Shark Welfare in Captivity | Animal Welfare Hub

Sharks in aquarium captivity face welfare challenges from inadequate swimming space, diet modification, stress from handling during transport, and social species held in isolation or incompatible groupings.

Key Facts

Large shark species including great whites have extremely poor captivity survival records
Sand tiger sharks fare better in captivity but require large circular tanks for continuous swimming
Sharks show stress responses to capture and transport that include elevated cortisol and reduced immune function
Social shark species including white-tipped reef sharks benefit from appropriate conspecific groupings
Some facilities have developed sophisticated holding systems that achieve multi-year survival for species previously considered uncaptivatable

Welfare Considerations

Shark captivity welfare varies enormously with species and facility quality. Species that require continuous swimming to ventilate their gills cannot survive in inadequate tank sizes. Transport and capture stress causes immune suppression that predisposes to disease in the first weeks of captivity. The welfare case for captive sharks depends on the ability to provide species-appropriate conditions — a high bar that many facilities cannot meet for large pelagic species and that requires ongoing investment in tank design and husbandry research.

What You Can Do

Evaluate tank size adequacy and species appropriateness when visiting aquaria with sharks
Advocate for captive shark welfare standards in aquarium accreditation
Support wild shark conservation as the preferred approach to shark engagement
Donate to shark welfare and conservation research
Raise awareness about the high welfare requirements and frequent failures of shark captivity
