New research shows about 90% of marine aquarium fish sold in the US are caught from the wild, not bred in captivity.
The study, led by Dr Bing Lin from the University of Sydney, found most fish come from the western Pacific and Indian oceans.
Globally, around 55 million marine animals are sold each year in an industry worth over US$2 billion, with the US driving two-thirds of demand.
Researchers found 45 threatened or declining species, including Banggai cardinalfish and clarion angelfish, listed for sale online.
“Much of the trade is opaque — from reef to retail,” Lin said. “Consumers often don’t know where their fish come from.”
Experts warn poorly managed wild capture can harm vulnerable populations and disrupt marine ecosystems.
Stronger traceability, eco-certification, and consumer awareness are needed to make the trade sustainable, the researchers said.
