Last month, 14 teams of scuba divers took to the water and collected 1,527 invasive lionfish during the 15th annual REEF Florida Keys Lionfish Derby & Festival. Teams fished from sunrise to sunset on Friday, Aug. 16 and Saturday, Aug. 17. On Saturday evening, derby participants and the public gathered at Florida Keys Brewing Company for Invaders on Tap, a lionfish awareness celebration and social with live music, educational activities and games, and lionfish tastings.

KEY LARGO, FLA. – Last weekend, 13 teams of scuba divers took to the water and collected 1,618 invasive lionfish during the 2025 Florida Keys Lionfish Derby & Arts Festival, hosted by Reef Environmental Education Foundation (REEF). Teams fished from sunrise to sunset on Friday, April 25 and Saturday, April 26.
Eighteen teams of scuba divers took to the water and collected 919 invasive lionfish during the 2022 REEF Florida Keys Lionfish Derby & Festival. Teams fished from sunrise to sunset on Friday, Sept. 9 and Saturday, Sept. 10. The event concluded on Sunday, Sept. 11 at Postcard Inn Resort & Marina in Islamorada, with an outdoor festival featuring lionfish tastings, cooking and dissection demos, games, interactive booths, and live music.

If you haven't checked out the 2016 REEF Trips schedule yet, now's the time. We have an exciting lineup of destinations planned, and we hope you will join us. These trips offer a great introduction to fish identification for novice fishwatchers, and are a fun way for experienced surveyors to build their life-list while interacting with fellow ocean enthusiasts. We are also offering three of the ever-popular Invasive Lionfish Research Studies trips.
REEF, in collaboration with the University of Virgin Islands and Buck Island National Monument, took a major step last week in a novel study to better understand lionfish movement and factors that may influence that movement. The study, focusing on a 2km area of patch and continuous reef in St Croix, used innovative underwater tagging techniques pioneered by REEF to surgically implant transmitters into invasive lionfish within an array of receivers, allowing the team to pinpoint movement of the fish over the next year.
This article highlights the collaborative efforts of conservationists throughout the Gulf of Mexico and western Atlantic who work to combat the invasive lionfish, including REEF's work to orgnanize removal events such as the Florida Keys Lionfish Derby & Festival.
This seminal publication was created by REEF and our collaborators at NOAA, ICRI, the United Nations Environment Programme, Caribbean Environment Programme, SPAW-RAC, and the over 40 participants of the 2010 Caribbean Regional Lionfish Workshop. The guide provides best practices for lionfish control and management, including control strategies, outreach and education, research, monitoring, legal considerations, and ideas for securing resources and partnerships.
Join REEF staff Dr. Alli Candelmo for an update on current research findings of the invasive lionfish in the Tropical Western Atlantic.

In this early paper, staff from REEF and NOAA studied feeding ecology of the invasive lionfish (Pterois volitans). The authors collected stomach content data from fishes taken throughout the Bahamian archipelago. Three relative metrics of prey quantity, including percent number, percent frequency, and percent volume, were used to compare three indices of dietary importance. Lionfish largely prey upon teleosts (78% volume) and crustaceans (14% volume).
This article highlights some of the ways that the Upper Keys community has adressed the invasive lionfish, including REEF's 8th Annual Earth Day "Locals" Lionfish Derby held on April 23-25, 2021 in Key Largo.
