Invasive species in Wisconsin waters threaten ecosystem

Inexperienced BAY, Wis. (WBAY) – The Wisconsin Department of Organic Means (DNR) and UW-Extension are inquiring anglers to help stop the distribute of aquatic invasive species in Wisconsin’s lakes and rivers when ice fishing this winter.

Aquatic invasive species have created their way into Wisconsin’s waterways. Continue to, anglers can cut down the transmission of these species even in the winter season by taking away any mud or plant content clinging to their equipment, together with sleds utilised to haul supplies, prior to leaving fishing spots.
