Marine Mammal Capture and Tagging Welfare Protocols

Research capture and tagging of marine mammals provides critical conservation data but requires careful welfare management.

Key Facts

Satellite tags on whales, dolphins and seals have transformed understanding of migration and behaviour
Capture-related mortality is very low in properly managed operations but is a welfare risk
Anaesthesia for cetaceans is impractical - procedures are done with chemical immobilisation or physical restraint
Attachment method of satellite tags affects tag retention time and skin integrity
Post-capture monitoring protocols detect any adverse responses to tagging

Welfare Considerations

Research capture and tagging causes acute stress and potential physical injury. The welfare cost must be weighed against conservation benefit: data from tagged individuals has protected entire populations. Minimising capture duration, using non-invasive attachment methods and monitoring post-release behaviour are essential welfare safeguards.
