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...
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...
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...
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.
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...
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....
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...
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...
The species of anadromous fish entering the Umpqua River are: chinook salmon (spring, summer, and fall runs), silver salmon, steelhead trout (summer and winter runs), cutthroat trout, shad, striped bass and sturgeon. The winter steelhead, striped bass, and shad runs appear to be maintaining themselves. The runs of the other...
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...
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...
1. There is no evidence of a decline in the striped bass population of Coos Bay.
2. The striped bass, a species introduced to the West Coast of North America, has been important as a recreational and commercial fish in Coos Bay since the late 1920s. The catch has ranged...
Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...
In spite of the progressive restrictions of the commercial river fishery during the past fifty years, the trend of the salmon populations of the coastal rivers has been downward. It is almost impossible to isolate and analyze separately the causes of this decline, and any attempt to saddle one factor...
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...
1. The Indians at Celilo Falls catch an average of over 2,600,000 pounds of fish each year, in dip nets in a manner very much the same as used by their ancestors. 2. The bulk of the fish caught at Celilo Falls is from the upriver fall run of chinook...
Tillamook Bay chum salmon are caught commercially by gill-nets, both set and drift, and from 1928 through 1949 the landings have averaged 819,689 pounds per season. More chum salmon are caught on Tillamook Bay than on the rest of the Oregon coastal rivers combined. These fish enter the ocean only...
During a tagging operation conducted in 1951 on the Alsea River, 1,142 adult silver salmon were tagged with plastic Petersen-type tags and stainless steel jaw tags. An attempt was made to determine whether tagged fish released in different apparent conditions suffered differential mortalities. Under the hypothesis that the recovery of...
Ages were determined for 65 fish from the 1947 run and for 287 fish from the 1949 run. In 1947 the percentage composition by age was as follows: 32.3 percent 3-year-old fish, 66.2 percent 4-year-old fish, and 1.5 percent 5-year-old fish. An approximate 95 percent confidence interval for the true...
An average of approximately 200,000 pounds of bay clams were harvested annually in Oregon for the years 1943-49, inclusive. The commercial harvest of bay clams is composed of the gaper, cockle, and softshell clams. The recreational, or noncommercial, harvest of bay clams is composed mainly of the gaper, cockle, softshell,...
A study was undertaken in the fall of 1948 by the Oregon Fish Commission to determine the possible presence and importance of a delay in the migration of adult chinook salmon (Oncorhynchus tshawytscha) at Bonneville Dam on the Columbia River. Approximately 650 chinook were captured, tagged, and released at the...
The objective of the thesis is to present data upon which the management of the Oregon otter-trawl fishery can be based. In addition, a history of the Oregon trawl fishery is presented. A summary of gear development by many of the vessels in the Oregon fleet is presented in table...
In Part I the environment of the coastal dunes of Oregon and Washington is analyzed. Most of the substratum is a narrow foreland or terrace, in part submerged, that borders the mountain front. Temperature is relatively low in summer and rarely reaches the freezing point in winter. Winter precipitation is...
Results of studies beginning in 1947 on the biology of the Dungeness crab (Cancer magister) in Oregon coastal waters are reported. A review is made of the history of the fishery with regard to trend of the catch by magnitude, area, and season; the development and conduct of the fishery...
Tuberculosis in salmonoid fishes was first observed in the 1952 run of fall chinook salmon (Oncorhynchus tshawytscha) returning to the Bonneville Hatchery of the Oregon Fish Commission. In the studies reported here, tuberculosis was found not only in adult spring chinook but in silver salmon (0. kisutch), blueback salmon (0....

This report discusses anticipated problems associated with the pollution of the Umpqua River estuary in Oregon. The method of studying these problems by oceanographical techniques is outlined. Proposed studies relating to the Umpqua River Basin are examined.
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
Oceanographic data collected in the Umpqua River Estuary, Oregon, during the period December 14-15, 1960, are tabulated. Temperature, salinity and velocity were: measured from the surface to the bottom at approximately five-foot intervals at four stations in the estuary. Oxygen samples were collected at depth on four occasions.
Oceanographic data collected in the Umpqua River Estuary, Oregon, during the period January 25-26, 1961, are tabulated. Temperature, salinity, velocity, and oxygen were observed at various depths over one tidal cycle at one station. Temperature and salinity observations were made from the ocean to 11.5 miles upstream upon completion of...
Oceanographic data collected in the Umpqua River Estuary, Oregon, during the period April 26-27, 1961, are tabulated. Temperature, salinity, velocity, and dissolved oxygen were observed at various depths over one tidal cycle at a mid-channel anchor station located near the mouth of the river.
Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
This report presents information concerning the water and related land resources of the Middle Willamette River Basin and is the result of a cooperative study by the U. S. Department of Agriculture and the State Water Resources Board of Oregon.

ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all
have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...
This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile.
Because available data for the Umpqua River...
While the public trust doctrine at common law placed effective limitations on the Crown, these limitations have been somewhat obscured by state court decisions in the United States. Though some courts have suggested that the public trust places limitations or the power of the legislature to convey lands beneath navigable...
The purpose of the Oregon Fish Commission's Columbia River Seal Control Program was to harass seals and reduce their predation on salmon in the river. The effectiveness of the program could not be effectively demonstrated. Fishermen were surveyed and indicated support for not hiring a seal hunter for the following...
