Relative resistance of Pacific salmon to infectious salmon anaemia virus Relative resistance of Pacific salmon to infectious salmon anaemia virus
Infectious salmon anaemia (ISA) is a major disease of Atlantic salmon, Salmo salar, caused by an orthomyxovirus (ISAV). Increases in global aqua culture and the international movement of fish made it important to determine if Pacific salmon are at risk. Steelhead trout, Oncorhynchus mykiss, and chum, O. keta, Chinook, O. tshawytscha, coho, O. kisutch, and Atlantic salmon were injected

Migration of precocious male hatchery chinook salmon in the Umatilla River, Oregon Migration of precocious male hatchery chinook salmon in the Umatilla River, Oregon
Between 1993 and 2000, precocious yearling males of hatchery-produced fall and spring chinook salmon Oncorhynchus tshawytscha composed 3.6-82.1% of chinook salmon runs to the Umatilla River, Oregon. These yearling males are smaller than typical jack salmon, which spend a full winter in the ocean, and are commonly referred to as "mini jacks." Minijack fall chinook salmon are characterized...

Differences in native soil ecology associated with invasion of the exotic annual chenopod, Halgeton glomeratus Differences in native soil ecology associated with invasion of the exotic annual chenopod, Halgeton glomeratus
Various biotic and abiotic components of soil ecology differed significantly across an area whereHalogeton glomeratus is invading a native winterfat, [ Krascheninnikovia (= Ceratoides) lanata] community. Nutrient levels were significantly different among the native, ecotone, and exotic-derived soils. NO3, P, K, and Na all increased as the cover of halogeton increased. Only Ca was highest...

Lateral line pore diameters correlate with the development of gas bubble trauma signs in several Columbia River fishes Lateral line pore diameters correlate with the development of gas bubble trauma signs in several Columbia River fishes
Gas bubble trauma (GBT) caused by gas supersaturation of river water continues to be a problem in the Columbia River Basin. A common indicator of GBT is the percent of the lateral line occluded with gas bubbles; however, this effect has never been examined in relation to lateral line morphology. The effects of 115, 125 and 130% total dissolved gas levels were evaluated on five fish...

Host and geographic range extensions of the North American strain of viral hemorrhagic septicemia virus Host and geographic range extensions of the North American strain of viral hemorrhagic septicemia virus
Viral hemorrhagic septicemia virus (VHSV) was isolated from populations of Pacific sardine Sardinops sagaxfrom the coastal waters of Vancouver Island, British Columbia, Canada, and central and southern California, USA. The virus was also isolated from Pacific mackerel Scomber japonicus in southern California, from eulachon or smeltThaleichthys pacificus, and surf smelt Hypomesus...

Thermal exposure of juvenile fall chinook salmon migrating through a lower Snake River Reservoir Thermal exposure of juvenile fall chinook salmon migrating through a lower Snake River Reservoir
Impoundment of the Snake River, Washington, has resulted in high water temperatures and late seaward migration of juvenile fall chinook salmon during summer months. To determine if juvenile fall chinook salmon are exposed to temperatures higher than the upper incipient lethal, we tagged groups of fish with temperature-sensing radio tags and tracked them in Little Goose Reservoir on the...
