The battle against lampreys moves to two more locations today.
U.S. Fish and Wildlife Service crews will assess the Trap Rock River and Hungarian Creek.
Young lamprey live in the sand and silt at the bottom of Great Lakes tributaries for several years between the time they hatch, and the time they are mature enough to swim out, and begin preying on fish.
Electrofishing will be used to induce them out of hiding in shallow areas. Deeper waters will be treated with an approved lampricide (Bayluscide 3.2% Granular Sea Lamprey Larvicide) in selected areas to help determine the population.
The results of the survey will help construct a plan to treat the entire streams, if necessary. Work should be completed by late next week.
