California sea lions are frequently injured by fishing gear, domoic acid toxicity, and malnutrition, with rehabilitation programs playing an important role in individual welfare.
Sea lion rehabilitation addresses acute welfare crises for individual animals suffering from human-caused and environmental harms. Animals that arrive at rehabilitation centers have experienced significant suffering — starvation, neurological damage, or traumatic injuries — and the welfare benefit of successful treatment and release is substantial. The rehabilitation process itself requires welfare-sensitive handling of highly stressed animals. Release programs include monitoring to assess outcomes and improve treatment protocols.
