“Thousands of sea lamprey are passed upstream [on the Connecticut River] each year. This is a predator that wiped out the Great Lakes lake-trout fishery. [Lampreys] literally suck the life out of their host fish, namely small-scale fish such as trout and salmon. The fish ladders ought to be used to diminish the lamprey.” So editorialized the Lawrence (Massachusetts) Eagle-Tribune on December 15, 2002. If that’s true, why this spring is Trout Unlimited — the nation’s leading advocate for trout and salmon — assisting the Town of Wilton, Connecticut and an environmental group called “Save the [Long Island] Sound” in a project that will restore 10 miles of sea lamprey spawning habitat on the Norwalk River? Why this summer will the first big returns from stocked Pacific lampreys — a species similar to sea lampreys — climb specially-designed lamprey ramps at Columbia River dams and surge into historical spawning habitat in Oregon, Washington, and Idaho?
