Invasive Asian Carp DNA Found in Lake Michigan

CHICAGO, Jan. 20 (UPI) — Asian carp DNA has been found in Lake Michigan for the first time, raising invasive species fears, tests indicate.

Testing conducted by the Illinois Department of Natural Resources turned up a positive match for Asian carp DNA in the lake’s Calumet Harbor, while another positive DNA sample was detected about a half mile away in the Calumet River, The Chicago Tribune reported Wednesday.

News of the findings came a day after the U.S. Supreme Court rejected a request by the state of Michigan to force Illinois to close Chicago-area navigational locks and dams to keep the voracious carp from entering Lake Michigan and possibly damaging its ecosystem.

“We’ve been sitting on our hands for two months. It’s no surprise that these fish continue to move toward Lake Michigan,” Joel Brammeier, president and chief executive of the Alliance for the Great Lakes, told the Tribune. “We’re at that tipping point right now where the balance is still in our favor to stop Asian carp from getting in. But the longer we wait, the more that tips in the other direction.”

Army Corps of Engineers Maj. Gen. John Peabody told the newspaper biologists are still analyzing the DNA findings.
