Wild Bottlenose Dolphin Population Welfare

Wild bottlenose dolphin populations face multiple stressors affecting individual welfare and population health.

Key Facts

Bottlenose dolphins show complex social bonds with lifelong relationships between individuals
Exposure to pollutants including PCBs and mercury causes immune suppression and reproductive failure
Bycatch in fishing gear kills thousands of bottlenose dolphins annually in European waters
Boat disturbance disrupts foraging, resting, and social behaviour in key habitats

Welfare Considerations

Individual bottlenose dolphins experiencing pollution, bycatch, and disturbance suffer acute and chronic welfare compromise. Social bonds between individuals mean that loss of companions through bycatch or pollution affects surviving pod members. Population-level welfare decline requires systemic solutions.

What You Can Do

Support Whale and Dolphin Conservation cetacean protection campaigns
Choose seafood from fisheries with bycatch reduction measures
Advocate for pollution controls protecting marine mammal health
