First sighted in Lebanon in 2012, invasive lionfish have since become well-established in the Mediterranean Sea. In an effort to provide policy recommendations for the lionfish invasion within the Mediterranean Sea, REEF joined in a global collaborative effort with researchers from Europe, Asia, Africa, North America, and the Caribbean to share successes and failures from two decades of lionfish management in the Western Atlantic.
REEF Fishinars are fun, live, interactive webinars, open to anyone who wants to learn about ocean life. We hope you can join one of our upcoming sessions!

Last month, 22 teams of scuba divers took to the water and collected 1,898 invasive lionfish during the 14th Annual REEF Florida Keys Lionfish Derby & Festival. Derby teams fished from sunrise to sunset on Friday, Sept. 8 and Saturday, Sept. 9. On Sunday, Sept. 10, participants gathered at Postcard Inn Beach Resort & Marina in Islamorada for a community celebration. The festival featured lionfish tastings, cooking and dissection demos, games, interactive booths, and live music.
KEY LARGO, FLA. – In spite of Tropical Storm Sally’s unexpected appearance over south Florida, 23 teams took to the water this weekend, bringing in a total of 1,321 invasive lionfish during the 2020 Upper Keys Lionfish Derby; the most fish ever harvested at a REEF Lionfish Derby held in the Florida Keys. Teams were permitted to fish anywhere in Florida, from sunrise to sunset on Friday, Sept. 11 and Saturday, Sept. 12. More than $4,000 in cash and prizes was awarded to teams who brought in the most, largest, and smallest lionfish.
For the first three weeks in July, REEF’s Invasive Species Program Manager, Dr. Alli Candelmo, and Lead Intern for the Invasive Species Program, Madalyn “Moose” Mussey, have spent almost every day underwater conducting lionfish research. With the help of Forever Young Charter Company, Tony Young, Jeff Leonia, REEF staff, and volunteers, REEF has been assessing lionfish densities in deep water habitats off Islamorada, FL. Along with habitat surveys, the team has deployed a hydrophone (which records underwater sounds including fish sounds) in a site with high densities of lionfish.
Despite a summer with very little Lionfish Derby action, our Invasive Species Program has been keeping busy with plenty of projects, including several grants that we have recently been awarded to support our ongoing lionfish work. First, we're excited to share that REEF has been awarded $299,087 through NOAA's Saltonstall-Kennedy Competitive Grants Program, to study the effectiveness of lionfish traps on deep reefs in the Florida Keys.
Last weekend, 13 teams of scuba divers took to the water and collected 1,618 invasive lionfish during the 2025 REEF Florida Keys Lionfish Derby & Arts Festival. Teams fished from sunrise to sunset on Friday, April 25 and Saturday, April 26. The derby weekend concluded on Sunday, April 27 at the REEF Campus in Key Largo, with a festival celebrating the intersection of art, science, and marine conservation. The festival included lionfish scoring, cooking and dissection demos, plus numerous educational activities, games, and vendor booths.
