Sea Lion Rehabilitation and Release

California sea lions frequently strand due to domoic acid toxicity, entanglement, and malnutrition, requiring intensive rehabilitation care.

Key Facts

The Marine Mammal Center treats over 1,000 sea lions annually
Domoic acid from harmful algal blooms causes seizures and brain damage
Entanglement in fishing gear causes drowning and painful laceration injuries
Successful rehabilitation and release rates average 70-75% for sea lions
Some animals are treated multiple times over their lifespans

Welfare Considerations

Stranded sea lions often present with multiple injuries and severe malnutrition. Rehabilitation involves intensive veterinary care, force-feeding, and extended observation before release. Some sea lions with permanent brain damage require long-term facility care. Climate change is increasing domoic acid bloom frequency, worsening sea lion welfare outcomes.
