Abstract
Experience gained in the successful program to control sea lamprey (Petromyzon marinus, an invasive, exotic species in the Great Lakes) may provide insights into philosophies and methods for control of ruffe (Gymnocephalus cernuus). The Great Lakes Fishery Commission (GLFC) mandates an integrated pest management program approach to sea lamprey control. Key features of an integrated pest management program are (1) assessment of populations and projection of damage so that treatment intensity does not exceed the level where costs balance the injury avoided, and (2) the integrated use of a suite of alternative control techniques to minimize the reliance on and potential negative effects of single methods. The sea lamprey control program still depends largely on removal of sea lamprey during their larval stage with the lampricide TFM, either alone or together with Bayer-73. Although low-head barriers and traps are currently the only operational alternative to lampricides, the large-scale release of sterilized male sea lamprey is also being tested on an experimental basis. The policy of the GLFC, however, is to continue to research and develop other effective alternative methods. Based on information gathered during the continuing search for alternatives, we will summarize pest control technologies, including ones that have been used operationally, investigated, or simply hypothesized. The objective of this presentation is to provide an overview of pest control methods to help other participants focus on knowledge and lines of inquiry within their disciplines that might lead to methods for control of ruffe.
