River dolphins including the Amazon pink dolphin and South Asian river dolphins face severe welfare threats from pollution, fishing entanglement, and deliberate killing.
River dolphin welfare harms are diverse and severe: deliberate killing for bait causes acute traumatic suffering; fishing net entanglement causes drowning; mercury contamination causes chronic neurological disease; dam-imposed fragmentation creates population isolation and prey depletion. The baiji's extinction serves as a stark warning about what river dolphin welfare crises lead to when intervention comes too late. Amazon river dolphin conservation requires addressing the deliberate killing for bait fishing, a practice driven by economic incentives that need alternative solutions.
