100 years of sea lampreys above Niagara Falls: A reflection on what happened and what we learned

Abstract In the one hundred years since sea lampreys (Petromyzon marinus) were discovered in Lake Erie, the species completed its invasion throughout the Great Lakes basin, contributed to the downfall of the commercial fishing industry, and served as a catalyst for the development of the collaborative fishery management regime that exists today. The sea lamprey invasion simultaneously caused wide-spread devastation while giving rise to a collective realization that the health of the Great Lakes would require ongoing cooperation among governments, scientists, and users of the resource. Since its inception, the effort to control sea lampreys in the Great Lakes has been defined by a “shoot for the moon” mentality. The desperation of communities directly harmed by the sea lamprey invasion, coupled with the determination and unyielding commitment to science by those tasked with addressing the problem, led to the formation of the only reported successful aquatic vertebrate invasive species control program at an ecosystem scale.
