Over 50 Invasive Carp Captured on Mississippi River
The Minnesota Department of Natural Resources is conducting an immediate response to the capture of 51 invasive carp on the Mississippi River. The invasive carp were caught by two commercial fishing operators near La Crosse and Trempealeau, Wisconsin, during routine spring netting in March.

When the commercial fishing operator operating near La Crosse saw what he thought were invasive carp, he contacted the DNR. The DNR invasive carp field crew assisted in removing and identifying the fish. The DNR identified 39 silver carp and 11 grass carp caught in Pool 8 of the Mississippi, just south of La Crosse, and one silver carp caught in Pool 6, about 20 miles farther upstream. All invasive carp recovered have been given to the U.S. Fish and Wildlife Service to determine their age, size and gender.

Previous captures of invasive carp in Minnesota have been individuals or small numbers of fish. This capture indicates an increase in the abundance of invasive carp in the Pool 8 portion of the river between Minnesota and Wisconsin.

Restoring Native Vegetation - Lake Conroe has a volatile history of aquatic vegetation management. Hydrilla infested the reservoir soon after the reservoir filled, resulting in coverage of approximately 10,000 acres by the early 1980’s. To control hydrilla, large numbers diploid grass carp were stocked. Grass carp not only controlled hydrilla, but also eliminated most other aquatic vegetation in the lake and continued to inhibit plant growth into the late 1990’s.
