TRAVERSE CITY, Mich. – A water sample from Lake Michigan’s Sturgeon Bay in Wisconsin has tested positive for DNA from invasive Asian carp, although it’s unknown whether the genetic material came from a live fish, scientists said Tuesday.
It’s the second positive DNA hit for the feared carp detected in Lake Michigan in recent years, as experts work to determine how far the voracious fish have advanced toward the Great Lakes. A water sample taken in 2010 from the lake’s Calumet Harbor also yielded a positive result.
