Shark Welfare in Aquariums

Large shark species in aquariums show poor welfare and high mortality, with some species fundamentally unsuited to captive life.

Key Facts

Great white sharks have never survived long-term captivity
Sharks kept in aquariums show repetitive circling and reduced activity
Aquarium transport causes extreme stress that kills many sharks before display
Some elasmobranchs including bamboo and epaulette sharks adapt reasonably well to captivity
Public aquarium conservation messaging may not justify the welfare costs for large species

Welfare Considerations

Large pelagic sharks require vast open water environments that no aquarium can replicate. Their welfare in captivity is systematically compromised by space constraints that prevent normal behavior. Species selection for aquarium display should prioritize welfare compatibility. Aquariums that refuse to display unsuitable species take the most welfare-responsible position.

What You Can Do

Support aquariums that choose not to display large unsuitable shark species
Advocate for species welfare assessment requirements in aquarium collection decisions
Donate to wild shark conservation rather than captive display
Educate others about the difference between welfare-appropriate and inappropriate captive species
Support research on shark welfare indicators in captive settings
