River Dolphin Conservation and Welfare

River dolphins are among the most endangered cetaceans in the world. Their welfare is threatened by fishing nets, pollution, boat strikes, and habitat degradation in some of the world's most densely populated river basins.

Key Facts

The Yangtze river dolphin (baiji) is almost certainly extinct — possibly the first cetacean driven extinct by human activity.
The Ganges river dolphin (susu), Indus dolphin, and Amazon river dolphin (boto) are all listed as endangered or vulnerable.
Entanglement in fishing nets (bycatch) is the leading cause of river dolphin mortality in most species and ranges.
River dolphins are functionally blind — they navigate entirely by echolocation in silty, turbid water.
The Amazon river dolphin has suffered population declines of up to 65% in parts of its range due to deliberate killing for use as catfish bait.

Welfare Considerations

River dolphins occupy a uniquely vulnerable position: they are highly intelligent cetaceans living in the world's most heavily human-modified river systems. Entanglement in fishing gear causes drowning — a prolonged, terrifying death for air-breathing mammals. Deliberate killing for bait demonstrates how little consideration these animals receive in communities under economic pressure. Their welfare and their survival are simultaneously at risk. Conservation that includes welfare-informed anti-bycatch measures — modified nets, acoustic deterrents, fishing exclusion zones — protects individual dolphins while addressing population decline.

What You Can Do

Support WWF and Whale and Dolphin Conservation programs focused on river dolphin species.
Advocate for fishing gear modifications that reduce bycatch in river dolphin habitats.
Raise awareness about river dolphin species that are less well-known than marine cetaceans.
Support ecotourism initiatives that give communities economic stakes in dolphin conservation.
