Ontogenetic patterns and temperature-dependent growth rates in early life stages of Pacific cod (Gadus macrocephalus)

Creator:: Hurst, Thomas P., Laurel, Benjamin J., and Ciannelli, Lorenzo
Abstract:: Pacific cod (Gadus macrocephalus)is an important component of fisheries and food webs in the North Pacific Ocean and Bering Sea. However, vital rates of early life stages of this species have yet to be described in detail. We determined the thermal sensitivity of growth rates of embryos, pref lexion and...

Albacore oceanography off Oregon : 1970

Creator:: Pearcy, William G.
Abstract:: During July 1970, albacore boats trolling surface jigs (jig boats) had record catches in an area off the mouth of the Columbia River. The jig fishery declined suddenly in late July and was poor throughout the remainder of the summer. No obvious oceanographic changes were correlated with these drastic changes...

Integration of submersible transect data and high-resolution multibeam sonar imagery for a habitat-based groundfish assessment of Heceta Bank, Oregon

Creator:: Nasby-Lucas, Nicole M., Embley, Bob W., Hixon, Mark A., Merle, Susan G., Tissot, Brian N., and Wright, Dawn J.
Abstract:: In the face of dramatic declines in groundfish populations and a lack of sufficient stock assessment information, a need has arisen for new methods of assessing groundfish populations. We describe the integration of seafloor transect data gathered by a manned submersible with high-resolution sonar imagery to produce a habitat- based...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...

Seasonal and interannual variation in juvenile salmonids and associated fish assemblage in open waters of the lower Columbia River estuary

Creator:: Weitkamp, Laurie A., Bentley, Paul J., and Litz, Marisa N. C.
Abstract:: The transition between freshwater and marine environments is associated with high mortality for juvenile anadromous salmonids, yet little is known about this critical period in many large rivers. To address this deficiency, we investigated the estuarine ecology of juvenile salmonids and their associated fish assemblage in open-water habitats of the...

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...

Seasonal changes in growth of coho salmon (Oncorhynchus kisutch) off Oregon and Washington and concurrent changes in the spacing of scale circuli

Creator:: Fisher, Joseph P. and Pearcy, William G.
Abstract:: In this study we present new information on seasonal variation in absolute growth rate in length of coho salmon (Oncorhynchus kisutch) in the ocean off Oregon and Washington, and relate these changes in growth rate to concurrent changes in the spacing of scale circuli. Average spacing of scale circuli and...

In cold blood: evidence of Pacific sleeper shark (Somniosus pacificus) predation on Steller sea lions (Eumetopias jubatus) in the Gulf of Alaska

Creator:: Horning, Markus and Mellish, Jo-Ann E.
Abstract:: Temperature data received post mortem in 2008–13 from 15 of 36 juvenile Steller sea lions (Eumetopias jubatus) that had been surgically implanted in 2005–11 with dual life history transmitters (LHX tags) indicated that all 15 animals died by predation. In 3 of those 15 cases, at least 1 of the...

A new species of Sebastes (Scorpaeniformes: Sebastidae) from the northeastern Pacific, with a redescription of the blue rockfish, S. mystinus (Jordan and Gilbert, 1881)

Creator:: Frable, Benjamin W., Wagman, D. Wolfe, Frierson, Taylor N., Aguilar, Andres, and Sidlauskas, Brian L.
Abstract:: The diverse predatory rockfishes (Sebastes spp.) support extensive commercial fisheries in the northeastern Pacific. Although 106 species of Sebastes are considered valid, many of the ecological, geographical, and morphological boundaries separating them lack clarity. We clarify one such boundary by separating the blue rockfish Sebastes mystinus (Jordan and Gilbert, 1881)...

Creator:: Brown, Stephen K., Shivlani, Manoj, Die, David, Sampson, David B., and Ting, Tina A.
Abstract:: Requirements are growing for peer review of the science used for governmental management decisions. This is particularly true for fisheries science, where management decisions are often controversial. The National Oceanic and Atmospheric Administration's National Marine Fisheries Service instituted the Center for Independent Experts (CIE) in 1998 as a national peer-review...
