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...

The effects of the herbicides Diquat and Dichlobenil on pond invertebrates

Creator:: Wilson, Dennis Carl
Abstract:: The acute toxicity of Diquat (1:1-ethylene-2:2' dipyridylium dibromide) and Dichlobenil (2, 6-dichlorobenzonitrile) to six selected pond invertebrates was determined using the median tolerance limit estimation method. Diquat was more toxic to the amphipod, Hyalella azeteca than to the aquatic insects Callibaetis, Limnephilus, Enallagma, Libellula, and Tendipedidae. The addition of mud...

The influence of some environmental factors on the distribution of fishes in Upper Klamath Lake

Creator:: Vincent, David Thomas
Abstract:: The fishes of Upper Klamath Lake appeared to distribute themselves in three general groups during the summers of 1964 and 1965: (1) the chubs--unrestricted as to distribution with slight seasonal variations; (2) rainbow trout and yellow perch -- restricted to certain water conditions that exist only along the northern marsh...

The black crappie, Pomoxis nigromaculatus, as a farm pond fish in Oregon

Creator:: Stolte, Lawrence
Abstract:: The black crappie was evaluated as a pond fish in four experimental ponds in the Willamette Valley. Two ponds were stocked with largemouth bass, bluegill sunfish, and black crappie (1:9:3), and two ponds with largemouth bass and black crappie (1:3). Total biomass was greatest in the three-species ponds (80 kg/...

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...

Growth of channel catfish, Ictalurus punctatus (Rafinesque), fed artificial diets in ponds near Corvallis, Oregon

Creator:: Suraswadi, Plodprasop
Abstract:: The experiment was conducted at the Soap Creek farm ponds near Corvallis, Oregon. Oregon Moist Pellet and Purina Trout Chow at three different rates of feeding for each diet were used to feed fingerling channel catfish stocked at the rate of 1,000 per acre. A complete random design and Fisher's...

Some aspects of the comparative ecology of fishes associated with juvenile sockeye salmon, Oncorhynchus nerka (Walbaum), in the lakes of the Naknek river system, Alaska

Creator:: Wallace, Richard L.
Abstract:: A study of the distribution, relative abundance and diet of fishes sympatric with juvenile sockeye salmon, Oncorhynchus nerka (Walbaum), within the freshwater nursery areas of the Naknek River system was undertaken from 1961 to 1963. The study was part of an extensive investigation to determine what factors in the freshwater...

A review of the deep water Liparidae from the coast of Oregon and adjacent waters

Creator:: Stein, David L.
Abstract:: Descriptions and distributions are given of 28 species of Liparidae occurring or possibly occurring below 200 m between San Francisco and northern Vancouver Island, with keys for their identifications. Nine genera are included: Careproctus, Elassodiscus, Lipariscus, Nectoliparis, Rhinoliparis, Acantholiparis, Paraliparis, and two new genera are described, Odontoliparis and Osteodiscus. Eight...

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...

Abstract:: Complete, identified, developmental series of larval cottids Artedius fenestralis, A. creaseri, A. meanyi, Oligocottus snyderi, Clinocottus embryum, and C. globiceps are described for the first time. In addition, redescriptions of four species, Artedius harringtoni, A. lateralis, Oligocottus maculosus, and Clinocottus acuticeps are included that provide new and comparative information on...

Trophic adaptations and relationships of rockfishes (Sebastes spp.) of Oregon

Creator:: Pequeño, Germán E.
Abstract:: A comparative analysis of structures related to capture and processing of food, in 624 specimens belonging to 31 species of Sebastes of Oregon was made. The structures studied were the following: the tooth-bearing bones (premaxillary, dentary, vomer, palatine); the maxillary, angular, articular, parasphenoid and glossohyal bones; the lower limb of...

Age-fecundity relationships in the striped seaperch Embiotoca lateralis from Yaquina Bay, Oregon

Creator:: Swedberg, Stephen Ernferd
Abstract:: A study was conducted at Yaquina Bay, Oregon, to determine the age-fecundity relationships in the striped seaperch Embiotoca lateralis. A questionnaire was sent to California, Oregon, and Washington to ascertain what regulations were in effect, and the value of the family Embiotocidae with regard to the sport and commercial harvest....

The chronic toxicity of 2,3,7,8-tetra-chlorodibenzo-p-dioxin (TCDD) to five selected aquatic organisms

Creator:: Miller, Richard A.
Abstract:: Five species of aquatic organisms were exposed to TCDD. Lethal effects of initial exposure to coho salmon of 23.4 nanogram TCDD/gram fish wet weight (23.4 ng/g), or equivalent to 100 nanogram per liter (100 ng/l) TCDD in water, for 24 hours were irreversible; 95% mortality occurred in 60 days. Exposure...

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,...
