The behavior and stream habitat utilization of juvenile hatchery-reared coho salmon (Ovicozihynchus kisutch) and wild cutthroat trout (Salmo clarki) were examined to assess the nature of interactions between the species potentially resulting from introductions of hatchery coho salmon in streams. Habitat utilization was monitored in Mill Creek, Polk Co., Oregon...
A photon-counting technique which provides direct digital read-out
of data has been developed and evaluated for the reaction rate determination
of glucose. The enzyme catalyzed oxidation of glucose
to gluconic acid and hydrogen peroxide with the subsequent reaction of
hydrogen peroxide with excess iodide to produce tri-iodide is followed
by...
A self-powered neutron detector (SPND) is a device that, coupled with a current meter, provides a readout proportional to neutron population. This thesis discusses the design parameters of an array of such devices, their characteristics, and the use of these devices as a self-powered neutron spectrometer (SPNS) to provide information...
Various aspects of the energetic response to handling stress in juvenile
coho salmon (Oncorhynchus kisutch) were examined. Fish were subjected to
four different handling stressors in a Blazka-style respirometer. Stressed fish
had rates of oxygen consumption that were higher than controls. The
magnitude of the increase ranged from 139 to...
The purpose of this investigation was to determine the nature of the
chemical constituents of incense cedar bark with the hope that such an endeavor
would spur future research, development and use of a now neglected
natural raw material.
The bark from nine trees, which were separated into three age...
