Wild Coral Reef Fish Welfare and Aquarium Trade

Millions of marine fish are captured annually for the aquarium trade using methods that cause acute welfare harm. Understanding the trade helps consumers make informed choices.

Key Facts

An estimated 20-30 million fish are captured from coral reefs annually for the aquarium trade
Cyanide fishing — using sodium cyanide to stun fish — is illegal but widespread in the Philippines and Indonesia
Cyanide causes acute poisoning stress and long-term organ damage in fish that appear to survive
Up to 80% of fish captured with cyanide die within weeks of capture from delayed organ failure
Net capture methods cause injury and stress but are less acutely harmful than cyanide
Captive-bred marine fish are available for many popular species and have dramatically better survival rates

Welfare Considerations

Wild-caught marine aquarium fish experience multiple welfare harms through the collection process. Cyanide exposure — even at survivable doses — causes acute toxic stress and progressive organ damage. Net capture causes physical injury and severe stress from the capture process. Post-capture holding in crowded, unfamiliar conditions with poor water quality causes additional stress and disease. The mortality rate between collection and the aquarium is estimated at 50-90% across the supply chain, meaning the welfare cost per surviving fish is enormous. Captive-bred alternatives provide the same species with dramatically better welfare outcomes.

What You Can Do

Choose captive-bred marine fish for your aquarium — growing numbers of species are now available
Ask aquarium shops about the source of their fish and whether captive-bred options are available
Support the Coral Triangle Initiative and cyanide testing programs in source countries
Never release aquarium fish into the wild — invasive species like lionfish cause ecosystem harm
Consider freshwater aquariums which have much higher rates of captive-bred fish available
