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...
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.
The Fish Commission of Oregon was tagging Dungeness crabs in the late 1940s and early 1950s to see how far the crabs moved between moltings. This document gives data on crab tags retrieved between November 21, 1947 and February 21, 1950. Some crabs were indeed wanderers: crabs released in the...
The plan of the present study was as follows:
1. A survey was made of professional textbooks dealing with methods of teaching science and biology. Only books published since 1920 were used.
2. Recently published high school textbooks, workbooks and laboratory manuals, and teachers' guides were reviewed for teaching aids....
The objectives of this study include an attempt to determine what broad fields of education are most essential to the welfare of Orissa in the light of her intense current problems. It must suggest definite goals and areas for study by the adults of the province. Some development of the...
The object of the experiments described in this report was to develop the use of Oregon material to produce a low-cost flux for commercial ceramic use. The materials tested include volcanic ash, pumice, and, a material new to the ceramic field as a flux, perlite. These materials were combined with...
In 1949, the Army Corps of Engineers dredged Coos Bay. “Despite objection of local residents, commercial clam diggers, and the Fish Commission” the Corps dumped dredging spoils on a commercially important clam bed, and destroyed much of it. “This year, with an earlier start and more data, it is hoped...
This report contains a series of individual reports within it. The main report continues growth and aging studies on fat gaper clams in Yaquina Bay. This document also includes a report on other Fish Commission activities on the Coast, a summary of razor clam research, the beginning of a survey...
An excellent opportunity was afforded to observe growth of horseclams of the one-year-plus class when it was discovered April 7, 1950, that a newly formed mud flat in Yaquina Bay, formed September and October 1948 by fill from dredging operations, had thousands of young horseclams embedded in it.” (p.1) Growth...

Should fishing by crab pots instead of crab rings be allowed in certain bays in Oregon? An error caused the ban on crab pots to be deleted from the statutes. This 1950 paper considers whether the ban on crabpots should be reinstated in Siletz, Yaquina and Alsea Bays. This is...
