An invasive silver carp found 9 miles from Lake Michigan in June somehow made it past three electric barriers designed to prevent the fish from spreading into the Great Lakes, officials announced Friday.
Despite the finding, state and federal officials say the barriers are an effective tool to ward off Asian carp, which includes silver carp.
Local, state and federal agencies are trying to prevent the spread of the invasive Asian carp into the Great Lakes, where it’s feared the voracious fish could devastate the Great Lakes fishery.
Autopsy findings released Friday show the 4-year-old silver carp found in June in the Little Calumet River came from the lower or middle Illinois River. That’s far below the U.S. Army Corps of Engineers’ electric barriers.
