Beluga whales are among the most commonly kept cetaceans in marine parks, and the growing ocean sanctuary movement offers a welfare-positive alternative to continued captive display.
Captive belugas experience chronic sensory deprivation compared to their wild counterparts, who navigate complex three-dimensional ocean environments, produce rich repertoires of vocalizations, and maintain intricate social bonds. Tank reverberations from their own echolocation may cause chronic disorientation. Performance training and public interaction disrupt natural behavior patterns. The reduced lifespan of captive belugas compared to wild individuals suggests fundamental unmet welfare needs. Ocean sanctuaries provide dramatically improved conditions but still represent managed captivity rather than full wild living. For belugas already held in captivity, sanctuary transfer represents a significant welfare improvement over continued pool housing.
