A look at the Innoko Sheefish Project: fishery biologists are studying sheefish in Interior Alaska. An overview of the project, the importance of the fish to the subsistence lifestyle of the people of the village of Shageluk. Biologists capture and implant radio telemetry tags in sheefish in the Innoko to learn more about their movements, spawning areas and feeding areas in the Yukon River drainage. The tags can potentially last seven years. About 20 minutes. Produced in 2009 as a coproduction of ADF&G, USFWS and BLM.
