Eight scale characters of known hatchery and wild coho salmon
(Oncorhynchus kisutch) were compared, and a linear discriminant
function was used to determine if hatchery and wild adult coho
salmon could be correctly identified by their scales....

Abstract.- Increasing the abundance of salmon in coastal Oregon rivers and streams
is a high priority public policy objective. Salmon runs have been reduced from pre-development
conditions (typically defined as the 1 850s), but it is unclear by...

Laboratory studies were conducted on the food consumption, growth, and bioenergetics of juvenile coho salmon (Oncoynchus kisutch) held at various swimming velocities and dissolved oxygen
concentrations at 15 C. Food consumption and growth of...

As highlighted in this study, shallow-water habitats and the prey they provide are important for juvenile salmon in the Columbia River estuary, but the spread of invasive species and large-scale changes to the estuary influence how these habitats...

To test the utility of otolith chemical composition as a tool for determining the natal stream of origin for salmon, we examined water chemistry and otoliths of juvenile and adult Chum Salmon Oncorhynchus keta and Coho Salmon O. kisutch from three...

In this thesis, we examined the effects of the exposures to anthropogenic
pollutants on the fish, primarily juvenile chinook salmon, immune system using newly
and recently developed immune assays. In addition, we developed a new assay for...

The primary objective of this study was to identify
and investigate the underlying basis for variation in the
volume of exports of Canadian chum salmon during 1954-1975
period. A number of factors thought to be of importance
in the determination...

The relative resistance of the coho salmon (Oncorhynchus kisutch) and the chinook salmon (O. tshawyscha) to the parasitic larvae (glochidia) of the freshwater mussel (Margaritifera margaritifera) was studied in an attempt to determine why the coho...

Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were...

Much of what is recommended to benefit salmon is what has been needed for a long time and what many have known was needed. More than
50 years ago, federal biologists warned that the consequences of continuing habitat degradation and additional...
