The Invasive Mussel Collaborative (IMC) announced a remarkable decrease in quagga mussel density in the weeks following experimental treatments at a test site in Lake Michigan near Sleeping Bear Dunes National Lakeshore.

The IMC and partners tested a molluscicide treatment to reduce quagga mussel density on a reef in Good Harbor Bay and saw 95% reduction in mussel density following application of the treatment. The reduction of quagga mussels also led to a significant reduction in nuisance algae at the site.
