Growth and behavioral responses to elevated temperatures by juvenile sablefish Anoplopoma fimbria and the interactive role of food availability

Creator:: Sogard, Susan M. and Olla, Bori L.
Abstract:: Larval and age-0 sablefish Anoplopoma fimbria reside in neustonic waters of the North Pacific during spring and summer. We estimated the potential impacts of elevated surface temperatures on ecological processes of growth, conversion efficiency, and behavior in early juvenile sablefish. Growth experiments tested a wide range of temperatures from 6...

Behavior of juvenile bluefish Pomatomus saltatrix in vertical thermal gradients: influence of season, temperature acclimation and food

Creator:: Olla, Bori L., Studholme, Anne L., and Bejda, Allen J.
Abstract:: Behavioral responses of juvenile bluefish P. saltatrix L. exposed to cold water in a vertical thermal gradient were measured under controlled laboratory conditions. The temperature regime was similar to conditions that these fish encounter in their inshore and estuarine habitats along the Middle Atlantic coast. Measures included activity, schooling, position...

Effects of physical gradients on the production dynamics of sediment-associated algae

Creator:: Davis, Michael W. and McIntire, C. David
Abstract:: Sediment-associated microalgal biomass expressed as chlorophyll a concentration, total organic matter concentration expressed as ash-free dry weight, and hourly rates of net community primary production and community oxygen consumption were measured at monthly intervales at medium sand, fine sand, and silt sites between 0.5 and 2.0 m above MLLW during...

Effects of the 1997-1998 El Niño on early-juvenile Pacific hake Merluccius productus: age, growth, abundance, and diet in coastal nursery habitats

Creator:: Grover, Jill J., Buckley, Troy W., and Woodbury, David
Abstract:: The effects of anomalous oceanographic conditions on growth, abundance, spawn-date distributions, and diet of early-juvenile Pacific hake Merluccius productus were examined in nursery grounds off the coast of central California, USA. Spring collections from 2 consecutive years of El Nino conditions, 1997 and 1998, 1 year of La Nina conditions,...

The relationships between predatory fish, forage fishes, and juvenile salmonid marine survival off the Columbia River: a simple trophic model analysis

Creator:: Emmett, Robert L. and Sampson, David B.
Abstract:: A trophic model that simulates interactions between a predatory fish (Pacific hake, Merluccius productus), forage fish, and juvenile salmon off the Columbia River was constructed to identify if trophic interactions could account for marine mortality of Columbia River juvenile salmon. The model estimates the number of juvenile salmon that are...

Tsunami Evacuation Plan for the Hatfield Marine Science Center - Newport, OR

Creator:: Hunter-Zaworski, Katherine and Intelligent Transportation Systems Class
Abstract:: This report outlines the current evacuation plan for Oregon State University's Hatfield Marine Science Center and makes recommendations for enhancements and changes. The physical setting is described along with detail on evacuation strategies. Recommendations include reducing personnel working on the South Beach Peninsula, improving current evacuation point, improving communication and...

History of the Oregon State University's Hatfield Marine Science Center. Volume II, 1988-2001

Creator:: Rogers, Pamela A.
Abstract:: "The MSC was created through the impetus of three needs. Wayne Burt of the newly formed Oceanography Department needed dock and ship support facilities for his NSF-funded research vessel on the coast. Roland Dimick of the Fisheries and Wildlife Department needed to expand his small bay research lab located at...

Skin Deep: An Assessment of New Zealand Blue Whale Skin Condition

Creator:: Barlow, Dawn R., Pepper, Acacia L., and Torres, Leigh G.
Abstract:: Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...

Uncertainty and Precautionary Management of Marine Fisheries: Can the Old Methods Fit the New Mandates?

Creator:: Weeks, Hal and Berkeley, Steve
Abstract:: Continued stock declines in marine fisheries have resulted in a search for more risk-averse management approaches. In response, the Sustainable Fisheries Act of 1996 mandates habitat protection, bs catch reduction, and stock rebuilding. These changes emphasize precaution, and imply a shift in focus from maximizing yields to minimizing ecological impacts...
