The captive orca industry, largely abandoned in North America following public pressure, exemplifies how welfare science can drive cultural and policy change in zoo animal keeping.
The captive orca story demonstrates both the welfare harm possible in large-scale zoo operations and the capacity for cultural and policy change when welfare science reaches the public. Orcas in captivity develop stereotypies, aggression, abnormal social dynamics, and dramatically shortened lifespans compared to wild populations. The spatial and social complexity of captive environments cannot approach wild conditions for these wide-ranging, deeply social animals. The campaign that ended orca breeding represents the power of welfare science combined with compelling media to drive institutional change. The ongoing welfare of remaining captive orcas remains a significant concern.
