Sea Lamprey Treatment Taking Place in May

Posted on Behalf of Great Lakes Fishery Commission and U.S. Fish and Wildlife Service

From May 9-18 the U.S. Fish and Wildlife Service in partnership with the Great Lakes Fishery Commission will deliver sea lamprey control on three Tittabawassee River tributaries: Tobacco River, Little Molasses River and Black Creek. Sea lampreys are parasitic fish invasive to the Great Lakes. The lampricide stream treatments, using TFM, will target larval lampreys. Lampricides do not pose a risk to human health or to the environment. They do not remain after application and naturally break down in the environment.

Information Session

On Monday, April 17th from 5-7 pm, the Great Lakes Fishery Commission will host an information session at the Beaverton Activity Center (106 Tonkin Street, Beaverton, MI 48612) to explain the lampricide application process and answer questions.
