Retention of mercury by salmon Retention of mercury by salmon
Consuming fish that have been exposed repeatedly to mercury derivatives is a potential public health hazard because fish can accumulate and retain mercury in their tissues (Rucker, 1968). Concern has been expressed in the United States because mercurials have been used extensively in industry and as prophylactic and therapeutic agents in fish hatcheries. Rucker and Amend (1969) showed...

Control of infectious Hematopoietic Necrosis virus disease by elevating the water temperature Control of infectious Hematopoietic Necrosis virus disease by elevating the water temperature
Studies were performed to determine if increasing water temperatures could control infectious hematopoietic necrosis virus (IHN) disease in sockeye salmon (Oncorhynchus nerka). Mortalities could be prevented if the water temperature was raised to at least 18 C within the first 24 hr after infection of the fish and if the fish were maintained at this temperature for 4–6 days. The disease...

Morphology of certain viruses of Salmonid Fishes. I. in vitro studies of some viruses causing Hematopoietic Necrosis Morphology of certain viruses of Salmonid Fishes. I. in vitro studies of some viruses causing Hematopoietic Necrosis
An electron microscope study was performed on three virus isolates that caused hematopoietic necrosis in salmonid fishes: infectious hematopoietic necrosis (IHN), Oregon Sockeye Disease (OSD), and Sacramento River Chinook Salmon Disease (SRCD). All three isolates were examined by negative staining of fathead minnow (FHM) monolayer tissue culture concentrates and IHN virus was also...

An obscure disease of rainbow trout An obscure disease of rainbow trout
An annul mortality among Rainbow Trout (Salmo gairdneri) has plagued the Shelton Hatchery of the Washington State Department of Game for the last several years. No infectious agent could be isolated from the moribund fish, but histopathologica1 changes in the liver of 1-month-old fish suggested the presence of a toxic substance. Scoliosis in 3-month-old fish suggested a possible...

Precipitating antibody against Aeromonas salmonicida in serums of inbred albino Rainbow Trout (Salmo gairdneri) Precipitating antibody against Aeromonas salmonicida in serums of inbred albino Rainbow Trout (Salmo gairdneri)
Precipitins in albino rainbow trout serums were demonstrated by gel diffusion after a single parenteral exposure to the soluble antigens of Aeromonas salmonicida. The fraction of the serum containing antibody activity against the presented antigens was shown by immunoelectrophoresis to be in the nonmigrating region. This corresponded to the beta-2 fraction of rabbit serum. An antibody...

Stress of anesthesia with M.S. 222 and Benzocaine in Rainbow Trout (Salmo gairdneri) Stress of anesthesia with M.S. 222 and Benzocaine in Rainbow Trout (Salmo gairdneri)
Rainbow trout (Salmo gairdneri) anesthetized with M.S. 222 for periods up to 12 min experience interrenal ascorbate depletion, uremia, and moderate hypercholesterolemia. Anesthesia with neutralized M.S. 222 (pH 7) or benzocaine prevented these changes and significantly reduced the variability in plasma glucose, cholesterol, and cortisol, indicating that the stress of anesthesia with M.S...

Occurrence of whirling disease of trout in western United States Occurrence of whirling disease of trout in western United States
Whirling disease of trout, caused by Myxosoma cerebralis, was diagnosed in 1966 for the first time in rainbow trout (Salmo gairdneri) from California and Nevada hatcheries. In 1969 the first incidence of this disease in cutthroat trout (S. clarki) was reported in Nevada. To date these have been the only confirmed cases of whirling disease in western United States.
