Studies of the freshwater ethology of the wild winter steelhead trout (Salmo gairdneri) were conducted by the Ministry of Environment during the 1982-83 season on Gold River, a major steelhead river in northwestern Vancouver Island. Radio telemetry was employed to monitor in-stream movements and to determine the timing and location of spawning. From December 1982 to April 1983, 219 steelhead were angled a short distance upstream from tidal waters; of these, 32 recent immigrants (14.6%) were tagged with internal radio transmitters, and movements were monitored approximately weekly. Twenty-four of 32 radio-tagged steelhead (75%) were tracked through spawning and emigration. Eight radio tags either malfunctioned, were lost to predation, or were regurgitated. Of 219 tagged steelhead, 27 (12.3%) were reported recaptured by anglers. Recaptures were highest among steelhead tagged in December and January. Few February tags and no March-April tags were recovered. Anchor tagged steelhead controls were recaptured nearly
