LA CROSSE, Wis. – The Wisconsin Department of Natural Resources (DNR) alongside neighboring state and federal agencies are conducting an intensive invasive carp removal effort in Pool 8 of the Mississippi River near La Crosse Oct. 25-29.
The Wisconsin DNR is working with the Minnesota DNR, the U.S. Geological Survey (USGS) and the U.S. Fish and Wildlife Service (USFWS) using the innovative Modified Unified Method (MUM). This is the second time MUM has been used in Wisconsin or Minnesota waters. Thirty-four silver carp were captured in Pool 8 (La Crosse and Vernon Co.) during the first interagency carp removal operation in April.
There will be no impacts to commercial or recreational boat traffic on the main channel of the Mississippi River.
Developed by the USGS, the MUM method uses block nets to create compartments or “cells.” The USGS then uses electrofishing boats and boats outfitted with underwater speakers to herd carp from each cell. When a cell is cleared, another net is used to close the cell and prevent the fish from returning.
