New white paper on zebra mussel treatment
The Minnesota Aquatic Invasive Species Research Center is pleased to release a new white paper: Treatment options for the eradication of limited-scale zebra mussel infestations at various water temperatures. This white paper is ideal for natural resource managers and agencies, watershed districts, lakeshore associations, AIS consultants, or other entities that are planning or associated with zebra mussel monitoring or the extirpation of newly established and localized zebra mussel populations, particularly in a bay or small body of water. The research that informed this paper, led by Jim Luoma of the U.S. Geological Survey, covers four molluscicides: Zequanox, EarthTec QZ, Postassium chloride (potash), and Niclosamide. It evaluated the molluscicides at four different temperatures – a key difference in Minnesota’s colder waters – and for three different exposure durations. The result is a list of specific treatment recommendations based on size of infestation, ability to hydrologically isolate the area, the non-target animal community, and ambient water temperature.
