Complete genome sequence of Fer-de-Lance Virus reveals a novel gene in reptilian Paramyxoviruses Complete genome sequence of Fer-de-Lance Virus reveals a novel gene in reptilian Paramyxoviruses
The complete RNA genome sequence of the archetype reptilian paramyxovirus, Fer-de-Lance virus (FDLV), has been determined. The genome is 15,378 nucleotides in length and consists of seven nonoverlapping genes in the order 3??? N-U-P-M-F-HN-L 5???, coding for the nucleocapsid, unknown, phospho-, matrix, fusion, hemagglutinin-neuraminidase, and large polymerase proteins, respectively. The...

Ichthyophoniasis: An emerging disease of Chinook salmon in the Yukon River Ichthyophoniasis: An emerging disease of Chinook salmon in the Yukon River
Before 1985, Ichthyophonus was unreported among Pacific salmon Oncorhynchus spp. from the Yukon River; now it infects more than 40% of returning adult Chinook salmon O. tshawytscha. Overall infection prevalence reached about 45% in the Yukon River and about 30% in the Tanana River between 1999 and 2003. Mean infection prevalence was greater in females than males in the main-stem Yukon...

High doses of corticosteroid suppress resistance to Ichthyophonus in starry flounder High doses of corticosteroid suppress resistance to Ichthyophonus in starry flounder
Application of pharmacological doses of the corticosteroid dexamethasone phosphate to starry flounder Platichthys stellatus resulted in a predisposition to clinical ichthyophoniasis and a progression from latent Ichthyophonus infections to patent, histologically identifiable infections. Among Ichthyophonus-challenged starry flounder, the prevalences of clinical infections and...

PCB disruption of the hypothalamus-pituitary-interrenal axis involves brain glucocorticoid receptor downregulation in anadromous Arctic charr PCB disruption of the hypothalamus-pituitary-interrenal axis involves brain glucocorticoid receptor downregulation in anadromous Arctic charr
We examined whether brain glucocorticoid receptor (GR) modulation by polychlorinated biphenyls (PCBs) was involved in the abnormal cortisol response to stress seen in anadromous Arctic charr (Salvelinus alpinus). Fish treated with Aroclor 1254 (0, 1, 10, and 100 mg/kg body mass) were maintained for 5 mo without feeding in the winter to mimic their seasonal fasting cycle, whereas a fed...

Distribution and relative abundance of fishes in littoral areas of Chief Joseph Reservoir, Columbia River Distribution and relative abundance of fishes in littoral areas of Chief Joseph Reservoir, Columbia River
We surveyed fish assemblages in littoral areas of Chief Joseph Reservoir of the upper Columbia River to aid in understanding this ecosystem. Fish distributions and abundances were examined during April-July 1999 in relation to environmental conditions in the reservoir. We also compared the fish assemblages in Chief Joseph reservoir in 1999 to a past study conducted during 1974-1975, and...

Epizootiology and histopathology of Parvicapsula sp. in coho salmon Oncorhynchus kisutch Epizootiology and histopathology of Parvicapsula sp. in coho salmon Oncorhynchus kisutch
The epizootiology and histopathology of the myxosporean Parvicapsula sp. was studied during monthly health surveys of 4 groups of coho salmon Oncorhynchus kisutch at a commercial farm in Puget Sound, Washington, USA, from 1984 to 1986. No Parvicapsula sp. was detected in histological samples taken from juvenile fish in fresh water, but the parasite was detected in fish from all groups 2...

Conditions for growth and survival of bull trout in Beulah Reservoir, Oregon. Annual report 2002 Conditions for growth and survival of bull trout in Beulah Reservoir, Oregon. Annual report 2002
The Bureau of Reclamation (BOR) constructed Agency Valley Dam on the North Fork of the Malheur River in 1934-35, creating Beulah Reservoir. The project is operated and maintained by the Vale Irrigation District for irrigation and downstream flood control. There is currently no formal agreement for a minimum pool level at Beulah Reservoir, but project operators of Agency Valley Dam and...
