EVALUATING THE RISKS AND POTENTIAL OF GENETIC TECHNOLOGIES FOR MANAGING THE IMPACTS OF SEA LAMPREYS IN THE GREAT LAKES

Currently the GLFC manages the impacts of sea lampreys through a combination of trapping, barriers, and lampricides. Over the next several years, the GLFC faces potentially elevated control costs due to pressure to remove barriers that currently prevent sea lamprey access to large areas of productive habitat, in the absence of alternative long-term, cost-effective options. Modern genetic technology could provide such an option. Over the last decade, such technology has progressed to the point of functional “daughterless” constructs in fish, successful field trials of similar approaches for controlling disease-vectoring insects and preliminary models of GL lamprey population dynamics that indicate the parasite may be particularly susceptible to genetic technology. Given these developments and continuing challenges with lampricides, it may be timely for the GLFC to re-examine the possibility of using genetic tools to manage lampreys in the GL. We will provide an expert review of the technical feasibility and cost of development of the approach in lampreys, the risks involved in its deployment, and the likelihood that it will suppress lamprey impacts, with the goal of informing future GLFC decision-making.
