Leopard Shark and Small Shark Welfare in Aquariums and Aquaculture

Leopard sharks and other small shark species are kept in public aquariums and sometimes in aquaculture for display or research, with welfare needs specific to their elasmobranchii biology.

Key Facts

Leopard sharks are common along US Pacific coast and relatively hardy in captivity
Kept in public aquariums for education and display worldwide
Some shark species are farmed or held for meat production in Asia
Sharks have electroreceptors and lateral line systems sensitive to electrical and pressure stimuli
Captive sharks frequently develop compulsive swimming stereotypies indicating welfare compromise
Water quality including dissolved oxygen and salinity range is critical for shark welfare

Welfare Considerations

Captive sharks in insufficiently sized tanks develop compulsive circling behaviour indicating chronic welfare compromise. Electroreceptors in shark snouts detect electrical fields including those from aquarium equipment, potentially causing chronic irritation. Insufficient space prevents the natural swimming behaviour essential for gill ventilation in obligate ram-ventilators. Aquarium welfare standards for sharks require specific attention to tank size, water quality, and sensory environment.

What You Can Do

Evaluate aquarium shark exhibits for adequate tank size and enrichment before visiting
Support aquariums with accreditation from BIAZA or AZA that require welfare standards
Avoid shark fin soup and products that drive shark mortality in fisheries
Report concerns about captive shark welfare to aquarium management or Zoo Licensing
Support research into shark welfare indicators in captive settings
Engage with aquarium accreditation bodies about shark-specific welfare requirements
