Watch as hunters become the hunted in this story of a delicious but damaging invasive predator and efforts to remove them from our fragile reefs. Lionfish released in U.S. waters are ruining these critical resources by eating fish and shellfish that are valuable to you and me, as well as the reefs they live on. Participating in lionfish catching derbies or cookoff competitions are ways you can play a part keeping their numbers down and our reefs invasives-free.
