The Welfare of Fish in the Ornamental Trade

The ornamental fish trade moves hundreds of millions of fish annually — with massive mortality rates.

Key Facts

An estimated 1-2 billion ornamental fish are traded globally each year
Mortality rates from collection through retail can exceed 80% for some marine species
Cyanide fishing is used to stun reef fish for collection — causing organ damage
Captive-bred freshwater fish have far lower collection and transport mortality than wild-caught marine fish

Welfare Considerations

The ornamental fish trade is characterized by extremely high mortality at every stage — from collection through transport, wholesale, retail, and the first weeks of home aquarium keeping. For marine fish collected using cyanide, mortality begins immediately as the toxin damages organs. Long transport chains stress fish repeatedly. Retail holding in inadequate conditions depletes immune function. Novice keepers make fatal husbandry errors. The cumulative welfare cost of this mortality — spread across hundreds of millions of fish annually — is enormous and largely invisible.

What You Can Do

Choose captive-bred freshwater fish rather than wild-caught marine species
Research and provide appropriate aquarium conditions before purchasing fish
Avoid purchasing fish showing signs of disease or stress at retail
Support expansion of captive-breeding programs for popular marine species
