Predatory fish that walks on land spreads to new US states as officials urge locals to cut their heads off

An invasive land-walking fish from Asia is spreading into new US states, leading officials to ask Americans to take matters into their own hands.The northern snakehead, a predatory fish known for its aggressive behavior and astonishing ability to breathe air and survive out of water for several days.Since first being detected in 2022, the fish has been found in the Mid-Atlantic and on the East Coast, until officials in Missouri recently announced the state's first sighting. Missouri Department of Conservation (MDC) officials recently removed a northern snakehead in Oregon County. MDC Invasive Species Ecologist Angela Sokolowski said: 'This is the first time we have confirmed the presence of this species in the Missouri portion of the Eleven Point, which suggests they are spreading into Missouri from known populations downstream in Arkansas.'Officials are warning anglers not to throw the fish back if they catch one.Because northern snakeheads can breathe air and survive on land for days, simply leaving them on the shore is often not enough to kill them.Instead, the MDC is urging people to 'kill the fish by severing the head, gutting it or placing it in a sealed plastic bag.' The northern snakehead, a predatory fish native to Asia, has earned a fearsome reputation for its aggressive hunting behavior and ability to outcompete native species for food and habitatSo far, northern snakeheads have been confirmed in just two Missouri river systems: the St Francis and Eleven Point rivers, both in the southern part of the state.These waterways connect to areas of Arkansas where the species is already established, giving the fish a natural route to spread into Missouri.No populations have been confirmed in the state's other river systems, but tracking the invasive predator's spread remains important because it can compete with existing fish for resources.'We anticipate negative effects to our aquatic systems, as the invasive fish competes with our existing fish populations for resources,' Sokolowski said in a statement released on September 28. 'Snakeheads are predatory fish and will likely prey upon our native and sport fish, such as smallmouth bass, potentially causing direct negative impacts to populations.'Often dubbed the 'Frankenfish,' the species was reported in New York back in June.The alarming discovery was made at Lily Pond in Suffolk County on Long Island, where a fisherman reeled in one of the snake-like predators, prompting New York's Department of Environmental Conservation (DEC) to step up efforts to stop the species from becoming established in the state. Heidi O’Riordan, the regional fisheries manager for the New York State DEC, told CBS News: 'They don’t belong, they don’t have a natural predator, they will screw up our native fish populations, they tend to eat pretty much anything they can put in their very large mouths.' Since first being detected in 2022, the fish has been found in the Mid-Atlantic and on the East Coast, until officials in Missouri announced the state's first sighting (stock) While the northern snakehead may look like an ordinary fish at first glance, wildlife officials warn it poses a serious threat to native ecosystems.The invasive predator reproduces at an alarming rate, with females capable of laying up to 15,000 eggs at a time and spawning as many as five times a year. Those eggs hatch within just a few days, allowing populations to grow rapidly once the species becomes established.Its appetite is equally concerning. As a top predator, the snakehead feeds on fish, frogs, crayfish and other aquatic animals, disrupting the natural balance of waterways and competing with native species for food.'This species is of concern because it is a top predator and disrupts the natural aquatic feeding structure in ecosystems,' the New York Invasive Species Information program states.Snakeheads are typically found in freshwater ponds, wetlands, rivers and slow-moving streams, particularly in areas with stagnant water.The fish is easy to recognize thanks to its snake-like appearance. It has a long, slender body, an extended dorsal fin running nearly the length of its back and a mottled brown pattern that resembles a boa constrictor. Fully grown adults can reach about three feet in length.The species has continued expanding its footprint across the US in recent years.Before the New York discovery, sightings had been reported in states including Arkansas, Connecticut, Delaware, Florida, Georgia, Illinois, Louisiana, Maryland, Maine, Mississippi, Missouri, New Jersey, North Carolina, Pennsylvania, and Virginia, and the District of Columbia.
