Sea lamprey control planned

MANISTIQUE – U.S. Fish and Wildlife Service personnel will apply lampricides to two major tributaries of the Manistique River to kill sea lamprey larvae burrowed in the stream bottom. These tributaries include the Fox and Driggs rivers in Schoolcraft County.

Applications will be conducted on or around Aug. 28 until Sept. 6, in accordance with State of Michigan permits. Application will be complete in approximately six days. Application dates are tentative and may be changed based upon local weather or stream conditions near the time of treatment.

Sea lamprey larvae live in certain Great Lakes tributaries and transform to parasitic adults that migrate to the Great Lakes and kill fish. Failure to kill the larvae in streams would result in significant damage to the Great Lakes fishery. Infested tributaries must be treated every three to five years with lampricides to control sea lamprey populations.

The U. S. Environmental Protection Agency and Health Canada Pest Management Regulatory Agency have reviewed human health and environmental safety data for lampricides and in 2003 concluded that the lampricides (Lampricid and Bayluscide) pose no unreasonable risk to the general population and the environment when applied at concentrations necessary to control larval sea lampreys. However, as with any pesticide, the public is advised to use discretion and minimize unnecessary exposure.
