The Oregon strain of the agent of infectious hematopoietic necrosis (IHN) was isolated from fingerling sockeye salmon (Oncorhynchus nerka) by J. L. Fryer in 1958. Before the study reported herein no other virus had been recovered from any fish population in Oregon. Therefore, in July, 1971 a survey was initiated...

The occurrence and distribution of fish viruses in Oregon were
determined by the examination of anadromous and fresh water salmonids.
Infectious pancreatic necrosis virus (IPNV) was isolated and
identified from asymptomatic adult coho (Oncorhynchus kisutch) and
chinook (0. tshawytscha) salmon returning to the Columbia River
system. Infectious pancreatic necrosis virus...
The distribution in Oregon of two viruses affecting salmonid
fishes was determined by examination of hatchery and feral fish.
Infectious pancreatic necrosis virus (IPNV) was isolated from fish
at the Oregon Department of Fish and Wildlife Research Laboratory,
Corvallis, Roaring River, Fort Klamath, and Wizard Falls Hatcheries.
Fish collected at...
Juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout
(Salmo gairdneri) of different stocks and three transferrin genotypes
(AA, AC, and CC), all reared in identical or similar environments, were
experimentally infected with the causative agent of bacterial kidney
disease (BKD) or Vibrio anguillarum. Mortality due to the pathogens
was compared...
The pulmonary function scores of 250 male cigarette smokers
were compared with 406 lifetime nonsmokers. A Stead-Wells spirometer
was used to obtain forced vital capacity, forced expiratory
flow, forced mid-expiratory flow, and forced expiratory volume. All
individuals included in the sample were between. the ages of 20 and
49 years....
Six salmonid cell lines previously established in this laboratory,
CHSE 114 and CHSE 214 (chinook salmon), CSE 119 (coho salmon),
SSE 5 (sockeye salmon), STE 137 (steelhead trout) and RTH 149 (rainbow
trout), were partially characterized. Mycoplasmas were not
detected in any of the cell lines.
All cell lines exhibited...

The problem of estimating the parameters of a forced discrete
linear dynamic model is considered. The system model is conceptualized
to include the value of the initial state as a parameter. The forces
driving the system are partitioned into accessible and inaccessible
inputs. Accessible inputs are those that are measured;...
This study involved the use of the two-choice preference test to determine the taste reactions of buck and doe Columbian black-tailed deer (Odocoileus hemionus columbianus) to ascending concentrations of water extracts of Douglas fir, red alder, cascara, western hemlock and bitterbrush; to an ethanol extract of Douglas fir, and to...
