Sea lamprey population dynamics: updating demographic models andapplication to a novel control strategy

Since the early 198 s, population models have been used to explore the efficacy and weaknesses of possible strategies for managing sea lampreys.  The early models played a critical role in providing the conceptual basis for IMSL, but suffered from very limited information on sea lamprey demographics.  Since the mid-199 s the situation has improved markedly, however, largely as the result of assessment and research programs that have yielded large amounts of data on sea lamprey growth, metamorphosis, and recruitment. These new data have created an opportunity to update and greatly refine the models, and then use them to evaluate the potential of existing and novel control strategies. We propose to assemble and analyze the recent data, develop updated life-cycle population models for sea lamprey, and use the new models to assess integrated strategies that involve use of existing control methods, as well as a novel method based on genetic manipulation to distort sex ratios of Great Lakes lamprey populations.
