Pinnipeds in zoo and aquarium settings have specific welfare needs related to swimming space, social structure, and the management of trained behaviors.
Pinniped welfare in zoos and aquariums sits at the intersection of entertainment traditions and modern welfare science. Sea lion shows that involve repetitive performances, loud music, and close crowd proximity create stress that conflicts with welfare science. Training behaviors using positive reinforcement does provide cognitive enrichment, but the performance context may undermine this benefit. Swimming space requirements for animals that travel hundreds of miles in the wild cannot be fully met in zoo settings, but large, deep pools that allow diving and sustained swimming provide substantially better welfare than shallow display tanks. The welfare of performing pinnipeds has improved in facilities that have transitioned from performance shows to behavioral demonstrations with welfare education, reduced crowd intensity, and greater animal agency to participate or withdraw.
