Reef Fish Collection for the Aquarium Trade

Millions of wild reef fish are collected annually for the ornamental aquarium trade using methods including cyanide poisoning that cause severe welfare harms and reef ecosystem damage.

Key Facts

Over 30 million reef fish are collected for the aquarium trade each year
An estimated 20-50% of fish caught with cyanide die within 48 hours
Cyanide also kills coral polyps and other invertebrates in affected areas
Marine Aquarium Council certification covers only a minority of traded fish
Up to 80% of aquarium fish sold in the US are wild-caught

Welfare Considerations

Cyanide-caught fish suffer acute chemical toxicity, internal organ damage, and immune suppression. Many die days or weeks after capture from latent cyanide effects. Transport stress, poor retailer conditions, and inexperienced hobbyist husbandry compound the mortality rate. The welfare impacts span millions of individual fish annually.

What You Can Do

Research the origin of fish before purchasing from aquarium retailers
Choose captive-bred fish species whenever available
Support retailers who can verify sustainably collected or captive-bred stock
Advocate for mandatory traceability certification in the ornamental fish trade
Consider species from community-based sustainable collection programs
