The marine aquarium trade captures millions of wild reef fish annually, with high mortality rates during collection, transport, and early captivity.
The marine aquarium trade imposes enormous welfare costs on wild fish populations. Fish collected with cyanide experience toxic injury, and the transport chain from tropical reef to retail aquarium involves repeated stress events and high mortality. The fish that reach retail tanks have already survived multiple welfare challenges that many of their cohort did not. Transitioning to captive-bred stock wherever possible is the most important welfare and conservation improvement available to the marine aquarium hobby.
