Aquarium Fish Capture Welfare | Animal Welfare Hub

The capture of wild marine fish for the aquarium trade causes high mortality and welfare harm that starts at the point of collection.

Key Facts

An estimated 98% of marine aquarium fish are wild-caught
Cyanide stunning — illegal but widely practiced — causes organ damage and delayed mortality
90% of tropical marine aquarium fish originate from the Philippines and Indonesia
Mortality between capture and retail sale averages 40-80% depending on species and supply chain
Captive breeding of common marine aquarium species has been achieved for relatively few species

Welfare Considerations

The welfare harm of wild marine aquarium fish capture begins at the point of collection, where cyanide use causes internal damage that kills fish over days to weeks after apparent recovery. Surviving fish endure lengthy transport chains with high stress and mortality before reaching retail. Consumer demand for wild-caught marine fish for aquariums drives habitat damage through cyanide application and drives collection pressure on already vulnerable reef ecosystems. The availability of captive-bred alternatives for increasing numbers of species makes the welfare case for wild collection increasingly difficult to justify.

What You Can Do

Only purchase captive-bred marine aquarium fish where available
Research origin and collection methods before purchasing marine fish
Support organizations promoting captive breeding in the marine aquarium industry
Advocate for cyanide testing requirements at import for marine aquarium fish
Reduce marine aquarium keeping unless you can verify ethical supply chains
