Optimization of nested polymerase chain reaction assays for identification of Aeromonas salmonicida, Yersinia ruckeri and Flavobacterium psychrophilum Optimization of nested polymerase chain reaction assays for identification of Aeromonas salmonicida, Yersinia ruckeri and Flavobacterium psychrophilum
Nested polymerase chain reaction (PCR) assays were developed using first-round primers complementary to highly conserved regions within the bacterial 16S ribosomal RNA (rRNA) gene (universal eubacterial primers) and second-round primers specific for sequences within the 16S rRNA genes of Aeromonas salmonicida, Yersinia ruckeri, andFlavobacterium psychrophilum. Following optimization of...

Incidence of Ichthyophonus hoferi in Puget Sound fishes and its increase with age of Pacific herring Incidence of Ichthyophonus hoferi in Puget Sound fishes and its increase with age of Pacific herring
A recent decrease in the mean age of adult Pacific herring Clupea pallasi in Puget Sound was associated with a high prevalence of Ichthyophonus hoferi, a protistan parasite that can be highly pathogenic to Pacific herring. In Puget Sound, high intensities of I. hoferiinfection may be maintained in older cohorts of Pacific herring because the prevalence ofI. hoferi increased with age from...

Biography of Dr. John L. Fryer Biography of Dr. John L. Fryer
There is probably no one in the fish health community who does not recognize the name of Professor John L. Fryer. Active in research for a period of more than 40 years, Dr Fryer has achieved international acclaim for his work on infectious diseases of Pacific salmon. The research from his laboratory at Oregon State University (OSU) has spanned the disciplines of virology, parasitology...

Spatial organization of desert tortoises and their burrows at a landscape scale Spatial organization of desert tortoises and their burrows at a landscape scale
We thoroughly surveyed two 9 km 2 study plots using 624 km of transect lines in the south- central Mojave Desert, California, mapping with a precision global positioning system the location of desert tortoises (Gopherus agassizii) and their burrows. We found 98 desert tortoises and 1463 tortoise burrows. Three separate geospatial methods (quadrat-variance, nearest neighbor, and 3...

Antibody-producting cells correlated with body weight in juvenile Chinook salmon Oncorhynchus tshawytscha acclimated to optimal and elevated temperatures Antibody-producting cells correlated with body weight in juvenile Chinook salmon Oncorhynchus tshawytscha acclimated to optimal and elevated temperatures
The immune response of juvenile chinook salmon (Oncorhynchus tshawytscha) ranging in weight from approximately 10 to 55 g was compared when the fish were acclimated to either 13 or 21° C. A haemolytic plaque assay was conducted to determine differences in the number of antibody-producing cells (APC) among fish of a similar age but different body weights. Regression analyses revealed...

Predation by northern pikeminnow on juvenile salmonids in The Dalles Dam tailrace: field, laboratory, and habitat modeling studies (FY2000) Predation by northern pikeminnow on juvenile salmonids in The Dalles Dam tailrace: field, laboratory, and habitat modeling studies (FY2000)
Predation by resident fish is known to be a substantial cause of juvenile salmonid mortality, especially in dam tailraces and outfall locations. Conditions in The Dalles Dam tailrace are unique compared to other projects on the Columbia or Snake rivers, having a complex basin with a series of downriver islands where predators are known to reside. In May-June of 1999, northern pikeminnow...
