A comparison of the survival and migratory behavior of hatchery-reared and naturally reared steelhead smolts in the Alsea River and estuary, Oregon, using acoustic telemetry

Creator:: Johnson, Steven L., Power, James Harry, Wilson, Derek R., and Ray, James
Abstract:: We tracked three groups of steelhead Oncorhynchus mykiss smolts implanted with acoustic transmitters to determine whether the degree of hatchery domestication or the juvenile rearing environment (hatchery raceway versus natural stream) influenced migration timing and survival in the Alsea River and estuary, Oregon. Two groups consisted of age-1 smolts reared...

Microsatellites Reveal Population Identity of Individual Pink Salmon to Allow Supportive Breeding of a Population at Risk of Extinction

Creator:: Olsen, Jeffrey B., Bentzen, Paul, Banks, Michael A., Shaklee, James B., and Young, Sewall
Abstract:: Efforts to restore depressed populations of Pacific salmon Oncorhynchus spp. are often hampered by the inability to assign population identity to individuals in an admixture. This knowledge is of particular concern in supportive breeding programs, in which misidentification of individuals to population may result in progeny of mixed heritage, which,...

Dividing up the pie: Whales, fish, and humans as competitors

Creator:: Ruzicka, James J., Steele, John H., Ballerini, Tosca, Gaichas, Sarah K., and Ainley, David G.
Abstract:: Similarly structured food web models of four coastal ecosystems (Northern California Current, Central Gulf of Alaska, Georges Bank, southwestern Antarctic Peninsula) were used to investigate competition among whales, fishes, pinnipeds, and humans. Two analysis strategies simulated the effects of historic baleen and odontocete whale abundances across all trophic levels: food...

Beached birds and physical forcing in the California Current System

Creator:: Parrish, Julia K., Bond, Nicholas, Nevins, Hannah, Mantua, Nathan, Loeffel, Robert, Peterson, William T., and Harvey, James T.
Abstract:: Seabirds have often been proposed as environmental indicators. Beached bird data may provide an additional data source and such data is efficacious because it can reliably be collected by volunteers. In addition to anthropogenic factors, such as oil spills, changes in the ocean-atmosphere can affect carcass beaching rate in 3...

Gear-Related Mortality in Selective Fisheries for Ocean Salmon

Creator:: Lawson, Peter W. and Sampson, David B.
Abstract:: In ocean fisheries for Pacific salmon Oncorhynchus spp., there can be several forms of gear-related mortality. Much research effort has been directed at estimating mortality rates for salmon that are hooked and then released. Also potentially important but not easily measured is mortality of fish that escape from the hook...

A study of the effects of a wave gradient on intertidal zonation at Yaquina Head, Lincoln County, Oregon

Creator:: Davis, Michael W., Arana, Patricio, Reid, James, and Schrock, Richard
Abstract:: This is a student report which studies the effects of wave action on intertidal zonation at Yaquina Head. It includes hand-drawn diagrams of quadrants sampled at the location.

The response to forced decompression in six species of Pacific rockfish

Creator:: Pribyl, Alena L., Kent, Michael L., Parker, Steven J., and Schreck, Carl B.
Abstract:: Pacific rockfish experience high discard mortality when captured owing to a condition called barotrauma,which is caused by the change in pressure during capture. This condition appears to be species specific at the macroscopic level; however, little is known about the microscopic tissue-level effects of barotrauma. Determining whether tissue-level injuries are...

Biological indicators of the timing and direction of warm-water advection during the 1997/1998 El Niño off the central Oregon coast, USA

Creator:: Keister, Julie E., Johnson, Travis B., Morgan, Cheryl A., and Peterson, William T.
Abstract:: Unusual collections of several euphausiid, chaetognath, and copepod species help elucidate the effects of the strong 1997/1998 El Niño off the central Oregon, USA, coast. Furcilia of Nyctiphanes simplex, a euphausiid typically found only as far north as central California, were collected in bi-weekly nearshore samples between December 1997 and...

Predator and shelter-size effects on coral reef fish and spiny lobster prey

Creator:: Eggleston, David B., Lipcius, Romuald N., and Grover, Jill J.
Abstract:: Population dynamics of coral reef fishes and spiny lobster appear to be determined by variable recruitment interacting with post-settlement processes, particularly predation. The risk of predation may be modified by the scaling between prey and shelter size, which enhances the protective capacity of a reef. We experimentally tested these predictions...
