Spatial and temporal characteristics of bottom-trawl fish assemblages of the continental shelf and upper slope of the Pacific Coast of the United States, 1977-1992

Creator:: Jay, Chadwick V.
Abstract:: Twenty-three bottom-trawl fish assemblages were identified from the relative biomass of 33 dominant species that occurred in the National Marine Fisheries Services' triennial trawl surveys over the continental shelf and upper slope off California, Oregon, and Washington from 1977 to 1992. The assemblages accounted for about 70% of the total...

Growth rates and species composition of juvenile rockfish (Sebastes spp.) in Oregon’s nearshore and estuarine habitats

Creator:: Gallagher, M. Brett
Abstract:: Identification of critical habitat for all life stages of commercially exploited fish populations is critical for effective management. Despite a clear need for basic biological information on juvenile rockfish life history, there have been very few efforts to describe distribution and habitat of this life stage, particularly along the Oregon...

The distribution and aggregation of Chinook salmon stocks on the Oregon Shelf as indicated by the commercial catch and genetics

Creator:: Ireland, Robert
Abstract:: Project CROOS, Collaborative Research on Oregon Ocean Salmon, is a unique partnership of scientists and commercial fishermen that combines catch location data with stock assignments obtained from genetic micro-satellite analysis to investigate the distribution of Oregon Chinook across multiple spatial scales. Using catch data collected by collaborating Oregon troll fishermen,...

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...

Channel morphology and hydraulic characteristics of torrent-impacted forest streams in the Oregon Coast Range, U.S.A.

Creator:: Kaufmann, Philip Robert
Abstract:: Tracer-derived estimates of hydraulic resistance and transient hydraulic storage were related to measures of pool volume and channel morphometric variability in small streams of the Oregon coast, U.S.A. Fourteen 100 m study reaches in 3 streams were selected to compare channel and hydraulic characteristics in streams representing a time series...

Management of the red sea urchin fishery : a biological approach

Creator:: Ubeda, Armando J.
Abstract:: The red sea urchin, Strongylocentrotus franciscanus, is one of the three species of strongylocentroids found on the west coast of North America between Baja California and Kodiak, Alaska. It belongs to the phylum Echinodermata, and it is one of the largest species of sea urchins. Since 1970, red sea urchins...

Tags Versus Genetics : Identifying Which Tool Provides the Best Information about Chinook Salmon (Oncorhynchus tshawytscha) Distributions in the California Current

Creator:: Flaherty, Ryan James
Abstract:: The movement of Chinook salmon through space and time, across political boundaries, and through fisheries, creates one of the most complex marine resource management problems in the world. Information garnered from the recovery of coded-wire tags (CWTs) has been used since the 1970s to direct management decisions. Growing concern surrounding...

Extraction and production of n-3 polyunsaturated fatty acid concentrate from Pacific sardines (Sardinops sagax)

Creator:: Okada, Tomoko
Abstract:: Intrinsic characteristics of Pacific sardines were determined. The lipid content in sardines was initially low (6.79%) in the beginning ofthe season, increased to 22.95% in mid-August, and decreased slightly by the end of September. An inverse correlation (R² = -0.90) was found between lipid and moisture content. Analysis showed that...

Synecological features of a natural headland prairie on the Oregon coast

Creator:: Davidson, Eric Duncan
Abstract:: The study of the vegetation of one of the natural coastal prairies in Oregon was undertaken for the purpose of describing some of its synecological features. Specific objectives of the study were to describe certain plant assemblages in the study area, present phenological relationships on some of the assemblages, and...
