Estimating minke whale (Balaenoptera acutorostrata) boing sound density using passive acoustic sensors

Creator:: Martin, Stephen W., Marques, Tiago A., Thomas, Len, Morrissey, Ronald P., DiMarzio, Nancy, Moretti, David, Mellinger, David K., and Jarvis, Susan
Abstract:: Density estimation for marine mammal species is performed primarily using visual distance sampling or capture-recapture. Minke whales in Hawaiian waters are very difficult to sight; however, they produce a distinctive “boing” call, making them ideal candidates for passive acoustic density estimation. We used an array of 14 bottom-mounted hydrophones, distributed...

Marine distributions of chinook salmon from the West Coast of North America determined by coded wire tag recoveries

Creator:: Weitkamp, Laurie A.
Abstract:: The coded wire tag (CWT) database contains detailed information on millions of Pacific salmon Oncorhynchus spp. released from hatcheries or smolt traps and recovered in the north Pacific Ocean and its tributaries. I used this data set to examine the spatial and temporal variation in the marine distributions of 77...

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...

Microsatellites Reveal Population Identity of Individual Pink Salmon to Allow Supportive Breeding of a Population at Risk of Extinction

Creator:: Olsen, Jeffrey B., Bentzen, Paul, Banks, Michael A., Shaklee, James B., and Young, Sewall
Abstract:: Efforts to restore depressed populations of Pacific salmon Oncorhynchus spp. are often hampered by the inability to assign population identity to individuals in an admixture. This knowledge is of particular concern in supportive breeding programs, in which misidentification of individuals to population may result in progeny of mixed heritage, which,...

Diel Feeding Chronology, Gastric Evacuation, and Daily Food Consumption of Juvenile Chinook Salmon in Oregon Coastal Waters

Creator:: Benkwitt, Cassandra E., Brodeur, Richard D., Hurst, Thomas P., and Daly, Elizabeth A.
Abstract:: The diel feeding periodicity of juvenile Chinook salmon Oncorhynchus tshawytscha was determined from stomachs collected in coastal waters off Oregon in 2000 and 2003. Juvenile Chinook salmon exhibited a diurnal feeding pattern with morning and evening feeding periods. There were differences in the duration and magnitude of the dawn and...

Submarine landslide triggered by volcanic eruption recorded by in situ hydrophone

Creator:: Chadwick, W.W. Jr., Dziak, R.P., Haxel, J.H., Embley, R.W., and Matsumoto, H.
Abstract:: NW Rota-1 is a submarine volcano in the Mariana volcanic arc that is notable as the site where underwater explosive eruptions were first witnessed in A. D. 2004. After years of continuous low-level eruptive activity, a major landslide occurred at NW Rota-1 in August 2009, triggered by an unusually large...

Comparison of submersible-survey and hydroacoustic-survey estimates of fish density on a rocky bank

Creator:: Starr, Richard M., Fox, David S., Hixon, Mark Anthony, Tissot, Brian N., Johnson, Gary E., and Barss, William H.
Abstract:: Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...

Behavior of Nine Species of Pacific Rockfish after Hook-and-Line Capture, Recompression, and Release

Creator:: Hannah, Robert W. and Matteson, Keith M.
Abstract:: We evaluated the effect of barotrauma on the behavior of nine species of Pacific rockfish Sebastes spp. after hook-and-line capture and release using a video-equipped underwater release cage. Sampling was conducted across a range of bottom depths (12-194 m), mostly where barotrauma resulting from an expanded swim bladder and gaseous...

Ocean habitat use in autumn by Chinook salmon in coastal waters of Oregon and California

Creator:: Hinke, Jefferson T., Watters, George M., Boehlert, George W., and Zedonis, Paul
Abstract:: Describing the ocean habitats used by Chinook salmon Oncorhynchus tshawytscha is an important step towards understanding how environmental conditions influence their population dynamics. We used data from archival tags that recorded time, temperature and pressure (depth) to define the coastal habitats used by Chinook near Oregon and California during the...

Elemental Markers in Elasmobranchs: Effects of Environmental History and Growth on Vertebral Chemistry

Creator:: Smith, Wade D., Miller, Jessica A., and Heppell, Selina S.
Abstract:: Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...
