Studying the Invasive Sea Lamprey in the Jordan River

Sea lamprey control research was the topic of a special presentation held
at the Friends of the Jordan board meeting on July 17, 2014.

Michigan State University scientists, in cooperation with the Great Lakes Fisheries Commission, are developing new treatment strategies which were being tested in some Jordan River tributaries this summer. The technique, called “push-pull trapping” involves the use of negative scents to deter the lampreys from certain streams and positive pheromones to attract them to others. The goal is to reduce the amount of trifluoromethyl nitrophenol piscicide [TFM] currently needed to control the invasive lamprey.

Dr. Tom Luhring is a post-doctoral researcher at Michigan State University with the Wagner Lab,
which studies behavior and ecology of native and invasive fishes.
