Marine Animal Welfare

Coral Reef Fish Welfare and Trade

The marine aquarium trade collects millions of coral reef fish annually. Collection methods including cyanide poisoning cause significant welfare harm.

Key Facts

An estimated 11-20 million coral reef fish are collected for the aquarium trade annually
Cyanide stunning, though illegal, is still used in some collection fisheries to stun fish without net damage
Cyanide exposure damages liver and internal organs, causing delayed mortality in collected fish
Net collection is less harmful but requires greater skill and has lower yields per dive
Captive-bred marine fish have dramatically better welfare outcomes and do not deplete wild populations

Welfare Considerations

The marine aquarium trade causes welfare harm at collection, transport, and retail stages for wild-caught fish. Cyanide poisoning causes chronic internal damage that kills fish days to weeks after collection, giving the appearance of live healthy fish at point of sale. Choosing captive-bred or responsibly wild-caught species from transparent supply chains dramatically reduces this welfare harm.

What You Can Do

Ask aquarium retailers about whether fish are captive-bred or net-caught before purchasing
Choose captive-bred marine fish whenever available for your aquarium
Support certification programs for sustainably and humanely collected wild marine fish
Avoid purchasing marine fish from retailers unable to verify their collection supply chain
