What problems are lionfish causing?

Invasive lionfish threaten native fish and the environment in U.S. Atlantic coastal waters. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.

Why do lionfish destroy reefs?

They have no natural predators in these waters and are thusly becoming rapidly overpopulated and depleting resources, out-competing every other native fish in the Western Atlantic Ocean, Gulf of Mexico and the Caribbean Sea and wreaking havoc on the ecosystem ecologically, environmentally and economically.

How do lionfish impact the environment?

Impacts. Lionfish are a predatory reef fish. They eat native fish, which can reduce native populations and have negative effects on the overall reef habitat and health as they can eliminate species that serve important ecological roles such as fish that keep algae in check on the reefs.
