Coral Reef Fish Welfare in the Ornamental Trade

The ornamental fish trade supplies millions of wild-caught reef fish to the aquarium hobby globally, with welfare concerns at every stage from capture through retail.

Key Facts

Over 30 million marine fish are traded annually for the ornamental market
Cyanide poisoning for fish capture causes tissue damage, liver failure, and high post-capture mortality
Clownfish and dottybacks are successfully captive-bred, reducing wild capture pressure
Mortality rates during transport and retail can exceed 50% in poorly managed chains
The Marine Aquarium Council developed certification standards for sustainably sourced fish

Welfare Considerations

The ornamental marine fish trade involves welfare harms at every stage of the supply chain. Cyanide capture - still widely used in parts of Southeast Asia - stuns fish for easy capture but causes progressive tissue damage and eventual death in many survivors, meaning mortality continues for weeks after capture. Transport stress from overcrowding, temperature fluctuation, and ammonia accumulation causes additional mortality. At retail, fish in inadequately cycled tanks face ongoing stress and disease exposure. Choosing captive-bred fish where available, and wild-caught fish only from certified sustainable sources, reduces welfare harm in this sector.

What You Can Do

Choose captive-bred marine fish where they are available, including clownfish and dottybacks
Only purchase wild-caught fish from retailers that can demonstrate certified sustainable sourcing
Ask retailers whether their fish are cyanide-caught and refuse to purchase if confirmation is unavailable
Support expansion of marine fish captive breeding programmes
Avoid impulse purchases of marine fish without researching their welfare needs in captivity
