Their dorsal spines and zebra-like bodies may draw one in for a closer look. Commonly used in aquariums for show, the invasive lionfish has made its way from the South Pacific and Indian Oceans to the east coast. In the past decade, they’ve been rapidly expanding from Florida to North Carolina, as well as the Caribbean.

Lionfish may live longer than 15 years and reach sizes exceeding 20 inches. Their venomous spines are capable of fending off predators and stinging humans, according to the Reef Environmental Education Foundation (REEF), an active organization of divers and marine enthusiasts. Lionfish reproduce throughout the year, nearly every four days, and females can spawn over 2 million eggs per year.

Lionfish are venomous and have up to 18 needle-like spines.  However, the meat of the lionfish is not poisonous. If stung, the National Oceanic and Atmospheric Administration (NOAA) recommends treating a puncture wound by immersing it in hot water for 30-90 minutes, and seeking medical attention as soon as possible. The Poison Help Hotline at 1-800-222-1222 is available 24 hours a day.

Coral reef community population structure and dynamics are at risk as a result of the influx of lionfish. These predators out-compete other species such as fish and invertebrates for food resources and they have few known predators, according to NOAA’s Coral Reef Information System (CORIS) website.

NOAA’s experts believe that lionfish populations will continue to grow and are unable to be controlled with conventional methods. Lionfish are established along the southeastern coast of the United States, Bermuda, the Bahamas and throughout the Caribbean.

The Florida Fish and Wildlife Conservation Commission recently waived the recreational fishing license requirement to harvest lionfish. The change allows divers to easily assist in the control of the lionfish population. This will allow people to take as many of the invasive fish as possible.
NOAA and the United States Geological Survey (USGS) as well as professional and recreational diving communities are working to help remove and control lionfish. The Florida Fish and Wildlife Commission encourages people to remove lionfish; they can be speared, caught in hand-held nets or caught on hook and line. Lionfish can be reported to REEF’s

online reporting form.
