Pinnipeds in zoos and aquariums have complex welfare needs requiring spacious pools, social management, and freedom from performance demands that stress these intelligent marine mammals.
Pinniped welfare in captivity has improved significantly as accredited zoos have moved away from entertainment-focused shows toward welfare-centered management. Traditional performances requiring repeated unnatural behaviors like ball-balancing and posing create chronic stress through aversive training methods and constant public demand for performance. Educational demonstrations that showcase natural behaviors and serve conservation messaging represent a welfare-positive alternative. Pool design must provide sufficient space for swimming, diving, and social interaction. Haul-out areas for rest and thermoregulation are essential as pinnipeds must be able to leave the water. Social group composition must be carefully managed as pinnipeds have complex dominance relationships.
