Pinnipeds in marine entertainment facilities face welfare challenges from confinement and performance demands.
Seals and sea lions in marine parks are typically trained using operant conditioning with food rewards, but many facilities still use food restriction to increase motivation — a practice that creates chronic hunger stress. Captive environments provide a tiny fraction of the space wild pinnipeds use, and social groupings often fail to replicate natural colony structures. Public attitudes have shifted dramatically since the 1990s, with many parks retiring pinniped shows in favor of more educational formats.
