Radio tags are used by the
Idaho Fishery Resource Office (located at Dworshak National Fish Hatchery)
to study the movements of salmon and steelhead.
One ongoing study being conducted
by Idaho FRO 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
