Anglers, others urged to not disturb spawning sea lamprey
SPRINGFIELD, Vt. (AP) — The Vermont Fish & Wildlife Department is urging anglers and others not to disturb spawning sea lamprey in the Connecticut River and some of its tributaries.
They are not to be confused with a separate population of sea lamprey that are controlled as a nuisance species in Lake Champlain.
The department says sea lamprey spawn each spring in the main stem of the Connecticut River and in many tributaries.
Officials say adult sea lamprey die shortly after returning to freshwater to spawn.
The department says the larval lamprey live in freshwater for a few years burrowed in sandy substrate. At age 5, they move downstream to the ocean where they feed on fish as parasites.
