Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...

Morphological and meristic characteristics of ten populations of blackside dace, Rhinichthys osculus nubilus (Girard ), from western Oregon

Creator:: Zirges, Malcolm H.
Abstract:: Blackside dace, Rhinichthys osculus nubilus (GIRARD), were collected from ten western Oregon streams and examined for variation among morphological and meristic characters. Several characters were observed to vary between populations studied. Number of vertebrae, number of scales in and above the lateral line, length of snout, and depth of body...

Behavior and survival of coho salmon, Oncorhynchus kisutch (Walbaum), in Sashin Creek, southeastern Alaska

Creator:: Crone, Richard Allan
Abstract:: Behavior and survival in fresh water were studied for three brood years of coho salmon in Sashin Creek, Alaska, from October 1963, until September 1966. Investigations of spawning adults were conducted to determine numbers of spawners, distribution on the spawning grounds, effects on pink salmon, age composition, redd life, fecundities,...

The migratory pattern of audlt sockeye salmon (Oncorhynchus nerka) in Bristol Bay as related to the distribution of their home-river waters

Creator:: Straty, Richard R.
Abstract:: The individual stocks of sockeye salmon that make up the annual spawning migration to the Bristol Bay region of Western Alaska are produced in the lakes and streams of ten major river systems, which discharge into the bay over a shoreline distance of 120 miles. The hypothesis adopted in this...

Limnology of Upper Klamath Lake, Oregon, with emphasis on benthos

Creator:: Hazel, Charles R.
Abstract:: Aspects of the limnology and benthic ecology of Upper Klamath Lake, Oregon, are described emphasizing those features that identify its uniqueness. The lake is large, shallow, and characterized by nuisance abundances of Aphanizomenon flos-aquae and midge flies. Results of this study indicate that it does not stratify and dissolved oxygen...
