Two federal and one Illinois agency on Friday announced the release of new online maps showing present data on Asian carp in Midwest waterways.
"Asian Carp Distribution in North America" shows the presence of bighead, silver, black and grass carp in the Mississippi and Ohio rivers and the Great Lakes. The data was released by the U.S. Army Corps of Engineers, Illinois Department of Natural Resources and U.S. Geological Survey.
The data was compiled using surveys distributed to biologists, private and non-governmental organizations, the Asian Carp Regional Coordinating Committee's Monitoring and Response Work Group and the USGS Nonindigenous Aquatic Species Database.
