Quagga mussels eradicated from lake with low doses of ionic copper

This report describes the use of the acid-stabilized ionic copper formulation called EarthTec QZ to treat an entire lake heavily infested with quagga mussels for the purpose of eradicating the invasive species. This is the first recorded instance of a lake-wide eradication effort of quagga mussels and is also the largest and deepest lake known to have been the subject of an effort to completely eradicate either quagga or zebra mussels.

USGS studies zebra mussel control with ionic copper

The USGS is studying zebra mussel control in Lake Minnetonka, Minnesota. The project is a collaboration with the University of Minnesota Aquatic Invasive Species Research Center. If successful, the treatment could provide a blueprint for protecting other lakes infested with zebra mussels.
