Fish Welfare in the Aquarium Trade

The global aquarium trade involves millions of fish annually, with wild capture and poor conditions causing significant welfare problems at every stage.

Key Facts

Over 30 million freshwater and 11 million marine fish are traded annually
Up to 80% of marine aquarium fish are wild-caught using cyanide on some reefs
Transport mortality can be extremely high in poorly regulated trade
Many popular aquarium fish have complex social and environmental needs
The trade has contributed to declining populations of clownfish and other popular species

Welfare Considerations

Fish suffer during capture, transport, and often in under-sized aquaria that cannot meet their environmental and social needs. Cyanide stunning causes internal organ damage. Providing appropriate tank size, water chemistry, social grouping, and environmental complexity is essential for captive fish welfare. Captive-bred fish sourced from reputable suppliers are preferable.

What You Can Do

Research fish needs thoroughly before purchasing
Choose captive-bred fish from reputable suppliers
Avoid species known to be collected using cyanide
Ensure aquarium size and water parameters meet species requirements
Consider rescuing unwanted fish rather than purchasing new ones
