Where are Sea Lampreys Controlled

The Great Lakes Fishery Commission works with Fisheries and Oceans Canada, the U.S. Fish and Wildlife Service, and the U.S. Army Corps of Engineers to undertake sea lamprey control. The control program uses several techniques to attack sea lampreys. This effort (known as "integrated sea lamprey management") includes:

• sea lamprey assessment
• lampricide control
• sea lamprey barriers
• sea lamprey traps
• the sterile-male-release-technique

Sterile-male-release-technique

The sterile-male-release-technique is used entirely on the St. Marys River, the connecting channel between Lakes Superior and Huron. Most sterilized male sea lampreys (which are past their parasitic phase and, therefore, do not prey on fish) are released near Sugar Island in Michigan and at Bellevue Park in Canada.
