Another search of a lake close to Lake Michigan has failed to find Asian Carp. The invasive carp could threaten native Great Lakes fish populations.
Fishermen spent three days last week sweeping a six mile stretch around Lake Calumet, near Chicago. The result: 6,300 fish caught, 30 different species, but no Bighead or Silver carp.
It’s the second time this year that teams led by the U.S. Department of Fish and Wildlife, the Army Corps of Engineers, the Illinois Department of Natural Resources and other agencies, have scoured the waterway looking for Asian carp.
Neither search turned up any carp. The searches were prompted by the discovery of carp eDNA in the lake, which is beyond electric barriers downstream. Those barriers are intended to prevent the carp from reaching the Great Lakes.
A spokesman for the Illinois DNR says the Asian Carp Regional Coordinating Committee will continue to use the eDNA test as an early warning signal, even though the positive tests may be linked to boats dumping bilge water from carp infested waters downstream and not from live Asian carp.
