Harbor seals are common zoo and aquarium species with complex enrichment and welfare needs. Managing human interaction and providing adequate aquatic space are key welfare priorities.
Harbor seal welfare in zoo and aquarium settings requires balancing public engagement with the animals behavioral needs and stress tolerance. Excessive proximity to the public, particularly in petting pool formats, causes chronic stress and habituates animals to inappropriate human contact. Pool design must provide sufficient depth and surface area for natural swimming behavior, including diving and underwater maneuvering. Land hauling areas with appropriate substrate allow normal resting behavior. Feeding training through operant conditioning serves both enrichment and welfare monitoring functions — animals that are trained to participate voluntarily in health checks experience less stress during veterinary procedures. Fish presentation that simulates natural prey capture engages hunting behavior and provides mental stimulation that prevents stereotypy development.
