Numerous research projects have been conducted on sheefish throughout the state of Alaska. The Alaska Department of Fish and Game, US Fish and Wildlife Service, and University of Alaska have all studied sheefish in recent years. This research has improved understanding of sheefish life history. Many of these projects use radio telemetry (biologists place radio transmitter tags into fish and then follow the signal in order to track the fish‘s movements). The information gathered is used to better manage and protect sheefish stocks and habitat.
