Asian carp may be getting a foothold in waters near Lake Erie according to recent water sample analysis.
From the Pittsburgh Post-Gazette:
“Multiple water samples taken from the Muskingum River last fall carried the environmental signature of bighead carp, an invasive species threatening the ecosystem of the Great Lakes. A report released Friday by the Nature Conservancy — in conjunction with the Muskingum Watershed Conservancy District, the Ohio Department of Natural Resources, and researchers from Central Michigan University — indicated 10 of the 222 samples from the river tested positive for bighead carp eDNA.Asian carp have been established in the Ohio River for more than a decade, but these eDNA results indicate the fish could be present in the Muskingum some 80 miles north of where the Muskingum joins the Ohio at Marietta.The Muskingum has a series of old dams and deteriorating locks, but if the genetic evidence is accurate, those have not provided a significant impediment to the carp moving up the river system.”
