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....
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...
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...
"One of the basic problems of forest management is that of restoring to
productivity denuded areas which cannot be expected to restock through natural means.
The most efficient method of regenerating such lands is that method which
provides adequate restocking in the shortest time with the least expense. Successful
direct...
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 author collected scales from angler-caught steelhead trout during the winter of 1941-1942. This data was supplemented with data from commercially gill-netted steelhead collected January 30-February 28, 1942. Most fish came from the lower Tillamook Bay or the lower Wilson River. The author examined size, growth pattern, age and sex,...
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 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...
