Sea Grant funds sea lamprey research on Lake Superior

Feb 28 2010

Despite 70 years of control efforts, a University of Wisconsin researcher said climate change and a warming Lake Superior could lead to a rise of the invasive — and destructive — sea lamprey.

Methods ranging from chemicals to barriers have been tried to control sea lampreys, which have a round mouth full of teeth and attach to fish, draining their blood until they drop dead to the bottom. Those who study sea lamprey readily admit complete eradication throughout the Great Lakes is all but impossible.
