Outline I. Physical description II. Background information A. native waters B. Introduction to the East Coast III. Management issues

The Lionfish (Pterois volitans) Can achieve length of 17 inches Up to 2.5 lbs Distinctive red or maroon and white stripes Fleshy tentacles above the eyes and mouth Fan-like pectoral fins Long separated dorsal spines. Dorsal, anal, and pelvic fins are venomous.

The Lionfish Native to Indo-Pacific waters Occurs on deep ledges and hard bottoms Depths of 85 to 260ft Temperatures of 75-79F Live up to 15 years

Lionfish on the East Coast. Aquarium Trade Florida, early 1990’s Hurricane Andrew Spread to Cape Hatteras, NC by 2000 Gulf Stream Transport of eggs and larvae.

Management Issues Exposure to humans. Few natural predators. Divers Fisherman Non-fatal Few natural predators. Feed on young of commercially important fish. Grouper Snapper Share a food source.

Management NOAA Fisheries and NOAA Ocean Service are using several research techniques to determine extent, range, and population. Eradication UNCW. RV. Cape Fear Large number of adults and juveniles observed established and reproducing along the southeast United States coast. There is further evidence that lionfish numbers are increasing. “There is no getting rid of them now”.
