      Feds to treat Emmet County waters for sea lamprey

      A sea lamprey attacking a trout. Sea lamprey are an invasive species in the Great Lakes that nearly destroyed all of the lake trout.

      The U.S. Fish and Wildlife Service plans to treat four Emmet County waterways to control invasive sea lamprey.

      The treatments are expected to take place between Sept. 24 and Oct. 3 in Big Stone Creek, Big Sucker Creek, the Wycamp Lake outlet and the Carp Lake outlet.

      They'll use a special poison designed to kill lamprey but not other fish.

      Fish biologist Alex Gonzalez says streams usually are treated on a four-year cycle. But the Emmet County waters are being treated in two successive years.

      He says it's part of an experiment to see if repeated treatments will knock down lamprey numbers.

      Sea lamprey are eel-like parasites that entered the Great Lakes through shipping canals in the early 1900s and decimated native lake trout.
