A new study has found that about 90% of marine aquarium fish sold in the US come directly from the wild.
The research, led by Dr Bing Lin of the University of Sydney, highlights opaque supply chains “from reef to retail.”
Globally, around 55 million marine animals are sold each year, with the US accounting for two-thirds of demand.
Fish such as Banggai cardinalfish and clarion angelfish—both threatened species—were among those sold by major retailers.
“Many threatened species slip through trade rules and still end up on the market,” Lin said.
Researchers warn that unregulated collection from reefs could worsen biodiversity loss and harm local ecosystems.
Experts call for better oversight, eco-certification, and consumer awareness to ensure sustainable sourcing.
“Knowing where your fish comes from matters,” said Dr Marian Wong. “It’s the only way to protect these fragile populations.”
