Captive pinnipeds have been central to zoo entertainment for decades, but shifting understanding of their welfare needs is changing how accredited facilities manage these highly intelligent marine mammals.
Captive pinniped welfare depends significantly on pool environment and training approach. Early zoo pinnipeds were trained through food deprivation - a welfare-compromising method that is now largely replaced by positive reinforcement. Modern facilities with large, deep pools with varied complexity, appropriate group sizes, and enrichment programs provide substantially better welfare than older entertainment-focused facilities. The transition from performance to education has also improved welfare by removing the stress of performance cues and audience noise. Pinnipeds with behavioral training for voluntary health checks have dramatically reduced stress during veterinary care.
