The USGS and MAISRC have been researching alternative strategies for invasive mussel population control using copper concentrations around 10% of the labelled maximum dose. The research has included two bay-wide treatments in Lake Minnetonka with the goal to reduce settlement of larval mussels thereby reducing recruitment and total population. Research included multi-year monitoring of the zebra mussel population and non-target communities. They also looked at seasonal trends of copper sensitivity in zebra mussels to identify ideal treatment periods. These projects also included public engagement and involvement in part to better gauge stakeholder interests regarding invasive mussel control objectives. The findings highlight potential methods for invasive mussel control alternative to the popular “eradication or bust” strategies.
