Divers will return to Florida Keys waters next month on a mission: net thousands of dollars in cash and prizes while protecting the environment from invasive lionfish. REEF and the Florida Keys National Marine Sanctuary are hosting the second annual lionfish derby series starting May 14, in Long Key, Fla. In 2010, the inaugural series of lionfish derbies removed 664 of the Pacific invaders from sanctuary waters. “Anyone who appreciates the diversity of the Keys coral reef should be concerned about these invasive fish,” said Sean Morton, Sanctuary Superintendent. “Divers have been actively engaged in lionfish removal in the Keys since 2009 and these tournaments are a way to reward them for their dedication to the reef.” Researchers will collect samples from lionfish caught at the derbies to learn more about lionfish genetics, growth, and impacts to native marine life. Each tournament also includes a detailed awareness and training briefing and lionfish tasting. In addition to the derby on May 14, two other events will be held later this year -- August 20 at Coconuts Restaurant in Key Largo and November 5 at Hurricane Hole Marina in Key West.
