The Wisconsin Department of Natural Resources (DNR) in partnership with neighboring state and federal agencies will take further action to reduce the number of invasive carp in the Mississippi River.
Additional actions include increasing commercial netting operations, tracking tagged carp and ongoing use of the innovative Modified Unified Method (MUM), a tactic that involves driving fish towards a series of smaller and smaller areas until they are netted out of the water.
Continued efforts follow a successful second invasive carp removal effort on Oct. 25-29 in Pool 8 of the Mississippi River near La Crosse in which the DNR, Minnesota Department of Natural Resources, U.S. Geological Survey, U.S. Fish and Wildlife Service, Wild Rivers Conservancy and National Park Service sampled more than 100,000 pounds of fish.
Although seven silver carp were observed jumping out of the sampling area, no invasive carp were captured during the October removal using MUM. Thirty-four silver carp were captured during the first MUM operation in the same locations in April.
“This is potentially very good news about the current status of invasive carp in Pool 8,” said Jordan Weeks, DNR Mississippi River Fisheries Biologist. “Invasive carp captures decreased sharply. We’re hopeful this indicates a decrease in the actual invasive carp population.”
