How do you measure the success of a lionfish tournament? How about with the 163 lionfish divers brought out of the Florida Keys National Marine Sanctuary last weekend for the 2nd Annual Marathon Lionfish Tournament hosted by Sanctuary Friends Foundation of the Florida Keys. The invasive lionfish, caught from 6-feet of water to 200-feet depths, were counted, then cooked for dinner at Castaway Waterfront Restaurant. The largest lionfish was 17 inches, and the smallest was less barely 3 inches. The biggest actually left his lunch of two reef fish at our feet, showing how devastating just one lionfish can be to our precious reef.
