Theme overview
The Great Lakes Fishery Commission relies on two registered lampricides, 3-trifluoromethyl-4-nitrophenol (TFM) and niclosamide to control sea lamprey populations in the Great Lakes. Despite the highly successful use of these lampricides, the Great Lakes Fishery Commission and its partners continue to work together to investigate how to improve lampricide efficacy and safety. Current research on TFM and niclosamide is focused on improving treatment effectiveness, predicting and minimizing the effects of lampricides on non-target organisms, understanding the modes of toxic action of TFM and niclosamide, developing next generation lampricides, and ascertaining the environmental fate of lampricides. Emerging research ideas include assessing the possibility of lampricide resistance in sea lamprey and strategies to develop novel lampricides that are more environmentally benign. Use of novel technologies in genomics and green chemistry are also emerging as key research directions in the search for more effective means to control invasive sea lamprey in the Great Lakes.
