Spiral swimming behavior due to cranial and vertebral lesions associated with Cytophaga psychrophila infections in salmonid fishes Spiral swimming behavior due to cranial and vertebral lesions associated with Cytophaga psychrophila infections in salmonid fishes
C. psychrophila infections of the cranium and anterior vertebrae in salmonid fishes were associated with ataxia, spiral swimming along the axis of the fish, and death. The syndrome was observed in 2-10% of underyearling coho salmon Oncorhynchus kisutch, rainbow troutSalmo gairdneri, and steelhead trout S. gairdneri at several private, state, and federal hatcheries in Washington and...

Biochemical and antigenic properties of the first isolates of infectious hematopoietic necrosis virus from salmonid fish in Europe Biochemical and antigenic properties of the first isolates of infectious hematopoietic necrosis virus from salmonid fish in Europe
The first isolates of infectious hematopoietic necrosis virus (IHNV) recovered from rainbow trout Oncorhynchus mykiss (formerly Salmo gairdneri) in France and Italy were compared to six representative strains from North America by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of virion polypeptides and neutralization by monoclonal antibodies (MAbs). All three IHNV...

Variation in capture efficiency of a beach seine for small fishes Variation in capture efficiency of a beach seine for small fishes
We determined the capture efficiency of a beach seine as a means of improving abundance estimates of small fishes in littoral areas. Capture efficiency for 14 taxa (individual species or species groups) was determined by seining within an enclosure at night over fine and coarse substrates in the John Day Reservoir, Oregon–Washington. Mean efficiency ranged from 12% for prickly sculpin...

Construction and emplacement of a large enclosure for rearing fish off-station Construction and emplacement of a large enclosure for rearing fish off-station
A 1.5-acre barrier net, used to enclose large numbers of juvenile Pacific salmon (Oncorhynchus spp.) for rearing in backwaters along the Columbia River, USA, is described. This type of enclosure may provide additional rearing options to fishery managers.

Concentration of infectious hematopoietic necrosis virus from water samples by tangential flow filtration and polyethylene glycol precipitation Concentration of infectious hematopoietic necrosis virus from water samples by tangential flow filtration and polyethylene glycol precipitation
Infectious hematopoietic necrosis virus (IHNV) was concentrated from water samples by polyethylene glycol (PEG) precipitation, tangential flow filtration (TFF), and by a combination of TFF followed by PEG precipitation of the retentate. Used alone, PEG increased virus titers more than 200-fold, and the efficiency of recovery was as great as 100%. Used alone, TFF concentrated IHNV more...

A method to directly measure maximum volume of fish stomachs or digestive tracts A method to directly measure maximum volume of fish stomachs or digestive tracts
A new method for measuring maximum stomach or digestive tract volume of fish incorporates air injection at constant pressure with water displacement to measure directly the internal volume of a stomach or analogous structure. The method was tested with coho salmon, Oncorhynchus kisutch (Walbaum), which has a true stomach, and northern squawfish, Ptychocheilus oregonensis(Richardson)...

Developments in the control of bacterial kidney disease of salmonid fishes Developments in the control of bacterial kidney disease of salmonid fishes
Bacterial kidney disease of salmonid fishes, caused by Renibactenum salrnoninarum, was first reported more than 50 yr ago; nevertheless, large gaps persist in our knowledge of the infection - particularly in methods for its control. In the 1950's, principal control measures consisted of prophylactic or therapeutic feeding of sulfonamides, which were later supplanted by the antibiotic...

Response of salmonid fish to artificial infection with chum salmon virus Response of salmonid fish to artificial infection with chum salmon virus
In the fall of 1978, a reovirus was isolated from normal-appearing adult chum salmon (Oncorhynchus keta) returning to the Tokushibetsu Hatchery in Hokkaido, Japan (Winton et al 1981). The chum salmon virus (CSW) was recovered in the chinook salmon (Oncorhynchus tshawytscha) embryo cell line (CHSE-214) where it replicated at 15-20 C, producing foci of syncytia in the monolayer. Electron...
