Why are lionfish invasive in the Gulf of Mexico?

Are lionfish invasive in the Gulf of Mexico?
Their invasive range has expanded through the North Atlantic Basin, Caribbean Sea, Gulf of Mexico, and Guyana Basin21, with densities reported up to c. 0.3 lionfish per 100 m2 on tropical and subtropical natural reefs (NRs)18,19 and >30 lionfish per 100 m2 on ARs19.
How did lionfish get into the Gulf of Mexico?
But when some of those Indo-Pacific natives escaped their glass homes and found their way into the Gulf of Mexico, an invasive superpredator was unleashed, one that has the potential to outcompete and devastate native fish like snapper, grunts and grouper.
Where is the lionfish currently invading?
Lionfish are now invading the Gulf of Mexico and the northern coast of South America. These fish pose a serious threat to reef fish populations across the region, and thus to coral reef ecosystems and the people who depend on them.
What animal eats lionfish?
Lionfish have no natural predators in their invasive range. We’re not entirely certain what eats lionfish in their native range, but it’s most likely large predators like grouper, snapper, eels and sharks.
How is the lionfish population being controlled?
To date, most control efforts have been diver-based and focused on areas with high diver visitation and shallow water. Lionfish removal by divers is considered a promising strategy for local control (i.e., specific reefs or reef areas).
How can we prevent more invasions from lionfish?
Here are the 5 best ideas for stopping the invasive lionfish.
- Hunt Them! Divers Needed.
- Eat Them! They taste like chicken.
- Train Sharks to Eat Them! Yes this is a real thing.

How do lionfish harm the environment?
Science has demonstrated that a single lionfish can reduce native marine creatures by 80% to 90% in its range within just 5 weeks. The native marine species that lionfish are decimating are important for ecological, commercial, traditional and recreational reasons.

Are lionfish a problem in the Gulf of Mexico?
Lionfish continue to expand at astonishing speeds and are harming native coral reef ecosystems in the Atlantic, Gulf of Mexico, and Caribbean. Biologists suspect that lionfish populations have not yet peaked in the Gulf of Mexico, which means that their demand for native prey will continue to increase.
When did lionfish come to the US?
The Invasion. The first lionfish recorded in the Western Atlantic (east coast of the United States, Caribbean Sea and Gulf of Mexico) was a specimen captured near Dania, Florida in 1985. No other lionfish sightings were reported until 1992. The most likely source of these fish was the home aquarium trade.

What is being done about the lionfish problem?
Cooperation and communication among local, state, federal, and international partners is crucial for proper management of lionfish and other widespread invasive species. The Aquatic Nuisance Species Task Force developed a National Invasive Lionfish Prevention and Management Plan (pdf, 69 pages).
