Filtering by: Subject Chinook salmon -- Oregon -- Willamette River Watershed -- Growth

Early self-sorting behavior in Chinook salmon is correlated with variation in growth, behavior and morphology later in life.

Creator:

Unrein, Julia R.

Abstract:

Juvenile Chinook salmon (Oncorhynchus tshawytscha) exhibit an array of life history tactics in Oregon's Willamette River Basin, yet we do not know to what extent it is driven by phenotypic plasticity or whether it is predetermined and how conditions in the early rearing environment may affect phenotype expression. We have...

CHINOOK SALMON IS CORRELATED WITH VARIATION IN GROWTH, BEHAVIOR AND MORPHOLOGY LATER IN LIFE
Distribution and coinfection of microparasites and macroparasites in juvenile salmonids in three upper Willamette River tributaries

Creator:

Roon, Sean Robert

Abstract:

Wild fish populations are typically infected with a variety of micro- and macroparasites that may affect fitness and survival, however, there is little published information on parasite distribution in wild juvenile salmonids in three upper tributaries of the Willamette River, OR. The objectives of this survey were to document (1)...
