aquatic invasive species (AIS)

Ballast water

Minnesota Trout Unlimited’s efforts to prevent the introduction and spread of aquatic invasive species (“AIS”) via ballast water discharges.

Minnesota Trout Unlimited has been working for many years to prevent the introduction and spread of aquatic invasive species into Minnesota waters.  For years our efforts focused primarily upon Lake Superior and the Great Lakes basin.  This is not just because Lake Superior and the Great Lakes are perhaps the greatest single coldwater fishery in the country, but also because the Great Lakes shipping has been the major source of aquatic invasive species introductions impacting all Minnesota waters.  Zebra mussels, round gobies, and the VHS virus are just some of the many invasive species brought to our shores via Great Lakes shipping activities.

For years MNTU and partners such as Clean Water Action Minnesota, the Minnesota Center for Environmental Advocacy, and the Izaak Walton League, the Minnesota Center for Environmental Advocacy, and Clean Water Action have fought for the adequate regulation of ballast water discharges from all Great Lakes shipping vessels.  Through our work on Asian carp and other AIS we have raised the awareness of additional partners who are now adding their support to our advocacy on proposed federal ballast regulations.
