Much of this report is concerned with the perennial question of when crabs are in the soft-shell state, as opposed to when the commercial fishing season should be open. Other topics covered include molted crab shells, methods of measuring crab shells to determine if they meet size limits, early growth...

The lower Deschutes River of northcentral Oregon has a historically uniform discharge record. Significant reductions in discharge below the seasonal norms will degrade the environment for migratory and resident salmonids by increasing siltation and gravel compaction, and by reducing intragravel water dissolved oxygen content. Fish spawning will be limited by...
This report is a description of the neoplasm disease affecting the native oyster and bay mussel in Yaquina Bay. It lists actions taken to study the disease further, and assures the public that the disease is under control.
This document contains a result of a study to determine the role of hatchery-reared winter steelhead in steelhead fisheries. The study examines the contribution of these salmon ‘with respect to’ angling intensity, number of fish stocked, contribution of native stocks, and several other factors. It also investigates survival of hatchery-reared...

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...
In a paper now in press as a Bulletin of the U. S. Fish and Wildlife Services the writer has discussed the downward trend of the catch of Columbia River Chinook salmon since 1920 and has stated that the decline is doubtless an indication that the runs of this species...
Samples, consisting of scales, length and weight measurements, and sex determinations of chum, pink, and silver salmons, were taken from the commercial catch in the Columbia River in 1914. Five hundred eighteen chum scales were examined. All fish had gone to sea early in their first year; and 70.5 percent...
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...
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...
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....
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...

Greater sage-grouse (Centrocercus urophasianus) were once found in most grassland and sagebrush (Artemisia spp.) habitats east of the Cascades in Oregon. European settlement and conversion of sagebrush steppe into agricultural production led to extirpation of the species in the Columbia Basin by the early part of the 1900s, but sagebrush...
