Divers and snorkelers removed 1,518 invasive lionfish from Florida Keys waters during three Lionfish Derby events in 2011. Organized by REEF in partnership with the Florida Keys National Marine Sanctuary, the Florida Keys Lionfish Derby series began in 2010 to engage local communities in addressing the invasive lionfish issue. Goals of the lionfish derby series include raising awareness, educating collectors in safe collecting and handling procedures, providing samples for research, conducting lionfish cooking demonstrations and tastings for the general public, and encouraging ongoing removal efforts throughout the region. Teams of registered divers competed for cash and prizes in the categories of most, largest, and smallest lionfish. Dive teams traveled from as far as Chicago, IL.; Austin, TX; and Sunapee, NH to compete in the derbies. Participants and attendees observed filleting demonstrations and enjoyed tastings of lionfish caught during the event. Researchers from the U.S. Geological Survey, Salisbury University, University of Florida, Loyola University, international researchers from the UK, the State of Florida, and NOAA all utilized samples and data from the derbies to aid in their lionfish research. Growing populations of lionfish off the southeast U.S., Caribbean, and Gulf of Mexico are impacting native marine life commercially, recreationally, and ecologically important species. Derbies are just one of several strategies being employed to help control the lionfish invasion.
