Marquette Biological Station

Marquette Biological Station was established in 1956 to support sea lamprey research, monitoring and control efforts. We work with state, tribal and other federal agencies to monitor progress towards fish community objectives for sea lampreys in each of the Great Lakes, but also to develop and implement actions to achieve these objectives.

Our Species

The work of the Marquette Biological Station focuses on sea lamprey control. Sea lampreys are native to the Atlantic Ocean. In the 1800s, sea lampreys entered into the Great Lakes system via manmade locks and shipping canals. Sea lampreys were first observed in Lake Ontario in the 1830s. Niagara Falls served as a natural barrier preventing sea lampreys from entering the other Great Lakes, but modifications to the Welland Canal in the early 1900s provided sea lampreys a path to invade the other lakes. In 1921 sea lampreys were first observed in Lake Erie and quickly spread into Lakes Michigan, Huron and Superior.

Visit Us

Marquette Biological Station is not traditionally open for public visits or tours but may offer tours and information about sea lamprey research and management in the Great Lakes. We request that you call ahead to set up an appointment with our staff. This will ensure that our staff are prepared to visit with you and your group.
