UNDATED (KDAL) – In an effort to kill sea lamprey larvae before they grow up and migrate into Lake Superior, the U-S Fish and Wildlife Service is applying “lampricides” to the Bad River in Ashland and Bayfield Counties.
The application of the lampricide, through October 3rd, poses no unreasonable threat to the general population of the river but is selectively toxic to lampreys.
As with any pesticide, the public is advised to use discretion and minimize unnecessary exposure.
Failure to kill sea lamprey larvae in streams would result in significant damage to the Great Lake fishery.
Infested tributaries are treated every three to five years to control the lamprey population.
The program to chemically control sea lampreys began in 1958 by the Great Lakes Fisheries Commission to maintain sport and commercial fisheries.
