Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics

Creator:: Johansson, Mattias L., Litz, Marisa N. C., Brodeur, Richard D., Britt, Tristan A., Vanegas, Camilo A., Hyde, John R., and Banks, Michael A.
Abstract:: Cytochrome B sequence data (FASTA format) from the paper “Seasonal distribution and environmental associations among late larval and juvenile rockfish (Sebastes spp.) off Oregon and Washington: new insights based on genetics”. The data was generated from a sample of 2534 unknown, field collected late-larval and juvenile rockfishes from the Pacific...

Prey dominance shapes trophic structure of the northern California Current pelagic food web: evidence from stable isotopes and diet analysis

Creator:: Miller, Todd W., Brodeur, Richard D., Rau, Greg, and Omori, Koji
Abstract:: Eastern boundary current (EBC) upwelling zones are among the most productive of marine ecosystems globally and have been generalized in terms of their food web structure. Little empirically based evidence exists to suggest that there is any one form of trophic control of EBC systems and, because of logistical constraints,...

Columbia River plume fronts. II. Distribution, abundance, and feeding ecology of juvenile salmon

Creator:: De Robertis, Alex, Morgan, Cheryl A., Schabetsberger, Robert A., Zabel, Richard W., Brodeur, Richard D., Emmett, Robert L., Knight, Carolyn M., Krutzikowsky, Gregory K., and Casillas, Edmundo
Abstract:: Well-defined fronts develop at the seaward edge of riverine plumes where suspended materials and planktonic organisms are concentrated by convergent water flows. Riverine plume fronts have been hypothesized to be favorable fish habitats because they can lead to localized prey aggregations. We examined the spatial distribution of juvenile Pacific salmonids...

The Gill Pathogen Dermocystidium salmonis in Oregon Salmonids

Creator:: Olson, Robert E. and Holt, Richard A.
Abstract:: Intense infections of the gill pathogen Dermocystidium salmonis were associated with mortality of prespawning chinook salmon Oncorhynchus tshawytscha in several Oregon rivers in 1988. The occurrence of the pathogen in returning adult chinook salmon was monitored in several coastal Oregon stocks from 1989 to 1993. Although the prevalence of the...

Distribution and community structure of ichthyoplankton off the coast of Oregon, USA, in 2000 and 2002

Creator:: Auth, Toby D. and Brodeur, Richard D.
Abstract:: The species composition, distribution and concentration of ichthyoplankton off the central Oregon coast in the NE Pacific Ocean were examined during 2000 and 2002 to investigate annual, seasonal, vertical, and cross-shelf variability. Larval concentrations were also analyzed in relation to water temperature and salinity. The 281 samples collected from 5...

Influence of Regional Oceanography on the Distributions, Trophic Interactions, Growth, and Survival of the Early Life History Stages of Fishes

Creator:: Swieca, Kelsey
Abstract:: Most marine fishes experience high rates of mortality during their early life history stages with far reaching consequences for adult population dynamics. Within a few weeks of hatching, relatively small changes in larval growth and mortality rates can lead to orders of magnitude variability in year-class strength. Growth and survival...

Benthic macrofauna, sediment and water quality near seafood cannery outfalls in Yaquina Bay, Oregon

Creator:: Swartz, Richard Carlyle, 1943-, Schults, Donald W., DeBen, Waldemar A., Cole, Faith A., Oregon State University. Marine Science Center. Marine and Freshwater Ecology Branch, and Corvallis Environmental Research Laboratory
Abstract:: "Seafood canneries in lower Yaquina Ray, Oregon process shrimp (Pandalus jordani), Dungeness crab (Cancer magister), a variety of bottom fish and several salmon species. The shrimp wastes are screened and discharged directly into the Ray beneath the cannery docks. During the shrimp processing season about 3.8 million liters of wastes...

Ontogenetic shifts in diets of juvenile and subadult coho and chinook salmon in coastal marine waters: important for marine survival?

Creator:: Daly, Elizabeth A., Brodeur, Richard D., and Weitkamp, Laurie A.
Abstract:: Successfully shifting to a more piscivorous diet may be an important factor in the growth and survival of juvenile coho salmon Oncorhynchus kisutch and Chinook salmon O. tshawytscha during their first summer in the northern California Current. Nonmetric multidimensional scaling and cluster analysis of diets by size showed several distinct...
