Marine Wildlife: Bottlenose Dolphin Inshore UK Welfare

Inshore bottlenose dolphin populations around the UK coast face multiple welfare threats from boat disturbance, fishing interactions, and pollution.

Key Facts

The UK has several resident bottlenose dolphin populations including the Moray Firth and Cardigan Bay
These populations are small (typically 100-200 individuals) and genetically distinct
Boat disturbance alters dolphin behaviour, disrupting feeding and resting
Acoustic disturbance from motorboats masks dolphin communication signals
Dolphins that become fed or associated with fishing operations are at greater risk of boat strike and entanglement

Welfare Considerations

Small, resident bottlenose dolphin populations are particularly vulnerable to chronic welfare harm from boat disturbance because the same individuals are repeatedly affected. Feeding disruption from boat pressure reduces energy balance. Acoustic masking impairs the communication on which social welfare depends. Designated marine protected areas with strict vessel management provide the most effective welfare protection.

What You Can Do

Follow dolphin watching guidelines including approach distance and speed restrictions
Never feed or attempt to interact with wild dolphins
Support Cardigan Bay and Moray Firth Special Areas of Conservation management
Report dolphin disturbance from vessels to Natural Resources Wales or Scottish Natural Heritage
Choose responsible wildlife boat trip operators that follow codes of conduct
