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...
A graph is presented which shows the average annual temperature depth profile which has been computed and estimated for the
Brownlee Reservoir. Forecast computations and estimations are
for a median river flow year. The graph also contains forecasts
of the annual temperature cycle for the Snake River below Brownlee Dam.
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...
The purpose of this thesis was to evaluate two methods of estimating 1953 costs of producing strawberries. To accomplish this the following steps were taken: 1. To estimate production costs in 1953 by using 1947 input data and 1953 prices for those inputs, (Method 1); 2. To compare the results...
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...
The Fishery Division of the Oregon State Game Commission
continued in 1950, with activities of previous years embraced under
the general categories of research, management, and production. Some
activities were expanded or added where a need arose, and others were
reduced or eliminated. In general the over —all program followed...
