Characterizing the Juvenile Fish Community in Turbid Alaskan Rivers to Assess Potential Interactions with Hydrokinetic Devices
Abstract Installation of hydrokinetic power‐generating devices is currently being considered for the Yukon and Tanana rivers, two large and glacially turbid rivers in Alaska. We sampled downstream‐migrating fish along the margins of both rivers, a middle island in the Yukon River, and mid‐channel in...
