SOUTH CHARLESTON, West Virginia — Water samples taken from the Ohio and Kanawha rivers have tested positive for Asian carp environmental DNA.
Environmental DNA is genetic material released into the environment by an organism.
The West Virginia Division of Natural Resources says the test results aren't proof of the invasive species' presence in the rivers. The DNA could have been transported by boats, birds or other means.
The DNR said Wednesday in a news release that fisheries biologists collected the samples in July from two Ohio River navigational pools in Hancock, Ohio and Brooke counties, and from the Kanawha River in Putnam and Kanawha counties. Samples also were collected from the Little Kanawha River in Wood and Wirt counties.
