United States Sen. Carl Levin, D-Mich., eyes some adult sea lampreys at the U.S. Geological Survey Hammond Bay Biological Station as Chris Goddard, Great Lakes Fishery Commission executive secretary, explains how to battle the parasite. Jill Wingfield, the commission’s senior communications associate, watches from the left of Goddard. Station staff, who work for multiple agencies, are researching various ways to trap and kill the blood-sucking vertebrate. Research ecologist Nick Johnson explained how synthetic phermones can be used to attract male lampreys into traps, and demonstrated repellant substances as well. It’s all part of an effort to disrupt the invasive species’ reproductive cycle, reducing their numbers and saving Great Lakes fisheries in the process. Levin also learned about other research done at the station, including a project that tracks the movement of fish through the lakes. Goddard and Leon Carl, USGS Midwest Area regional executive, thanked Levin for his support in the Senate of the efforts of the USGS and other agencies involved in the research.
