A macroscopic to microscopic study of the effects of barotrauma and the potential for long-term survival in Pacific rockfish

Creator:: Pribyl, Alena L.
Abstract:: Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

The Genetics of Larval Fitness in the Pacific Oyster: Responses to Acidified Seawater and Temporally Dynamic Selection Processes

Creator:: Durland, Evan R.
Abstract:: The Pacific Oyster (Crassostrea gigas) is one of the most economically and ecologically significant shellfish species worldwide. In the Pacific Northwest United States (PNW), the sustainability oyster stocks is increasingly threatened by ocean acidification (OA), which has had significant negative effects on the aquaculture industry in this region over the...

A model of fall chinook salmon (Onchorhynchus tshawytscha) life history

Creator:: Hirai, Takayuki
Abstract:: The research involved development of two ecological simulation models to explain the complex dimensionality of chinook salmon (Oncorhynchus tshawytscha) life history structure (represented by the age composition of the spawning stock) and management difficulties entailed in the complexity. Since different sizes of chinook salmon are thought to adapt differently to...

Enrichment of Live Prey with Microparticles for the Enhanced Delivery of Water-soluble Nutrients to Marine Fish Larvae

Creator:: Hawkyard, Donald Matthew
Abstract:: In the wild, marine fish larvae feed on copepods and other planktonic organisms. Copepods are often considered the "gold standard" for meeting the nutritional needs of cultured marine fish larvae; however, in captivity, marine fish larvae are generally fed cultured live prey, i.e. rotifers (Brachionus plicatilis) and/or Artemia sp., until...

The physiology ecology and run diversity of adult Pacific lamprey, Entosphenus tridentatus, during the freshwater spawning migration

Creator:: Clemens, Benjamin J.
Abstract:: Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...

Improving Projections of Tidal Marsh Persistence under Climate Change with Remote Sensing and Site-Specific Data

Creator:: Buffington, Kevin J.
Abstract:: Tidal marshes are dynamic ecosystems that are threatened by climate change and sea-level rise. To characterize baseline condition and historic climate sensitivities, and improve projections into the future, new methods are required that integrate data from the field and remote sensing platforms. Marsh elevation response models can be calibrated with...

Value of Prior and Novel Information in Managing a Mixed-Stock Recreational Chinook Salmon Fishery

Creator:: Jensen, Alexander J.
Abstract:: Many economically important Pacific salmon fisheries along the west coast of North America are mixed-stock, recreational systems, in which managers strive to account for interactions between fish, anglers, and management policy while balancing fishery access against conservation of vulnerable stocks. Specific challenges facing fisheries managers include limited control over angling...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

Phylogenetics, Biogeography, Morphological Variation, and Taxonomic Revision of Sandelia capensis (Cuvier 1829) (Anabantiformes: Anabantidae), a Freshwater Fish from the Coastal Streams of the Cape Region, South Africa

Creator:: Bronaugh, Whitcomb Meade
Abstract:: Accumulating human impacts on freshwater ecosystems have created a biodiversity crisis for freshwater fishes while conservation efficacy remains hampered by the Linnaean shortfall, the ignorance of many species that have yet to be discovered and described. The past discovery of most freshwater fish species was simply a matter of collecting...
