The influence of bait and stereo video on the performance of a video lander as a survey tool for marine demersal reef fishes in Oregon waters

Creator:: Hannah, Robert W. and Blume, Matthew T. O.
Abstract:: We evaluated how the use of bait as a fish attractant influenced the species and size composition 20 of demersal fishes viewed with a stereo video lander, at 160 sampling sites at Stonewall Bank, a 21 deepwater rocky reef complex in Oregon waters. We also studied the effectiveness of stereo...

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...

A doubled down invasion of the northeast Pacific by the Asian mud shrimp, Upogebia major and its coevolved bopyrid isopod parasite, Orthione griffenis

Creator:: Chapman, John W., Li, Jingchun, McGowan, Michael F., Breitenstein, Ralph A., Appy, Ralph, Hieb, Kathryn A., Piotrowski, Christina N., and Elder, Leanne E.
Abstract:: Dramatic declines of the native northeast Pacific mud shrimp, Upogebia pugettensis over the last three decades have occurred in response to intense infestations by the Asian bopyrid isopod parasite, Orthione griffenis, that was introduced in the 1980s. We report herein the arrival of the Asian mud shrimp, Upogebia major, in...

Sex identification PCR–RFLP assay tested in eight species of Sebastes rockfish

Creator:: Vaux, Felix, Aycock, Hannah M., Bohn, Sandra, Rasmuson, Leif K., and O'Malley, Kathleen G.
Abstract:: The phenotypic identification of sex in Sebastes rockfish is difficult and often impractical from a management perspective, and the genetic basis of sex determination in the genus is currently uncertain. We tested a previously developed sex identifi- cation polymerase chain reaction restriction fragment length polymorphism (PCR–RFLP) assay in eight species...

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...

Site Fidelity and Movement of Eight Species of Pacific Rockfish at a High-Relief Rocky Reef on the Oregon Coast

Creator:: Hannah, Robert W. and Rankin, Polly S.
Abstract:: We used acoustic telemetry techniques to study the movements of eight species of Pacific rockfish (genus Sebastes) inhabiting Siletz Reef, a high-relief rocky reef complex on the Oregon coast. Our primary interest was evaluating potential residence times for rockfish species in small, no-take marine protected areas (MPAs) like those recently...

A Low-Volume Flow-Through System for Rearing Pacific Oyster (Crassostrea gigas) Larvae

Creator:: Fleener, Henry R.
Abstract:: Standard larval Pacific oyster (Crassostrea gigas) rearing systems can be described as either static or continuous flow. While rearing oyster larvae in static cultures can be a low-cost and simple method, static systems require significant husbandry effort, floorspace and can produce highly variable results due to environmental variance among cultures....

A latitudinal cline in the Chinook salmon (Oncorhynchus tshawytscha) Clock gene: evidence for selection on PolyQ length variants

Creator:: O'Malley, Kathleen G. and Banks, Michael A.
Abstract:: A critical seasonal event for anadromous Chinook salmon (Oncorhynchus tshawytscha) is the time at which adults migrate from the ocean to breed in freshwater. We investigated whether allelic variation at the circadian rhythm genes, OtsClock1a and OtsClock1b, underlies genetic control of migration timing among 42 populations in North America. We...

Survey of Pathogens in Hatchery Chinook Salmon with Different Out-Migration Histories through the Snake and Columbia Rivers

Creator:: Van Gaest, Ahna L., Dietrich, Joseph P., Thompson, D. E., Boylen, Deborah A., Strickland, Stacy A., Collier, T. K., Loge, F. J., and Arkoosh, Mary R.
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...
