Abstract
Using acoustic telemetry data and acceleration sensors, the authors compared the metabolic costs of lake trout between four populations in lakes with varying types of prey. They determined that lake trout feeding behaviour was characterized by clearly delineated periods of active hunting and rest. Populations with prey that were smaller or more difficult to catch had fewer resting periods and expended more energy during active periods.
