Morphology of certain viruses of Salmonid fishes. II. In vivo studies of infectious Hematopoietic Necrosis Virus Morphology of certain viruses of Salmonid fishes. II. In vivo studies of infectious Hematopoietic Necrosis Virus
Juvenile sockeye salmon (Oncorhynchus nerka) were injected with the infectious hematopoietic necrosis (IHN) virus, and tissue samples from the anterior kidney, spleen, liver, intestine, and pyloric caeca of moribund fish were prepared for electron microscopy. Bullet-shaped virus particles measuring 158 × 90 mμ were observed in the hematopoietic tissues of the anterior kidney and spleen...

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...

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...

Pituitary activation by bacterial endotoxins in the rainbow trout (Salmo gairdneri) Pituitary activation by bacterial endotoxins in the rainbow trout (Salmo gairdneri)
Endotoxins from Escherichia coli and Aeromonas salmonicida caused marked cortisol production in the rainbow trout (Salmo gairdneri).

Stress-induced ascorbic acid depletion and cortisol production in two salmonid fishes Stress-induced ascorbic acid depletion and cortisol production in two salmonid fishes
Interrenal ascorbic acid and serum cortisol were measured in non-specificity stressed yearling coho salmon and rainbow trout.Interrenal ascorbate was markedly decreased during stress but increased to normal if adaptation occurred.Serum cortisol was elevated by non-specific stress and remained high after interrenal ascorbate had returned to initial levels.

Irradiation of fish fillets: Relation of vapor phase reactions to storage quality Irradiation of fish fillets: Relation of vapor phase reactions to storage quality
Fish fillets irradiated under air, nitrogen, oxygen, or carbon dioxide atmospheres developed rancidlike flavors when they were stored at refrigerated temperatures. Packing and irradiating under vacuum or helium prevented development of off-flavors during storage. Significant quantities of nitrate and oxidizing substances were formed when oxygen, nitrogen, or air were present in the vapor...
