A groundbreaking study found that invasive zebra mussels significantly alter aquatic ecosystems, and are associated with elevated mercury concentrations in fish. Mercury, a potent neurotoxin, poses a serious threat to both aquatic life and human health.
Recently published in Science of the Total Environment, a team of researchers at the University of Minnesota College of Food, Agricultural and Natural Resource Sciences, Minnesota Aquatic Invasive Species Research Center, and the U.S. Geological Survey studied 21 Minnesota walleye lakes to assess the impact of zebra mussels on food webs and fish tissue mercury concentrations.
