The Willamette River Spring Chinook Sport Fishery, 1947

Creator:: Johnson, Donald R. and Jensen, Christopher
Abstract:: "The Willamette River has the largest runs of spring chinook salmon of any tributary of the Columbia River rising in Oregon. The run to the Willamette is most unique in that the migrating fish pass up the river through Portland, a city of several hundred thousand people, and support a...

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...

Willamette River Floodplain 100 Meter Slices Framework Technical Details: Juvenile Spring Chinook Habitat ca. 2010

Creator:: University of Oregon. Institute for a Sustainable Environment and Enright, Chris
Abstract:: The SLICES framework is intended for use in making decisions about conservation and restoration in the Willamette River floodplain. It makes use of distinct spatial units, called slices, for planning and tracking change in the floodplain. The Juvenile Spring Chinook Habitat ca. 2010 Technical Report describes the two associated attributes...

Cool, pathogen free refuge lowers pathogen associated prespawn mortality of Willamette River Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Benda, Susan
Abstract:: Spring Chinook salmon, Oncorhynchus tshawytscha, are transported above dams in the Willamette River to provide access to blocked spawning habitat. However, 30-95% of these transplants may die before spawning in some years. To varying degrees, salmon in other tributaries--both blocked and unblocked--have similar prespawn mortality (PSM). Our study determined if...

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)...

The 1972 Willamette River Spring Chinook Sport Fishery

Creator:: Collins, Melvin D. and Massey, Julius B.
Abstract:: The main objective of this program is to determine the number of spring chinook annually caught by the sport fishery from the Willamette River below Oregon City and from Multnomah Channel. This information, when combined with the Clackamas River catch and calculated Willamette Falls and Clackamas River escapements, provides an...

Studies of the scales of Umpqua River spring chinook salmon

Creator:: Saltzman, Bill
Abstract:: A study of the scales of Umpqua River spring chinook salmon was made from mid-September to December 1, 1951. The study was undertaken to determine the age composition and probable life history of spring Chinooks in this river. The study was made at the Oregon State College Fisheries Research Laboratory...
