Foreign mussels hitchhiking to the Great Lakes in the ballast water tanks of international freighters are becoming one of the most vexing environmental problems facing the Great Lakes. A group of scientists from Wayne State University, in collaboration with the United States Geological Survey and the Environmental Protection Agency, are working together to battle this problem.
Researchers at Grand Valley State University’s Annis Water Resources Institute are finding that harmful algae blooms in two West Michigan lakes are linked to the water-clarifying action of the invasive species zebra mussels.
Despite opposition from environmentalists, the U.S. House is moving ahead with legislation proposing a national standard for cleansing ballast water from foreign ships.
The ongoing spread of non-native mussels in the Great Lakes has caused “massive, ecosystem-wide changes” throughout lakes Michigan and Huron, two of the planet’s largest freshwater lakes, according to a new University of Michigan-led study.
