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...

Abundance, movements, and feeding habits of harbor seals, Phoca vitulina, at Netarts and Tillamook Bays, Oregon

Creator:

Brown, Robin F. and Mate, Bruce R.

Abstract:

Patterns of seasonal abundance of harbor seals at Netarts and Tillamook Bays, Oregon, were documented by recording numbers of seals hauling out on tidally exposed sand flats in both bays. Harbor seal abundance at Tillamook Bay peaked during pupping (May-June) and molting (August) periods, while peak abundance at Netarts Bay...

Ocean distribution of the American shad (Alosa sapidissima) along the Pacific coast of North America

Creator:

Pearcy, William G. and Fisher, Joseph P.

Abstract:

We examined the incidental catches of American shad (Alosa sapidissima) taken during research cruises and in commercial and recreational landings along the Pacific coast of North America during over 30 years of sampling. Shad, an introduced species, was mainly found over the shallow continental shelf, and largest catches and highest...

Multivariate Models of Adult Pacific Salmon Returns

Creator:

Burke, Brian J., Peterson, William T., Beckman, Brian R., Morgan, Cheryl, Daly, Elizabeth A., and Litz, Marisa

Abstract:

Most modeling and statistical approaches encourage simplicity, yet ecological processes are often complex, as they are influenced by numerous dynamic environmental and biological factors. Pacific salmon abundance has been highly variable over the last few decades and most forecasting models have proven inadequate, primarily because of a lack of understanding...

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....

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...

A comparison of the survival and migratory behavior of hatchery-reared and naturally reared steelhead smolts in the Alsea River and estuary, Oregon, using acoustic telemetry

Creator:

Johnson, Steven L., Power, James Harry, Wilson, Derek R., and Ray, James

Abstract:

We tracked three groups of steelhead Oncorhynchus mykiss smolts implanted with acoustic transmitters to determine whether the degree of hatchery domestication or the juvenile rearing environment (hatchery raceway versus natural stream) influenced migration timing and survival in the Alsea River and estuary, Oregon. Two groups consisted of age-1 smolts reared...

Describing juvenile American shad and striped bass habitat use in the Hudson River Estuary using species distribution models

Creator:

O’Connor, Megan P., Juanes, Francis, McGarigal, Kevin, and Caris, Jon

Abstract:

Species distribution models (SDMs) are currently being used to identify essential fish habitat and guide fisheries management worldwide. We present SDMs based on generalized linear mixed models (GLMM) of the fall distribution or occurrence of juvenile American shad (Alosa sapidissima) and juvenile striped bass (Morone saxatilis) in the Hudson River...

Evidence that summer jellyfish blooms impact Pacific Northwest salmon production

Creator:

Ruzicka, James J., Daly, Elizabeth A., and Brodeur, Richard D.

Abstract:

Interannual variability in salmon (Oncorhynchus spp.) production in the northeast Pacific is understood to be driven by oceanographic variability and bottom-up processes affecting prey availability to juvenile salmon. Scyphozoan jellyfish have an important role in shaping the pathways of energy flow through pelagic food webs. While jellyfish obtain high production...

Salinity adaptation of the invasive New Zealand mud snail (Potamopyrgus antipodarum) in the Columbia River estuary (Pacific Northwest, USA): physiological and molecular studies

Creator:

Hoy, Marshal, Boese, Bruce L., Taylor, Louise, Reusser, Deborah, and Rodriguez, Rusty

Abstract:

In this study, we examine salinity stress tolerances of two populations of the invasive species New Zealand mud snail Potamopyrgus antipodarum, one population from a high salinity environment in the Columbia River estuary and the other from a fresh water lake. In 1996, New Zealand mud snails were discovered in...
