---- — TRAVERSE CITY — Scientists plan to find and kill parasitic fish in several local waterways.
The U.S. Fish and Wildlife Service is conducting two surveys for sea lamprey in the Boardman River, Leland River and Cedar Creek from June 17 to June 21. Crews also will apply chemicals used to poison and kill larval sea lamprey in the Betsie River during the same time period.
Sea lamprey travel from Lake Michigan to spawn in tributaries feeding into the lake. The surveys determine the number of lamprey in the streams in order to see which need to be treated before the larvae grow up into parasitic adults feeding on native fish in the Great Lakes.
