Zebra Mussel Control Method Research Program

Agency: U.S. Geological Survey

Location: Wisconsin

Treatment Type: Other, Toxicant

Treatment Method Used: Carbon Dioxide, Pseudomonas Fluorescens

USGS has been actively engaged in evaluations of different control methods since 2011. Experiments and sampling are performed in the laboratory as well as in field trials. The program includes evaluation of both target and non-target impacts, particularly on native unionids.

The research program is also working to identify the best treatment protocols as a rapid response for zebra mussels. As infestations are more frequent in warmer seasons (summer and autumn), the research has tested the role of temperature in the efficacy of molluscicides.
