Army Corps, IL DNR, USGS Release New North America Asian Carp Distribution Maps

Bighead Carp
On April 26, the U.S. Army Corps of Engineers, Illinois Department of Natural Resources and U.S. Geological Survey  released new maps depicting "Asian Carp Distribution in North America" for bighead carp and silver carp. The maps display current information on the presence of those invasive Asian carp species at all of their life stages in the Mississippi River, Ohio River and Great Lakes.

"The intent of this succinct, graphical documentation of locations of Asian carp individual captures, as well as areas with established populations, is to be a ‘living resource’ for ACRCC partners, decision makers and the public to access specific, timely information," said USACE Fish Biologist and eDNA Program Manager Kelly Baerwaldt, in a media release announcing the map release.  "The ACRCC continues to take the threat of Asian carp as very real and to conduct intensive monitoring to help determine the threat of this invasive fish," added Baerwaldt.

Silver Carp
Data were collected from responses provided by federal, state, academic, private-consulting and non-governmental organization biologists to an Asian carp questionnaire. Additional data were obtained from the Asian Carp Regional Coordinating Committee Monitoring and Response Work Group, which include data collected since 2009 in detail for the Chicago Area Waterway System and a majority of the Illinois Waterway; and from the USGS’s Nonindigenous Aquatic Species Database.
