Millions of coral reef fish are captured annually for the marine aquarium trade. The capture, transport, and captive care chain involves significant welfare risks that vary widely between suppliers.
The marine aquarium trade welfare problem is most acute in the capture and transport phase, where high mortality is treated as an acceptable cost of doing business rather than a welfare failure requiring mitigation. Cyanide fishing, where illegal, causes fish to convulse and suffer before collection, and causes hidden internal damage that shortens survival in captivity. Sustainable, net-only capture methods by trained collectors, combined with rapid acclimatisation and high water quality during transport, dramatically reduce mortality and welfare harm. Consumer choice of captive-bred species where available, and purchase from suppliers who verify collection method and chain-of-custody, are the most direct welfare levers available to aquarium hobbyists.
