Ultimately, it is hoped the "Judas" fish will reveal the location of other silver carp and guide netting efforts to remove the undesirable fish before they can strengthen their foothold in the Mississippi River along Wisconsin's western border.

The silver carp were caught by commercial fishermen contracted by the Minnesota Department of Natural Resources to look for the invasive fish. Other partners in the project are the Wisconsin Department of Natural Resources, U.S. Geological Survey and USFWS.
