Hatchery reared steelhead trout (Salmo gairdneri) released into various streams on Vancouver Island between 1979 and 1983 were adipose fin clipped and coded-wire tagged (CWT). Sport anglers who harvested the returning adult steelhead were encouraged to submit the fish's head to depots located throughout the Island. Between 1982/83 and 1985/86, steelhead anglers harvested a portion (23%) of the hatchery steelhead they caught and voluntarily returned heads from 13% of the fish they killed. A total of 1660 heads were recovered from 17 watersheds on Vancouver Island. The heads represented 0.11% of the total coded-wire tags released. Depending on the stream stocked, each adult CWT recovered represented $40-200 in tagging costs. Significant numbers of marked steelhead were caught in streams other than where they were released as juveniles. For six study watersheds, the straying rate average 9.6% and ranged from 4.3% for streams where incubation and rearing was on-site to 32.7% for smolts outplanted to a receiving ...
