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...

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/...

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...

Seasonal distribution and environment of adult Pacific herring (Clupea harengus pallasi) near Auke Bay, Lynn Canal, southeastern Alaska

Creator:: Carlson, Harry Richard
Abstract:: The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a...

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...

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...

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...

A dwarfed population of Catostomus rimiculus (Catostomidae: Pisces) in Jenny Creek, Jackson County, Oregon

Creator:: Hohler, David Berry
Abstract:: The population of Catostomus rimiculus from Jenny Creek basin is identified as a dwarfed derivative of the normally much larger C. rimiculus from the Klamath and Rogue River systems. C. rimiculus in Jenny Creek basin are separated from those in the Klamath by a series of 3-10m waterfalls resulting from...
