The Pacific salmonid species Oncorhynchus mykiss is separated into a migratory form (steelhead trout) and a
non-migratory form (rainbow trout). A decrease in water temperature is likely a cue triggering downstream
behavior in the migratory form, and testosterone inhibits onset of this behavior. To elucidate differences in
sensitivity to water...
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 measuring immunocompetence of fish. In the first chapter, the Alamar Blue assay was...
