The northern snakehead is an extended, blotchy-patterned fish that can breathe on land and go backward and forward on the ground by means of wriggling its slippery physique. however these may now not be the species’ most nightmarish features. Snakeheads have a voracious appetit; they’ve been recognized to chow down no longer simplest on different fish, but also crustaceans, reptiles, mammals and small birds. they’re invasive to the U.S., threatening to displace native species and upset the soundness of aquatic ecosystems. The fish had been talked about in further than a dozen states throughout the nation and, as Christine Hauser experiences for the new york times, they’ve now been found out for the primary time in Georgia.
The slithering species was as soon as first noticed by means of using an angler fishing in a pond in Gwinnett County. And Georgia officers have issued blunt directions to someone else who stumbles upon a northern snakehead: “Kill it right away.”

After the fisherman alerted Georgia’s natural world gadgets Division to the unusual creature he had revealed, officers obtained all the way down to the pond to analyze. They found an adult snakehead—most definitely the one the fisherman had reeled in after which tossed again into the water—and three juveniles. those snakeheads are actually “[d]ead and frozen,” a fisheries operations supervisor with the flora and fauna resources Division, tells Hauser.
Snakeheads are native to Asia, Malaysia, Indonesia and Africa, the place they exist in freshwater ecosystems with the right balances to deal with the fish in test. In decades previous, snakeheads had been offered in pet retail outlets and are living food markets in the usa, and are believed to were launched into natural waters via “aquarium hobbyists or these hoping to determine a local meals useful useful resource,” according to the U.S. Geological Survey.

the primary based snakehead inhabitants took dangle in Maryland in the early aughts, and the animals can now be found “in each and every main tidal river of the Chesapeake Bay,” experiences Lateshia Beachum of the Washington put up. In 2002, the fish were delivered to the checklist of injurious natural world underneath the Lacey Act, which in flip banned the import and interstate transport of snakeheads.
“These fish are like one thing from a nasty horror movie,” former Secretary of the inner Gale Norton said when proposing the ban some 17 years previously. “they may be able to devour just about any small animal of their course. they can go from side to side during land and live out of water for no less than three days. They reproduce quick. they have got the prospective to lead to big harm to our precious enjoyment and industrial fisheries.”
on the other hand regardless of legislative efforts to control them, 4 species of snakeheads have cropped up in 15 states, from new york to California—and even Hawaii. It’s not clear how the fish have been supplied to Georgia, then again the state’s division of pure resources notes that “[i]nvasive species are continuously offered through unauthorized liberate” and deals a pleasant reminder that “it’s unlawful to import, transport, promote, swap, or possess any species of snakehead fish with out a sound wild animal license” in Georgia.
Robinson tells Hauser of the occasions that consultants now plan to habits genetic attempting out on the four snakeheads captured inside the Georgia pond to appear if the juveniles are related to the adult. at the least one different guardian, officials imagine, may be still swimming free.
