Brood stock segregation of spring chinook salmon Oncorhynchus tshawytscha by use of the enzyme-linked immunosorbent assay (ELISA) and the fluorescent antibody technique (FAT) affects the prevalence and levels of Renibacterium salmoninarum in
A study of the effect of maternal Renibacterium salmoninarum infection levels on the prevalence and levels of bacterial kidney disease (BKD) in progeny fish was conducted at a production salmon hatchery. A total of 302 mating pairs of spring chinook salmon Oncorhynchus tshawytscha was screened in August 1988 for R. salmoninarum by an enzyme-linked immunosorbent assay (ELISA). On the basis of ELISA

Polymerase chain reaction (PCR) amplification of a nucleoprotein gene sequence of infectious hematopoietic necrosis virus
The polymerase chain reaction [PCR) was used to amplify a portion of the nucleoprotein [NI gene of infectious hematopoietic necrosis virus (IHNV). Using a published sequence for the Round Butte isolate of IHNV, a pair of PCR pnmers was synthesized that spanned a 252 nucleotide region of the N gene from residue 319 to residue 570 of the open reading frame. This region included a 30 nucleotide targe

Pen rearing and imprinting of fall Chinook salmon. Annual report 1989
The goal of this project is to compare net-pen rearing methods to traditional hatchery methods of rearing upriver bright fall chinook salmon (Oncorhvnchus tshawvtscha). Fish were reared at several densities in net pens at three Columbia River backwater sites during 1984-1987, and in a barrier net at one site during 1984-1986; methods included both fed and unfed treatments. The purpose of this repo

Multiplication of infectious hematopoietic necrosis virus in rainbow trout following immersion infection: whole-body assay and immunohistochemistry
The sites of replication of infectious hematopoietic necrosis virus (IHNV) in infected tissues were detected in fingerling rainbow trout Oncorhynchus mykiss by in situ histologic techniques following immersion infection. Virus antigens in tissues were detected by a neutralizing mouse monoclonal antibody and a one-step anti-mouse biotin-streptavidin conjugated to horseradish peroxidase. The efficie

Feeding ecology of subyearling Chinook salmon in riverine and reservoir habitats of the Columbia River
In the Columbia River, we found the diet of subyearling chinook salmon Oncorhynchus tshawytscha to be predominately caddisflies (Trichoptera; 64% by weight) in riverine nursery habitats, but mostly Daphnia spp. and terrestrial insects in reservoir habitats. A preference analysis indicated that subyearlings did not eat food items in proportion to food availability; they preferred small zooplankters

Use of a fish health condition profile in assessing the health and condition of juvenile Chinook salmon
The fish health condition profile, a simplified system for assessing fish health and condition, was originally developed for fish hatcheries and feral trout populations in Utah. We evaluated the method during routine health assessments of juvenile fall chinook salmon (Oncorhynchus tshawytscha) reared in net pens in the Columbia River in 1986 and 1987. The procedure yielded a thorough assessment of
