Spawning coho, chinook, and chum salmon are annually surveyed in coastal streams by Department of Fish and Wildlife personnel. Annual peak counts of spawning salmon provide data for computing an index of coastal escapement which is plotted each year to chart spawning salmon trends over a period of years. This...
Fish Commission of Oregon personnel seined selected locations of Tillamook Bay, Oregon, from June to September 1972, to determine if juvenile salmon were rearing in the estuary and to get some concept of relative numbers of fish in the various parts of the bay. These data then could be compared...
A study of the distribution, relative abundance and diet of
fishes sympatric with juvenile sockeye salmon, Oncorhynchus nerka
(Walbaum), within the freshwater nursery areas of the Naknek River
system was undertaken from 1961 to 1963. The study was part of an
extensive investigation to determine what factors in the freshwater...

A group of trout that reside in streams of the desiccating lake
basins of southeastern Oregon differ markedly from other known
Salmo. Known commonly as the red-band trout, this fish was subjected
to chromosome analysis for comparison with other species of
western North American Salmo. The karyotype of the red-banded...
Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...
