The marine aquarium trade captures millions of wild reef fish annually, with significant mortality during collection, transport, and captivity. Welfare reform is overdue.
The marine aquarium trade imposes a severe welfare cost on wild reef fish at every stage of the supply chain. Cyanide collection causes direct physiological harm and disorientation; handling and packing cause acute stress and physical injury; multi-stage transport in oxygen-supplemented bags causes chronic stress over days; and captive mortality from inappropriate tank conditions causes prolonged suffering. The 80% one-year mortality estimate means that for every fish displayed in a home aquarium, four or five others have died along the supply chain. This is a welfare catastrophe largely invisible to consumers who see only the final, healthy-looking fish in pet stores. Reform requires both consumer education and regulatory intervention in source countries.
