The welfare conditions facing surviving river dolphins are severe: entanglement in fishing gear causes drowning — an acutely distressing death for an air-breathing mammal — while pollution-degraded habitat creates chronic physiological stress and reduces prey availability. Dam construction fragments populations, trapping individuals in sections of river that may not support adequate food resources. The extinction of the Baiji represents the ultimate welfare and conservation failure: an entire evolutionary lineage eliminated within human lifetimes through preventable causes. Protecting remaining river dolphin populations requires addressing the fishing practices, dam policies, and pollution sources that have driven declines, creating welfare benefits for surviving individuals alongside conservation benefits for populations.

What You Can Do

Support organizations working on river dolphin conservation in Amazon, Ganges, and Yangtze river systems
