RIVER ALLIANCE OF WISCONSIN: Gambusia infestation- Sugar River

The River Alliance of Wisconsin intends to test a technique to mechanically remove as many exotic Gambusia (mosquitofish) as possible from the slough where their population expanded this past summer. The goals of the project are to test this method of sequentially blocking sections of the slough from the mouth to the top, shocking, collecting, and netting, in a repeated fashion), and actually removing as many of these destructive fishes as possible in order to create a more favorable habitat for the return of the native topminnows. Without this action, the return of the native species would highly improbable after this drought year, which dried up most of their habitat in this and other river systems. Final results will be presented to DNR in a report, and via poster at the UW-Platteville poster day by another partner in the project from the UW.
