Sampling Efforts Begin in Chicago Waterway
Fisheries biologists from the Illinois Department of Natural Resources (IDNR) and the U.S. Fish and Wildlife Service (USFWS) will begin intensive sampling operations in multiple locations within the Chicago Area Waterway System (CAWS) this week. The sampling efforts will include using commercial fishing nets and electro fishing gear in an attempt to locate either silver or bighead Asian carp above the U.S. Army Corps of Engineers Electric Fish Barrier System. The sampling operation will also include the use of commercial fishermen and is scheduled to take place in the CAWS over the next 2-3 weeks.
Sampling crews will concentrate their efforts near warm water discharges created by various industrial operations along the waterway system. These areas of warm water serve as a place of congregation for fish during the winter when water temperatures drop significantly.
The sampling effort on the Chicago Area Waterway System is an important step in the Asian Carp Control Strategy Framework, which includes both short and long term actions to stop the migration of Asian carp into the Great Lakes.
