Be sure to join us for the Florida Keys Lionfish Derby & Festival on Sept. 7-10, 2023! The event includes two days to collect as many invasive lionfish as possible, followed by a family-friendly lionfish festival hosted at the picturesque Postcard Inn Beach Resort & Marina in Islamorada. The festival is open to the public and features lionfish tastings, drink specials, educational demonstrations, games, interactive booths from environmental vendors, live music, and more. Visit for all the details.

Teams of two to four people may register to compete in the derby. Be sure to sign up soon to take advantage of the early bird rate of $75 per team, available until August 10. Registration is available online here. You can also stay up to date on derby info and connect with other teams by joining the REEF Invasive Lionfish Facebook Group.
