Abstract:
Thirteen steelhead trout (Salmo gairdneri) with coded-wire tags (CWT's)
were captured in gillnets fished by the Oshoro-Maru in the Gulf of Alaska along
145°W in 1980 and 1981 and along 180° in 1981. These fish originated from hatcheries
in Oregon, Washington and Idaho, U.S.A., and British Columbia, Canada. About
7% of all steelhead caught had CWT's One age LO steelhead entered the ocean
about two months before it was captured after migrating at sea at least 1,641 km.
Scales of the steelhead caught in gillnets indicated that most were "wild", non-hatchery
fish, having spent 2 or 3 years in fresh water, and 0, 1 or 2 years
in the ocean.
