Marine Mammal Rehabilitation and Release Standards

Marine mammal rehabilitation returns stranded and injured animals to the wild, but success depends on health, behavioral capacity, and release conditions. High standards are essential for welfare and conservation outcomes.

Key Facts

Hundreds of thousands of marine mammals strand globally each year, many requiring rehabilitation
Survival rates after rehabilitation vary from under 50% for some species to over 80% for others
Rehabilitation too long can result in animals that cannot survive independently after release
Release into appropriate habitat with conspecifics is critical for social species
Satellite tagging of released animals provides welfare data and validates rehabilitation protocols

Welfare Considerations

Marine mammal rehabilitation provides genuine welfare benefit to stranded animals, but success requires both medical care and behavioral preparation for release. Animals rehabilitated too long may lose foraging skills or become overly habituated to humans. Release timing, location, and conditions profoundly affect post-release survival. The best rehabilitation programs monitor released animals through tagging, use outcomes data to improve protocols, and make hard decisions about which animals can genuinely be released to a good quality of wild life.

What You Can Do
