Aquatic Invasive Species (AIS) are threatening Minnesota waters. Aquatic Invasive Species (sometimes called exotic, invasive, non-indigenous or non-native) are defined by the U.S. Fish and Wildlife Service as: “aquatic organisms that invade ecosystems beyond their natural, historic range. Their presence may harm native ecosystems or commercial, agricultural, or recreational activities, depending upon their ecosystems.” Their presence can be harmful to fish populations, water quality, as well as water recreation.
At this time, there are no known lakes or rivers in Murray County that are infested with these invasives. AIS typically have little-to-no natural predators in their new environment, reproduce very quickly, and are more aggressive than native species. It is illegal to possess, transport, and/or introduce any aquatic plants or animals within Minnesota that are designated as “prohibited and regulated” invasive species by the Minnesota Department of Natural Resources (MN DNR).
