Assessment of smolt condition for travel time analysis. Annual report 1989 Assessment of smolt condition for travel time analysis. Annual report 1989
The Water Budget is a volume of water used to enhance environmental conditions (flows) in the Columbia and Snake rivers for juvenile salmonids during their seaward migration. To manage the Water Budget, the Fish Passage Center estimates travel times of juvenile salmonids in index reaches of the main-stem rivers, using information on river flows and the migrational characteristics of the...

Management implications of a model of predation by a resident fish on juvenile salmonids migrating through a Columbia River reservoir Management implications of a model of predation by a resident fish on juvenile salmonids migrating through a Columbia River reservoir
We constructed a model ofpredation by northern squawfish Ptychocheilus oregonensis on juvenile salmonids migrating through John Day Reservoir. The model predicts salmonid survival as a function of number and distribution of northern squawfish, number and timing of juvenile salmonids entering the reservoir, salmonid residence time, water temperature, and flow. The model predicted survival...

Multiplication of infectious hematopoietic necrosis virus in rainbow trout following immersion infection: whole-body assay and immunohistochemistry 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...

Feeding ecology of subyearling Chinook salmon in riverine and reservoir habitats of the Columbia River 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...

Use of a fish health condition profile in assessing the health and condition of juvenile Chinook salmon 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...

Isolation of infectious hematopoietic necrosis virus from a leech (Piscicola salmositica) and a copepod (Salmincola sp.), ectoparasites of sockeye salmon Oncorhynchus nerka Isolation of infectious hematopoietic necrosis virus from a leech (Piscicola salmositica) and a copepod (Salmincola sp.), ectoparasites of sockeye salmon Oncorhynchus nerka
Infectious haematopoietic necrosis (IHN) virus was isolated from freshwater leeches Piscicola salmositica and copepods Salmincola sp. removed from the gills of spawning sockeye salmon, Oncorhynchus nerka. This is the first report of the isolation of IHN virus from an animal other than salmonid fishes. High levels of IHN virus were also found in leeches taken from the bottom gravel of the...
