Effect of differential gastric evacuation and multispecies prey items on estimates of daily energy intake in juvenile Chinook salmon 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...

Comparison of five techniques for the detection of Renibacterium salmoninarum in adult coho salmon. Comparison of five techniques for the detection of Renibacterium salmoninarum in adult coho salmon.
Samples of kidney, spleen, coelomic fluid, and blood from 56 sexually mature coho salmon Oncorhynchus kisutch were examined for infection by Renibacterium salmoninarum by five methods. The overall prevalence (all sample types combined) of R. salmoninarum in the fish was 100% by the enzyme-linked immunosorbent assay, 86% by the combined results of the direct fluorescent antibody and the...

Basis for managing the harvest of Chinook salmon Basis for managing the harvest of Chinook salmon
On the basis of estimated spawner-recruit relations for populations of chinook salmon Oncorhynchus tshawytscha from British Columbia to California, harvest fractions of 60-70% may be reasonable for stocks for which the productivities are not known. Care should be taken to detect and to avoid excessive harvest from stocks with low productivity.

Macrofauna and environment of the Nanpil-Kiepw River, Ponape, Eastern Caroline Islands Macrofauna and environment of the Nanpil-Kiepw River, Ponape, Eastern Caroline Islands
The first comprehensive evaluation of stream fauna in the Eastern Caroline Islands resulted from collections on Ponape, a 334-km- island having more than 40 streams, many of which arise along 700-m-high interior ridges. Field surveys centered on the Nanpil-Kiepw River below 170 m elevation, a bouldery reach with water of low mineral content and frequent surging flows. Faunal specimens...

Membrane filtration – Fluorescent antibody staining procedure for detecting and quantifying Renibacterium salmoninarum in coelomic fluid of Chinook Salmon (Oncorhynchus tshawytscha) Membrane filtration – Fluorescent antibody staining procedure for detecting and quantifying Renibacterium salmoninarum in coelomic fluid of Chinook Salmon (Oncorhynchus tshawytscha)
We developed a rapid method for detecting and quantifying the pathogen Renibacterium salmoninarum in coelomic fluid of spring chinook salmon (Oncorhynchus tshawytscha) by concentrating the bacteria on 0.2-μm polycarbonate filters and staining them with specific fluorescein-labeled antibody. Centrifugation of samples and resuspension of the sedimented material in phosphate-buffered saline

Summer spawning in the fourhorn sculpin, Myoxocephalus quadricornis, from Alaska Summer spawning in the fourhorn sculpin, Myoxocephalus quadricornis, from Alaska
Histological ovarian analysis indicates summer spawning occurs in Myoxocephalus quadricornis (Fourhorn Sculpin) from Alaska. Previous studies have shown this species spawns during winter in the Baltic Sea; the data presented herein suggests that geographical variation may occur in the timing of spawning of this species.

Genetic variation in chinook, Oncorhynchus tshawytscha, and coho, O. Kisutch Genetic variation in chinook, Oncorhynchus tshawytscha, and coho, O. Kisutch
We used starch-gel electrophoresis to genetically characterize the populations of chinook salmon, Oncorhynchus tshawytscha, and coho salmon, O. kisutch, in the major drainages of the north coast of Washington (the Quillayute, Uoh, Queets, and Quinault Rivers). Of 55 loci examined for electrophoretically detectable variation. 6 were polymorphic (frequency of the common allele was less...
