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 microscopy

Use of a portable electric barrier to estimate Chinook salmon escapement in a turbid Alaskan river
We developed a portable electric barrier to aid in the capture of adult chinook salmon Oncorhynchus tshawytscha undergoing spawning migrations up a turbid stream in south-central Alaska. In 1981, we tagged and released 157 chinook salmon after diverting them from the main-stem Killey River into a conventional trap with the aid of the electric barrier. On the basis of returns of tagged salmon to Be

Effect of differential gastric evacuation and multispecies prey items on estimates of daily energy intake in juvenile Chinook salmon
The caloric density of stomach contents in juvenile chinook salmon,Oncorhynchus tshawytscha, was not affected by gastric evacuation, suggesting a constant caloric density of stomach contents during evacuation. Differences in the caloric density of prey consumed did affect caloric density of stomach contents over a 24-h period. Consumption of the amphipodCorophium sp. was associated with reduced ca

Histochemistry of leucine aminoaphthylamidase (LAN) in rainbow trout (Salmo gairdneri)
The histochemistry of leucine aminonaphthylamidase (LAN) was studied in frozen tissue sections of rainbow trout both in yearling and adult fish. Age of fish had relatively little effect upon the results. The most intense LAN color production was in epithelial cells of midgut, pyloric ceca, hindgut, and in some segments of kidney tubules. Lower levels of LAN were evident in liver cells of Kupffer,

Dietary Factors and Hepatoma in Rainbow Trout (Salmo gairdneri). I. Aflatoxins in Vegetable Protein Feedstuffs
Aflatoxins (toxic metabolites of the mold Aspergillus flavus) were present in a commercial trout ration causing hepatoma in rainbow trout. Cottonseed meal and solvent extracts of cottonseed meal and of rations containing cottonseed meal and peanut meal were found by chemical assay and confirmed by duckling assay to contain aflatoxins. Diets containing these materials and a purified test diet to wh

Mycobacterium salmoniphilum sp. nov. from salmonoid fishes
The presence of mycobacteria in salmonoid fishes was first recorded by Earp, Ellis, and Ordal (1) in 1953. Acid-fast bacilli had previously been reported from other cold-blooded animals including fishes of fresh-water and marine origin; recent reviews have been presented by Vogel (2) and Parisot (3).
The initiation of an intensive search for bacteria of this group revealed their widespread distrib
