The latest shot across the bow comes from the U.S. Fish and Wildlife Service, which late last month found two juvenile Asian carp in the Illinois River, 12 miles closer to Lake Michigan than the last time researchers surveyed the waterway. Sampling crews found the two silver carp, each just over six inches long, in the Marseilles Pool of the Illinois River. Researchers with USFWS are not conducting genetic tests to determine how old the fish are and where exactly they spawned. "This finding brings the leading edge of juvenile Asian carp detections about 66 miles closer to Lake Michigan than it was at the beginning of 2015," the Asian Carp Regional Coordinating Committee announced in a news update.
