Coral Reef Fish Welfare and Capture Methods

The marine aquarium trade captures millions of coral reef fish annually, with cyanide poisoning used in many regions causing organ damage and deferred mortality.

Key Facts

An estimated 20 to 24 million marine fish are sold in the aquarium trade annually
Cyanide fishing is illegal in most countries but estimated to supply 90% of fish from some regions
Cyanide stuns fish allowing easy capture but causes liver and kidney damage leading to death weeks later
The Dory effect after animated films drove spikes in demand for clownfish and blue tangs
Marine Aquarium Council certification requires non-destructive collection methods

Welfare Considerations

Fish captured with cyanide experience the stress of chemical incapacitation, forced capture, and transport, while sustaining internal organ damage that may not manifest for weeks. The deferred mortality rate from cyanide exposure is high, meaning many fish sold appear healthy at purchase but die within months from internal damage. Even fish captured by net experience acute capture stress. The aquarium trade creates demand that incentivizes methods harmful to individual animals and destructive to reef ecosystems.

What You Can Do

Only purchase marine fish from suppliers certified by MAC or CORAL
Research whether your desired species reproduces successfully in captivity
Consider freshwater aquaria stocked with captive-bred species as an alternative
Oppose import of wild-caught marine fish without collection method documentation
