Recent pre-recruit Pacific hake (Merluccius productus) occurrences in the Northern California Current suggest a northward expansion of their spawning area

Creator:: Phillips, A. Jason, Ralston, Stephen, Brodeur, Richard D., Auth, Toby D., Emmett, Robert L., Johnson, Carrie, and Wespestad, Vidar G.
Abstract:: Coastal Pacific hake (Merluccius productus) are known to spawn in the southern California Bight from January to March, migrate north during late spring and summer to feed off Oregon, Washington, and British Columbia, and then move back to southern California in the fall. Juvenile Pacific hake nursery areas have been...

Feeding habits of northern fur seals (Callorhinus ursinus) in the eastern Bering Sea

Creator:: Sinclair, Elizabeth
Abstract:: This study was conducted to determine the composition and size of prey consumed by northern fur seals (Callorhinus ursinus) in the eastern Bering Sea. Eighty three northern fur seals were collected in the summer and fall of 1981, 1982, and 1985 for examination of gastrointestinal contents. A total of 139...

A methodology for evaluating the economic impact on directed fisheries of by-catch losses in the foreign and joint-venture groundfish fisheries

Creator:: Queirolo, Lewis E.
Abstract:: The principal objective of this analysis is the development of a methodological approach that would permit a more complete evaluation of the physical and economic consequences of prohibited species by-catch (PSC) losses, such as occur in the harvest of groundfish. To achieve efficient management of the several marine species involved...

Seasonal distribution and environment of adult Pacific herring (Clupea harengus pallasi) near Auke Bay, Lynn Canal, southeastern Alaska

Creator:: Carlson, Harry Richard
Abstract:: The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a...

Life-history organization of herring (Clupea harengus pallasi) in the northeast Pacific

Creator:: Aleaziz, Farzad
Abstract:: The distribution of herring (Clupea harengus pallasi) in the Northeast Pacific extends from southern California to northern Alaska. Studies on variation in herring life-history are limited to local characteristics and recruitment populations or relatively restricted regions of the Northeast Pacific. In this study I assessed herring life-history patterns and recruitment...

Effects of seasonal and interannual variability in along-shelf and cross-shelf transport on groundfish recruitment in the eastern Bering Sea

Creator:: Vestfals, Cathleen D., Ciannelli, Lorenzo, Duffy-Anderson, Janet T., and Ladd, Carol
Abstract:: The Bering Sea responds rapidly to atmospheric perturbations and over the past several decades has experienced extreme variability in both its physical and biological characteristics. These changes can impact organisms that inhabit the region, particularly marine fishes, as normal current patterns to which reproductive habits are tuned can be disrupted,...

Implementation of radiation film dosimetry system to be used for the verification of a 3-D electron pencil-beam algorithm on a radiation treatment planning system

Creator:: Jones, Quyen L.
Abstract:: Radiation film dosimetry process using the RIT 113 v.4 dosimetry software and the film digitizer VXR-l2plus was used to evaluate the accuracy of electron dose calculations of the RAHD radiation therapy treatment planning system at Samaritan Regional Cancer Center. Kodak Ready-Pack EDR-2 film is recommended for dose distribution analysis in...

Creator:: Pérez-Pérez, Marcos, Garza-Gil, Dolores, Varela-Lafuente, Manuel, and Surís-Regueiro, Juan
Abstract:: The aim of this work is to develop a predator-prey model for two species of commercial importance captured by the European fishing fleet in the European Grounds. In this model, the hake (Merluccius merluccius) represents the predator, and the blue whiting (Micromesistius poutassou) is the prey. Both the predator and...

Do walleye pollock exhibit flexibility in where or when they spawn based on variability in water temperature?

Creator:: Bacheler, Nathan M., Ciannelli, Lorenzo, Bailey, Kevin Mclean, and Bartolino, Valerio
Abstract:: Environmental variability is increasingly recognized as a primary determinant of year-class strength of marine fishes by directly or indirectly influencing egg and larval development, growth, and survival. Here we examined the role of annual water temperature variability in determining when and where walleye pollock (Theragra chalcogramma) spawn in the eastern...
