Lake Champlain's Wild Lake Trout Rebound

Fisheries managers are beginning to see positive signs of a self-sustaining wild lake trout population. Since hatchery fish are marked by a fin clip before being stocked in the lake, a rising tide of unclipped trout indicates an improving wild population. Researchers track the rate of wild fish caught in gillnets left in the lake for 24 hours as a measure of population health.
