Celebrating America’s 250th anniversary, this Great Lakes Fisheries Heritage trail story explores how fisheries have shaped Michigan and our country throughout history; and how these stories live on today through the people, fish, and fishing that connect our coastline, culture and Great Lakes identity.
Sea lamprey management in the Great Lakes is a tale of crisis, innovation, and resilience.
It is the story of fishing families who endured profound loss yet remained connected in their values and stewardship of the Great Lakes. It is also the story of scientists who pursued solutions through years of careful experimentation. And ultimately a story of an ecosystem that, with sustained effort, began to recover.
Science in action
The discovery of lampricides and the development of integrated pest management represent one of the most significant successes in invasive species control. Few environmental challenges of this scale have seen such measurable, long-term progress.
At the center of that effort stands Vern Applegate. His work at Hammond Bay Biological Station helped redefine what was possible. By combining persistence, scientific rigor, and collaboration, Applegate and his colleagues transformed the trajectory of Great Lakes fisheries.

Read the full story of Vern Applegate’s quest for a solution online.
Today, sea lamprey control remains an ongoing responsibility. The system requires continued monitoring, treatment, and cooperation across jurisdictions. The challenge has not disappeared but it is being met.
Visitors can explore this story across the Great Lakes Fisheries Heritage Trail through historic sites, interpretive centers, and educational exhibits. At Hammond Bay Biological Station itself, the legacy of this work continues, connecting past innovation with present-day stewardship.
The Great Lakes are healthier today because of these efforts. And the lessons learned—about science, persistence, and shared responsibility—remain just as important as the fish that once again swim their waters.
