Zoo Animal Welfare

Zoo Marine Mammal Reform

Progress and ongoing challenges in zoo and aquarium marine mammal welfare reform, including cetacean display phase-outs and pinniped management.

Key Facts

Several major marine parks have phased out or reduced cetacean display programmes
SeaWorld's 2016 orca breeding ban followed public and regulatory pressure
Pinniped (seal and sea lion) welfare in captivity is less controversial but still requires attention
Marine mammal training using positive reinforcement is now industry standard
Sanctuaries for former display marine mammals are limited but growing in number

Welfare Considerations

Marine mammal welfare reform in zoological facilities has progressed significantly, driven by documentary evidence of animal suffering and sustained public pressure. The phase-out of orca breeding and theatrical performances represents meaningful welfare progress. However, the welfare of large marine mammals in captivity remains inherently challenging, and the development of genuine sanctuary alternatives for former display animals represents an important frontier.

What You Can Do

Avoid marine parks that use cetaceans for theatrical performances
Support marine mammal sanctuary development as an alternative to captive display
Advocate for retirement of current display marine mammals to enhanced sanctuary environments
