Great Lakes Sea Lampreys: From Crisis to Control

Presented by: Ross Shaw, Senior Program Associate, Great Lakes Fishery Commission

Sea lampreys are one of the most destructive invasive species to ever enter the Great Lakes. Upon their invasion in the mid-1900s, sea lampreys destroyed the Great Lakes fisheries and the economy that relied upon them. In response to the cries for help from citizens across the basin, the governments of Canada and the United States came together to form the Great Lakes Fishery Commission via a treaty in 1955. For more than 60 years, the Commission has facilitated a binational sea lamprey control program to great success. Sea lamprey populations have been reduced by more than 90%, making the control program one of the most successful aquatic invasive species control programs in the world. Come learn about the history of the Commission, the techniques used to successfully control sea lampreys, and what lies ahead for the sea lamprey control program.
