The purpose of this study was to characterize Cytophaga
psychrophila isolates obtained from coho fingerlings with low temperature
disease collected at selected hatcheries in Oregon. In
addition, cultures thought to be related to this bacterium were
isolated from Siletz Hatchery water, deformed juvenile and spawning
adult coho salmon, rainbow and...
A plan for the reestablishment of anadromous salmonid stocks into waters above the Pelton Round Butte Hydroelectric Project (PRB) located on the Deschutes River, Oregon has been under development since 1996. The PRB complex, starting at river kilometer (Rkm) 103, blocks the further upstream migration of anadromous salmonids into upper...
Nearly 3000 juvenile Chinook (Oncorhynchus tshawytscha) and coho (O. kisutch) salmon captured in nearshore waters off the coasts of Washington and Oregon from 1999-2004 were tested for infection by Renibacterium salmoninarum, Nanophyetus salmincola, and skin metacercariae. First, three quantitative PCR primer/probe sets were compared for detection of R. salmoninarum; amplification...
A nested mating experiment in which 20 males were each mated
to four different females was used to obtain an estimate of the heritability
of resistance to death from gas bubble disease in Columbia
River fall chinook salmon (Oncorhynchus tshawytscha). Heritability
estimates ranged from 0. 037 to 0. 038.
