![]() ![]() There’s Pacific salmons in all of the Great Lakes as well as steelhead. There’s snakeheads in the Potomac River and canals of Broward County, Florida. There’s lionfish devouring the reef fish of the U. According to the report, no additional snakeheads have been sighted since these operations, including a post-treatment survey conducted in January.There’s Asian carp in ‘tribs’ of the Mississippi River threatening the Great Lakes. FWC biologists removed several hundred snakeheads in late 2020 and early 2021 in a successful eradication effort. Should I be worried about snakeheads spreading? The two populations are nearly identical, and both share a strong genetic relation with snakeheads from the Mae Klong river basin in Thailand.ĭue to the bicoastal geography, researchers believe the snakeheads in Manatee County are likely the result of human transport between sites rather than natural animal migration. Scientists compared features of the godlike snakeheads found in Manatee County to those found in Broward County in 2000. While snakeheads are known to move over land, their ability to feed while doing so emphasizes the fish’s potential negative impact. When the fish were within striking distance, they leaped onto their prey, rapidly twisting their upper body in the direction of the frog and drowning them underwater for a successful catch. According to the study, several snakeheads slithered onto the grassy pond bank, lured by green tree frogs hopping along the water's edge. Local snakeheads were observed hunting frogs, a behavior rarely seen in the wild. “Most never become invasive, but some do.” “Any reproducing non-indigenous species has the potential for deleterious effects on the environment to which it has been introduced,” said Robert Robins, ichthyology collection manager at the Florida Museum of Natural history and co-author of the study. The predatory fish are exceptionally strong - able to withstand diverse environmental conditions including drought. Are goldline snakeheads harmful to our local ecosystem? There were no confirmed sightings or evidence of snakeheads in any other waterways outside of the pond, according to the study. Field scientists completed numerous visual surveys by hand or boat electrofishing, finding the fish most often along the pond’s perimeter and vegetation. Officials with the Florida Fish and Wildlife Conservation Commission captured nearly 400 snakeheads from June 2020 - the initial discovery - through May 2021. ![]() More: Manatee County teachers close class libraries, fearing prosecution under new Florida law ICYMI: Reporter's notebook: Covering Hurricane Ian created a whirlwind of emotion for me The snakeheads were captured at a large, unnamed freshwater pond located in the Williams Creek watershed, a tributary of the Braden River. Snakeheads are native to Myanmar and western Thailand but were introduced to the wild worldwide for their popularity in ornamental fish trades and sport fishing. This is the first documented occurrence of the suave-named goldline snakehead fish in Gulf Coast waters. An aggressive, airbreathing, frog-killing fish was discovered living in a Manatee County freshwater pond, according to a recent study from the University of Florida’s Museum of Natural History. ![]()
