Four silver carp were captured this month in Pool 8 of the Mississippi River near La Crosse.

Rather than kill the destructive invaders, staff with the U.S. Fish and Wildlife Service fitted the fish with acoustic tags and released them back to the river.

On its face, it seems counter to every guidance on aquatic invasive species.

But the action was part of a multi-agency project to monitor the movements of the fish and learn their preferred habitats in the expansive pool.

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.
