Interannual Variation in Diet and Condition in Juvenile Bluefish during Estuarine Residency

Creator:: Friedland, K. D., Garman, G. C., Bejda, A. J., Studholme, A. L., and Olla, B. L.
Abstract:: We examined the diets and weight-length relationships of juvenile bluefish Pomatomus saltatrix from Sandy Hook Bay, New Jersey, during 1981, 1983, and 1984. Diets consisted of a variety of polychaete, crustacean, and fish prey. Opossum shrimp Neomysis americana. sand shrimp Crangon septemspinosa, grass shrimp Palaemonetes vulgar is, bay anchovy Anchoa...

Altered search speed and growth: social versus independent foraging in two pelagic juvenile fishes

Creator:: Ryer, Clifford H. and Olla, Bori L.
Abstract:: Prior studies have demonstrated that juvenile walleye pollock Theragra chalcogramma forage socially in schools for spatially and temporally clumped food, but forage more independently for spatially and temporally dispersed food. One advantage of social foraging is that fish in schools may be able to locate more food clumps than fish...

Research, Monitoring, and Evaluation of Fish and Wildlife Restoration Projects in the Columbia River Basin: Lessons Learned and Suggestions for Large- Scale Monitoring Programs

Creator:: McDonald, Lyman L., Bilby, Robert, Bisson, Peter A., Coutant, Charles C., Epifanio, John M., Goodman, Daniel, Hanna, Susan S., Huntly, Nancy, Merrill, Erik, Riddell, Brian, Liss, William, Loudenslager, Eric J., Philipp, David P., Smoker, William, Whitney, Richard R., and Williams, Richard N.
Abstract:: El ano 2006 representa en dos sentidos una fecha critica para la cuenca del Rio Columbia y para los esfuerzos de recuperacion del salmon y la trucha arcoiris en la region Pacifico Noroeste: el 25 aniversario de la creacion del Consejo para la Conservacion y Poder del Noroeste y el...

Relationship between oceanic mesozooplankton and energy of eddy fields

Creator:: Piontkovski, S. A., Williams, R., Peterson, William T., and Kosnirev, V. K.
Abstract:: The impact of mesoscale eddies on the spatial distribution of zooplankton biomass was analysed using data from the Arabian Sea and the Black Sea. The highest values of spatial variance of zooplankton biomass in the upper 100 to 150 m were found in regions with maximum available potential energy of...

A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales

Creator:: Villegas-Amtmann, S., Schwarz, L. K., Sumich, J. L., and Costa, D. P.
Abstract:: While sophisticated tools are used to monitor behavioral changes of large marine vertebrates, determining whether these changes are meaningful for management and conservation is challenging. The Population Consequences of Disturbance model proposed a bioenergetics model to detect biologically meaningful population responses, where disturbance costs are linked to lost energy. The...

Man in the marine environment

Creator:: Hogg, Thomas C., Smith, Courtland L., and Davis, Wilbur A.
Abstract:: This report has three primary objectives; it attempts to examine the relationship of various cultural systems to the marine environment, seeks to create an inventory of uses man has put the marine environment to, and makes an analysis of the attitudes of people towards the marine environment.

An Evaluation of the Influence of Stock Origin and Outmigration History on the Disease Susceptibility and Survival of Juvenile Chinook Salmon

Creator:: Dietrich, Joseph P., Boylen, Deborah A., Thompson, Donald E., Loboschefsky, Erik J., Bravo, Claudia F., Spangenberg, Dina K., Ylitalo, Gina M., Collier, Tracy K., Fryer, Derek S., Arkoosh, Mary R., and Loge, Frank J.
Abstract:: Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may...

Hydrothermal Discharge During Submarine Eruptions

Creator:: Baker, Edward T., Chadwick, Wi l l iam W. Jr., Cowen, James P., Dziak, Robert P., Rubin, Kenneth H., and Fornari, Daniel J.
Abstract:: Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to the ocean, but the processes that control these transfers are poorly...

Jellyfish, Forage Fish, and the World’s Major Fisheries

Creator:: Robinson, Kelly L., Ruzicka, James J., Decker, Mary Beth, Brodeur, Richard D., Hernandez, Frank J., Quiñones, Javier, Acha, E. Marcelo, Uye, Shin-ichi, Mianzan, Hermes, and Graham, William M.
Abstract:: A majority of the world’s largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap...

Post-Breeding Season Migrations of a Top Predator, the Harbor Seal (Phoca vitulina richardii), from a Marine Protected Area in Alaska

Creator:: Womble, Jamie N. and Gende, Scott M.
Abstract:: Marine protected areas (MPAs) are increasingly being used as a conservation tool for highly mobile marine vertebrates and the focus is typically on protecting breeding areas where individuals are aggregated seasonally. Yet movements during the non-breeding season can overlap with threats that may be equally as important to population dynamics....
