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.
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...
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...
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...
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.
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....
