An improved girthometer for studies of gill net selectivity
Richard S. Wydoski, David R. Wolfert
1968, Progressive Fish-Culturist (30) 62-64
Gill nets are effective for collecting samples of many fish species. These nets may be highly selective in their catch, depending on the mesh size or sizes used and on the size distribution and body shape of the fish in the population. Early studies related mesh selectivity to...

Silver-bearing black calcite in western mining districts
D. F. Hewett, A. S. Radtke
1967, Economic Geology (62) 1-21
The name black calcite has been applied from time to time to a dark gray to black variety of calcite or aragonite in metalliferous ore deposits in the Western States. Most of the material shows curved, roughly rhombic cleavage. The color is due to dispersed minute grains of one or...

A closed recirculated sea-water system
1967, Progressive Fish-Culturist (29) 133-139
Study of a virus disease in the chinook salmon (Oncorhynchus tshawytscha) necessitated the use of a marine environment to study the long range effects of the disease and to complete the life cycle of its etiologic agent. A closed recirculated sea-water system was designed for use under experimental laboratory conditions so...

1967, Research Briefs: Fish Commission of the State of Oregon (13) 20-24
The absorption of sulfamethazine by yearling spring chinook salmon (Oncorhynchus tshawytscha) was compared when administered in the Oregon Pellet and a fish-meat diet. The pelleted diet delivered the drug to the fish approximately twice as efficiently as the fish-meat diet. Dosage levels are recommended for both diets, and the efficacy...
Nutritionally induced hepatomagenesis of rainbow trout (Salmo gairdneri)
