Spatial and trophic overlap of marked and unmarked Columbia River Basin spring Chinook salmon during early marine residence with implications for competition between hatchery and naturally produced fish

Creator:

Daly, Elizabeth A., Brodeur, Richard D., Fisher, Joseph P., Weitkamp, Laurie A., Teel, David J., and Beckman, Brian R.

Abstract:

Ecological interactions between natural and hatchery juvenile salmon during their early marine residence, a time of high mortality, have received little attention. These interactions may negatively influence survival and hamper the ability of natural populations to recover. We examined the spatial distributions and size differences of both marked (hatchery) and...

Attitudes of Trawl Vessel Captains about Work, Resource Use, and Fishery Management

Creator:

Hanna, Susan S. and Smith, Courtland L.

Abstract:

The fisheries literature embodies critical assumptions about fisherman attitudes and motivations. Common assumptions are that populations of fisherman are homogeneous in motivation and decision making and that they behave in a myopic fashion, ignoring the effects of their fishing activities on the fishery resource. The results of a survey of...

Increased Susceptibility of Juvenile Chinook Salmon to Vibriosis after Exposure to Chlorinated and Aromatic Compounds Found in Contaminated Urban Estuaries

Creator:

Arkoosh, Mary R., Clemons, Ethan, Huffman, Paul, Kagley, Anna N., Casillas, Edmundo, Adams, Nick, Sanborn, Herb R., Collier, Tracy K., and Stein, John E.

Abstract:

Saltwater-adapted juvenile chinook salmon Oncorhynchus tshawytscha exposed to aromatic and chlorinated compounds, representative of contaminants found in urban estuaries in Puget Sound, have a higher susceptibility to vibriosis than do fish exposed only to the solvent vehicle. Susceptibility to vibriosis was assessed by examining the percent cumulative mortality of the...

Buoyancy regulation by hatchery and wild coho salmon during the transition from freshwater to marine environments

Creator:

Weitkamp, Laurie A.

Abstract:

One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter their whole-fish density (WFD) or they will become positively (float) or negatively (sink) buoyant as they change environments....

Abstract:

The operation of the Federal Columbia River Power System (FCRPS) has negatively affected threatened and endangered salmonid populations in the Pacific Northwest. Barging Snake River spring Chinook salmon Oncorhynchus tshawytscha through the FCRPS is one effort to mitigate the effect of the hydrosystem on juvenile salmon out-migration. However, little is...

Abstract:

The bivalve Pacific geoduck (Panopea generosa) has been used in the eastern North Pacific Ocean to create proxies for environmental factors such as temperature and oceanographic conditions. This type of research depends upon accurate age determination of Pacific geoducks, which historically was based on shell growth-increment counts. A recent study...

Surface distribution of brachyuran megalopae and ichthyoplankton in the Columbia River plume during transition from downwelling to upwelling conditions

Creator:

Roegner, G. Curtis, Daly, Elizabeth A., and Brodeur, Richard D.

Abstract:

In the California Current coastal boundary zone, the spring transition between downwelling and upwelling conditions, along with the fluctuating structure of the Columbia River plume, creates highly dynamic interactions. In this study, we investigated whether the surface distribution of brachyuran larvae and ichthyoplankton would track the dynamics of the Columbia...

Interannual variability in the Northern California Current food web structure: Changes in energy flow pathways and the role of forage fish, euphausiids, and jellyfish

Creator:

Ruzicka, James J., Brodeur, Richard D., Emmett, Robert L., Steele, John H., Zamon, Jeannette E., Morgan, Cheryl A., Thomas, Andrew C., and Wainwright, Thomas C.

Abstract:

The Northern California Current (NCC) is a seasonally productive and open ecosystem. It is home to both a diverse endemic community and to seasonally transient species. Productivity and food web structure vary seasonally, interannually, and decadally due to variability in coastal upwelling, climate-scale physical processes, and the migratory species entering...

Market Information and Fisheries Management: A Multiple-Objective Analysis

Creator:

Sylvia, Gilbert

Abstract:

Market issues are often critical to the regional and national benefits that can be generated from fisheries management. In actual policy analysis, however, market considerations are often treated as exogenous to the fisheries policy problem. Examples illustrate the relationships between product characteristics, market demand, and regulatory management. A multiple-objective socioeconomic...
