Fish Tracking Radio Tags

Radio tags are used by the Idaho Fish and Wildlife Conservation Office (located at Dworshak National Fish Hatchery) to study the movements of salmon and steelhead.

One ongoing study being conducted by Idaho FWCO biologists involves radio-tagging adult steelhead to determine their spawning distribution. The target fish are unclipped hatchery fish released as juveniles in tributaries of the South Fork Clearwater River in hopes they will return to their release location and spawn. By unclipped, we mean their adipose fin is intact and thus the fish cannot be legally harvested. In addition to releasing the fish unharmed, we would prefer that anglers do not pull radio tags from unclipped hatchery steelhead so that we can track the fish to their spawning location. The University of Idaho has long been radio-tagging salmon and steelhead in the Snake River basin. Their studies benefit from having fish captured and radio tags returned, and to promote the collection of radio tags they offer cash awards for tag returns. We do not offer any monetary awards because having the radio tags removed from our study fish reduces our chances of determining spawning distribution. However, if you did remove the radio tag there is no penalty and we would greatly appreciate the information on the tag, as well as when and where you caught the fish.
