Age, growth, and diet of fish in the Waldo Lake natural-cultural system

Creator:: Swets, Nicola L.
Abstract:: Waldo Lake, located in the Oregon Cascades, is considered to be one of the most dilute lakes in the world. Even with very low nutrient concentrations and sparse populations of zooplankton, introduced fish in the lake are large in size and in good condition when compared to fish from other...

Habitat relationships of native and non-native fishes of the Willamette River, Oregon

Creator:: Williams, Joshua E.
Abstract:: The Willamette River flows north between the Cascade Mountains and Coast Range of western Oregon within a 29,728-km² basin. The fish community in the geologically young basin consists of 36 native species, but introductions of non-native fishes have added 33 additional species for a total of 69 fish species. During...

Patterns and Processes of Fish Dispersal and Settlement along the Oregon Coast

Creator:: Ottmann Riera, Daniel
Abstract:: Most benthic marine organisms have a bipartite life with an early pelagic stage that enables dispersal of offspring, connecting spatially separated populations, and a late stage where individuals reside in a benthic habitat. Settlement of pelagic offspring to bottom associated substrates is the process that connects the two life history...

Relationships among in-stream physical habitat, land use, and geology in small coastal streams of northern Oregon

Creator:: Scott, Larissa E.
Abstract:: Salmonid populations in the Pacific Northwest are at historic lows and many populations continue to decline. Previous studies have linked salmonid declines to land use through degradation of in-stream physical habitat, but few of these studies have taken geology into consideration. This study relates habitat parameters known to be important...

Distribution of fishes and their relationships to environments in selected coastal streams, Douglas and Coos Counties, Oregon

Creator:: Duke, Stephen D'Wayne
Abstract:: This study was an investigation to determine the distribution, abundance and general food habits of salmonids and non-game fishes residing in several selected coastal streams, Douglas and Coos Counties, Oregon. The physical conditions that characterize the various stream habitat types were monitored and the influence of physical conditions on the...

Distribution of fishes in tributaries of the lower Columbia River

Creator:: Reimers, Paul E.
Abstract:: During 1963 and 1964 collections were made in tributaries of the lower Columbia River and literature was reviewed to compile a list of fishes from that area. Based on available sources and collections in this study, a total of 28 families and 77 species are known from the lower Columbia...

Effects of forest management on fish habitat and macroinvertebrates in northeast Oregon streams

Creator:: Carlson, Joan Y.
Abstract:: This study describes streams in the Blue Mountains and Wallowa Mountains of Northeastern Oregon in order to characterize the interactions between the terrestrial and aquatic ecosystems and to determine how logging affects those relationships. Five stream reach pairs, each consisting of an undisturbed reach and a similar reach flowing through...

The influence of some environmental factors on the distribution of fishes in Upper Klamath Lake

Creator:: Vincent, David Thomas
Abstract:: The fishes of Upper Klamath Lake appeared to distribute themselves in three general groups during the summers of 1964 and 1965: (1) the chubs--unrestricted as to distribution with slight seasonal variations; (2) rainbow trout and yellow perch -- restricted to certain water conditions that exist only along the northern marsh...

Food habits and species composition of neritic reef fishes off Depoe Bay, Oregon

Creator:: Steiner, Richard George
Abstract:: The distribution and trophic ecology of neritic reef fishes was studied to provide biological information useful in conserving these stocks. Houk and line fishing was conducted from July 1976 to July 1977 on neritic reefs within 5 km of the Oregon coast adjacent to Depoe Bay. Sampling was designed to...
