Professional Development Training in Ocean Acidification: A Case Study of Marine Resource Managers

Creator:: Moses, Michael L.
Abstract:: Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...

Comparison of growth, behavior and lipid concentrations of walleye pollock Theragra chalcogramma larvae fed lipid-enriched, lipid-deficient and field-collected prey

Creator:: Davis, Michael W. and Olla, Bori L.
Abstract:: While growth and survival of marine fish larvae in the sea may be dependent on prey type, size and concentration, nutritional quality of prey may also play an important role. This study investigates the relationships of lipid content of prey with growth, gas bladder size, sinking rate, behavior and survival...

Effects of physical factors on the vertical distribution of larval walleye pollock Theragra chalcogramma under controlled laboratory conditions

Creator:: Olla, Bori L. and Davis, Michael W.
Abstract:: This study examined, under controlled laboratory conditions, behavioral responses of larval walleye pollock (4 to 8 mm) to various physical factors that may potentially play a role in vertical movements and distribution. Diel periodicity in vertical distribution was evident and appeared to be under exogenous control. During the day, with...

Stress and delayed mortality induced in Pacific halibut by exposure to hooking, net towing, elevated seawater temperature and air: implications for management of bycatch

Creator:: Davis, Michael W. and Olla, Bori L.
Abstract:: The extent of stress and eventual mortality in Pacific halibut Hippoglossus stenolepis that resulted from simulated capture by hooking or towing in a net, followed by abrupt exposure to warmer seawater temperature and air, were determined under laboratory conditions. Abrupt exposure to 16degreesC seawater and air after either method of...

Mortality of Lingcod Towed in a Net as Related to Fish Length, Seawater Temperature, and Air Exposure: A Laboratory Bycatch Study

Creator:: Davis, Michael W. and Olla, Bori L.
Abstract:: The mortality of discarded bycatch is a critical problem in the management of fisheries worldwide. Little is known about the key principles involved in the mortality of discarded bycatch. These principles are best elaborated under controlled conditions in the laboratory where the actions and interactions of stressors found in fishing...

Comparison of Predator Avoidance Capabilities with Corticosteroid Levels Induced by Stress in Juvenile Coho Salmon

Creator:: Olla, Bori L., Davis, Michael W., and Schreck, Carl B.
Abstract:: The relationship between predator avoidance deficits induced by a simple handling stress and the level of plasma corticosteroids was determined for juvenile coho salmon Oncorhynchus kisutch. Groups of fish were held out of water for 1 min, then allowed to recover from this stress for 1, 90, or 240 min....

The mitochondrial genomes of Euphausia pacifica and Thysanoessa raschii sequenced using 454 next-generation sequencing, with a phylogenetic analysis of their position in the Malacostracan family tree

Creator:: Johansson, Mattias L., Sremba, Angela L., Feinberg, Leah R., Banks, Michael A., and Peterson, William T.
Abstract:: Euphausiid krill play a critical role in coastal and oceanic food webs, linking primary producers to upper trophic levels. In addition, some species support commercial fisheries worldwide. Despite their ecological importance, the genetics of these important species remain poorly described. To improve our understanding of the genetics of these ecological...

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...

Capture-Related Stressors Impair Immune System Function in Sablefish

Creator:: Lupes, Sarah C., Davis, Michael W., Olla, Bori L., and Schreck, Carl B.
Abstract:: The sablefish Anoplopoma fimbria is a valuable North Pacific Ocean species that, when not targeted in various commercial fisheries, is often a part of discarded bycatch. Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the...

Characterization of the physiological stress response in lingcod

Creator:: Milston, Ruth H., Davis, Michael W., Parker, Steven J., Olla, Bori L., Clements, Shaun, and Schreck, Carl B.
Abstract:: The goal of this study was to describe the duration and magnitude of the physiological stress response in lingcod Ophiodon elongatus after exposure to brief handling and sublethal air stressors. The response to these stressors was determined during a 24‐h recovery period by measuring concentrations of plasma cortisol, lactate, glucose,...
