Bottlenose dolphins in marine parks face welfare challenges from confined space, performance demands, and the social disruption of captive management.
The welfare debate around captive dolphins is among the most publicly prominent in zoo animal welfare. The constraints of even the largest marine park tanks prevent the essential behavioral repertoire of dolphins — long-distance swimming, deep diving, complex social choice, and active prey pursuit. Echolocation in tanks reflects off walls causing sensory distortion. Performance of tricks for food represents behavioral restriction rather than enrichment. The welfare case against captive dolphin facilities is now compelling enough to have driven bans across multiple jurisdictions. Conservation arguments for maintaining captive populations are weakened by the limited success of dolphin reintroduction programs and the availability of technology-based cetacean research methods that do not require captivity.
