Battling Sea Lamprey Using Cutting Edge Technology

Annually, from March through October, the Marquette and Ludington Biological Stations control and assess the presence, distribution and abundance of sea lamprey in the Great Lakes and its tributaries. This year was especially exciting in the battle against this vampire-like invasive species. Sea lamprey Abundance numbers are at their lowest levels in decades in Lake Huron and Michigan according to data released by the Great Lakes Fishery Commission.

The Sea Lamprey Control Program stays on the cutting edge of technology to increase the number of tools available- allowing for more effective work. Research this year included studying how sea lamprey pheromones and alarm cues influence the invader's migration behavior, as well as improving the efficiency of trapping technology via eel ladders and directed water currents to guide sea lamprey into traps. The Service's sea lamprey pest management program has been and continues to be successful because of adaptive management and applying innovative solutions to an ever changing environment.
