The end of the European phase of the war lessens somewhat the demands on the military for food in one theater of operations. The successful prosecution of the Pacific phase of the war and the needs of the liberated peoples of the world, plus the civilian requirements of the allied...
Between 43° 17' and 43° 21' north latitude along the south-central coast line of Oregon lie the collecting grounds adjacent to the Oregon Institute of Marine Biology. These 10 miles of coast line, between Coos Bay and Cape Arago, provide an assortment of intertidal environments ranging from the protected brackish...
The area studied in detail, known as the Antone District,
is located in the southeast corner of Wheeler County, Oregon, ,
between longitude 119 37. and 119°54 east, and latitude 44°23
and 44°3O' north.
Surface elevations range from 3050 feet above sea level in
the northeast corner of the district,...
Semi chemical pulping processes, using both acid and neutral sulfite liquors, were ap!)lied to the following six Arkansas Delta hardwoods: black willow, southern cottonwood, American elm, sugarberry, green ash, and bitter pecan. Pulping conditions for yields of 75 to 80 percent were determined and the properties of both the pulps...
Hardwoods, including aspen, comprised 22 percent of the pulpwood. received in the New York and New England States pulp mills in 1944 when war-time conditions favored the use of all available wood. The denser hardwoods alone, however, amounted to only 9 percent of all the pulpwood, and this value is...
Exceptional data are available for the study of the salmon runs of the Columbia River in 1938. Detailed figures on catch were supplied by Oregon and Washington in such form that they could readily be combined with the counts at Bonneville Dam to provide a basis for estimating the escapement....
1. Six major types of commercial gear have been used to take salmon and steelhead on the Columbia River; namely, gill nets, set nets, seines, traps, fish wheels and dip nets. 2. The five important commercial species in the Columbia River are chinook, silver, blueback and chum salmon and steelhead...
A study of the fishery problems raised by the construction of the Grand Coulee Dam on the upper Columbia River was done. Part of the study was to estimate the number of salmon taken in commercial fishery for the purpose of comparing this with the number counted as they passed...
The salmon runs of the Columbia River constitute one of the most important natural resources of the states of Oregon and Washington. Thousands of people are dependent, wholly or in part, upon these resources for their livelihood; and their welfare is dependent upon the maintenance of the salmon runs. It...
The salmon of the Columbia River have supported an intensive fishery for over seventy years but are now showing unmistakable signs of depletion, and various factors are contributing to the rapid progress of this condition. Five species of fish enter into the commercial fishery on the Columbia River itself. These...
Samples, consisting of scales, length and weight measurements, and sex determinations of chum, pink, and silver salmons, were taken from the commercial catch in the Columbia River in 1914. Five hundred eighteen chum scales were examined. All fish had gone to sea early in their first year; and 70.5 percent...
In a paper now in press as a Bulletin of the U. S. Fish and Wildlife Services the writer has discussed the downward trend of the catch of Columbia River Chinook salmon since 1920 and has stated that the decline is doubtless an indication that the runs of this species...
The temperate water fisheries for albacore in the North Pacific seem to exploit somewhat similar segments of the respective populations present in the various localities. It is clear that in most of the exploited populations two or at most three year classes are highly dominant. In the California fishery from...
During an oceanographic cruise of the "E. W. Scripps" in May, 1939, off the coast of Oregon, four small, post-larval specimens of Anoplopoma fimitrita were taken at the surface of the sea with a dip net at two of the hydrographic stations off Cascade Head, Oregon.
A symposium presented before a joint meeting of the
American Society of Ichthyologists and Herpetologists
and the Western Society of Naturalists at Stanford University
on June 29, 1939, and published as a special issue
of the Stanford Ichthyological Bulletin through the cooperation
of the Fish Commission of the State of...
This report is a summarization of investigational work that has been completed since 1941 by the Oregon State Game Commission on the coast streams south of the Columbia River, exclusive of the Umqpua and its tributaries. The Umpqua river system was covered in another report prepared jointly by biologists of...
July 1, 1942-June 30, 1944. Consists largely of tables summarizing various hatchery and game farm expenditures, numbers of trout handled at different life stages and locations, and also game fish/pheasants liberated.
This report contains additional information on improvements of the Siletz River Bar. It includes information on nearby tributaries, as well as the growing annual yield of timber from the area and potential related commerce such as the Oregon Pulp and Paper Company.
This report focuses on the stocks of Silver (Coho) and Chinook salmon in Tillamook and Coos Bays, as well as Nehalem, Siletz, Yaquina, Alsea, Siuslaw, and Coquille Rivers. It gives a brief history of Oregon fisheries in general, then delineates and analyzes the yearly landings of each fishery for Silver...
By 1948, Oregon’s clamming regulations spilled over into fifty-one different sections of administrative rules. They were “cumbersome” at best. The previous legislative session had repealed many outdated laws but kept them in effect until the Fish Commission could study the issue and propose new regulations. The Commission had been studying...
Best available copy. Originally published as part of Shellfish investigation progress report no. 4. “In the spring of 1947, importation of Pacific oyster seed from Japan was resumed for the first time since before the war. Major plantings of this seed were made in Tillamook and Coos Bay with additional...
The purpose of this study is twofold: first, the construction of a major framework outlining a functional curriculum in professional forestry and, second, the suggesting of a method of procedure that will enable a staff in any forestry school to develop a functional curriculum adapted to local needs. No attempt...
