DNR, partners haul in a record number of invasive carp

MISSISSIPPI RIVER, Minn. (FOX 9) – The Minnesota Department of Natural Resources (DNR) announced their largest capture of invasive carp with 323 fish caught near Trempealeau, Wisconsin on Thursday.

The invasive carp were caught in Pool 6 on the Mississippi River by contracted commercial fishers.

“Tagging and tracking of invasive carp by the DNR and its partners is working and leading to the successful removal of fish in Minnesota,” DNR Invasive Carp Coordinator Grace Loppnow said in a release. “Wisconsin DNR crews located six tagged invasive carp in Pool 6 last week. Those detections, along with observations by our contracted commercial fisher, led to the successful removal of these invasive carp.”

The DNR said that they will continue to track and catch as many fish as they can as long as river conditions allow it.

“While it is certainly concerning that we have captured this large number of invasive carp in Pool 6, it is likely that these adult fish moved upstream from other locations and were not the result of reproduction in Minnesota waters. DNR will continue to evaluate the data and work with its partners to learn everything we can, while we also work to remove additional fish,” Loppnow said.

The DNR says their data shows the invasive carp moving into the Mississippi during the 2023 spring flooding. They believe the high water conditions allowed them to move upstream past open dams.

Invasive carp were introduced to the Mississippi in the 1970s. They can be a danger to boaters and crowd out native fish.

Keep up the good fight.

A low flow, mild Winter with absolutely no flooding in the Spring is probably nature’s best defense to these things establishing populations further upstream.

I wonder where they are targeting netting them ? From my experience on the MO river, they hate hate current, and any little backwater stagnant water they love. They could be a bigger problem then they realize if they arent targeting this kind of water.

They end up in bays and other slack water areas.

“The Modified-Unified Method, (MUM) developed by the USGS, uses block nets to create compartments or “cells” from which the fish can be driven. Participants then use 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. This process is repeated one cell at a time, gradually reducing the area available to the carp and concentrating the fish into a harvest removal area, where a large commercial seine will be used to draw out the congregated fish. Native fish do not seem to respond as strongly as the invasive carp, preferring to hide, rather than run, from the sound stimulus.”

Very interesting . Thank you . I’d love to be a part of that once .
