This investigation was a trial to check the possibility of developing a frozen blackberry puree dessert. A blend of different varieties and selections of blackberries, as it may be expected in commercial production was preferred to provide the fruit-puree-mix.
Several stabilizers bearing different commercial names were added to the fruit...
This paper is the result of extensive experiments, investigating the effect on typical distribution transformers when operated overexcited as much as 117% of their rated voltage.
This 1957 progress report will be concerned with results of the use of herbicides on pole beans, sweet corn, and table beets in trials at Corvallis. The plots were evaluated for effectiveness of weed control by these herbicides as well as their effects on yield. These results are to be...
The object of this report is to discuss the following shellfish regulation problems: 1) offshore crab seasons; 2) minimum size and gear for commercially-caught bay crabs; 3) and the gaper clam season in Coos Bay. These regulations have received some criticism recently and are scheduled to be discussed at the...

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,...
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...
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....
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...
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...
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...
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...
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...
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...
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...
Oregon State University operates a World Wide Standard Seismograph
Station at Corvallis (COR) and a seismic station at Klamath Falls (KFO),
Oregon. Data recorded at the Portland (PTD), Oregon, seismic station,
operated by the Oregon Museum of Science and Industry, are included in
this Seismological Bulletin.
The Corvallis station includes...
July 1, 1952-June 30, 1954. Report of the Oregon Game Commission’s transactions and operations for 1952-1954. Because of its importance, water for fish and wildlife is the focus of this report, and discussion of this topic is included in nearly every section. The first half of the report discusses game...
This report contains the results of standardized screening for the 1952 year-class of young razor clams. It also contains data regarding the age composition of the catch, a description of the marking program for 1952, and an analysis of recoveries by both sport and commercial fisheries.
This bulletin provides a brief description of 8 different clams most commonly harvested in Oregon, delineating average depth and distribution as well as common harvesting techniques for each clam. The bulletin also describes the bays and rivers affected by tidal action, and their clam beds.
This document contains a discussion by the biological staff of the proposed regulations for the July 13 Fish Commission hearing, and examines potential effects of allowing the use of Razor Clams as crab bait.
This report is an update of shellfish investigations from June 1 to December 31, 1953. It includes a summary of bay clam and crab investigations, including details on oyster pests in Oregon and crab production for 1952. It also summarizes a survey on commercial razor clam production in Lincoln County...
This progress report contains updates on two phases of the razor clam investigations. The report focuses on length frequency data on the 1949-50 set of young clams, including graphs and figures, but also has a section on the abundance, mortality, and growth of the 1949 year class.
