Lionfish in the Bay!

This is so not good! Late last month, FWC officer Michael Morrison observed a lionfish swimming off the Laishley Pier in Punta Gorda. This is the third documented lionfish sighting inside Charlotte Harbor, and it’s also the most up harbor. Laishley Pier is actually on the Peace River.

What’s not good about this beautiful fish? Well, for starters, it doesn’t belong here. Lionfish are native to the Indo-Pacific, but unfortunately they are well established throughout the Gulf of Mexico, the Atlantic to North Carolina, and the Caribbean.

The lionfish established here comprise two species, Pterois volitans, the red lionfish and P. miles, the devil firefish. The lions share, 93 percent of those established, are red lionfish. Genetic studies indicate that lionfish in the Atlantic are likely all descendants of a few individuals, which is consistent with the widely held belief that lionfish were introduced into the Atlantic as a result of accidental or deliberate release of aquarium pets. Isolated lionfish sightings were first documented in southeast Florida in the 1980s, and by the early 2000s they were established in that area. They then expanded to the Bermuda (2004), the Bahamas (2005), the Turks and Caicos (2008), the Cayman Islands and the Florida Keys (2009) and the Gulf of Mexico (2010). Today, they are a common sighting on any reef, in the listed areas — natural or manmade, including those off southwest Florida.

Salty Topics: A Thorny Matter: Invasion of the Indo-Pacific Lionfish in the Western Atlantic

lionfishInvasive Indo-Pacific Lionfish were introduced by aquarium hobbyists to waters off the southeast coast of Florida in the 1980s.  Over the past ten years, these beautiful, ornate fish have rapidly spread across the entire tropical western Atlantic, from North Carolina to Venezuela, throughout the Caribbean and the Gulf of Mexico.  The population sizes in the invaded range commonly exceed those from their native habitats by several orders of magnitude.  With a seemingly insatiable appetite for our native fishes, and a lack of local predators and disease to keep them in check, Lionfish can have detrimental effects on the invaded marine ecosystem.  In this talk, we will review the history of the invasion, discuss the biology and ecology that has allowed them to be so successful, highlight some damaging impacts they can have, and finish with what scientists are doing to combat the problem.

On Thursday, March 3rd, UF/IFAS Extension, Florida Sea Grant at Weedon Island Preserve welcomes Dr. Chris Stallings, University of South Florida College of Marine Science, to present “Salty Topics: A Thorny Matter: Invasion of the Indo-Pacific Lionfish in the Western Atlantic”. The educational program is intended for adult and high school age audiences.
