Viral Hemorrhagic Septicemia (VHS) is a fish disease present in some Minnesota waters. It affects some fish species but not others. To prevent the spread of this disease, we have regulations for harvesting and transporting the species that carry VHS.
Species affected by VHS include cisco (all Coregonus, including lake herring and tullibee), smelt (all Osmerus, Spirincus, Hypomesus, and Allosmerus species), as well as certain other species. Currently the only Minnesota waters listed as having VHS are Lake Superior and its tributaries below the posted boundaries, and the St. Louis River downstream of the Fond du Lac dam.
The DNR tested the water bodies listed below for VHS. These lists will be updated as additional water bodies are tested and new information becomes available.[include url="https://webapps17.dnr.state.mn.us/www/faw/vhs-free_water_bodies.jsp"]
