The WDNR, Minnesota DNR, the U.S. Geological Survey, and the U.S. Fish and Wildlife Service, are all working together to track and remove the invasive fish. They are using a new method called the Modified Unified Method to do so.

“This is the first time the technique has been used in Minnesota or Wisconsin waters,” said Randy Hines, a wildlife biologist and outreach coordinator with the USGS.

The method is adapted from southeast Asian fishing practices, where commercial fishermen will use sounds underwater to herd the carp — native to that part of the world — and use nets to herd them into smaller spaces and then trap them there.
