In Southeast Alaska, Eulachon (Thaleichthys pacificus) are a culturally and biologically important anadromous fish. Eulachon populations have significantly declined in the southern part of their range, and in 2010 eulachon in northern California, Oregon, and Washington were listed as a threatened species under the Endangered Species Act. In the same...
Oxidative stress is the major driving force behind the aging process and many age-related diseases. However, direct experimental evidence of whether antioxidants, such as ascorbate (AA) and lipoic acid (LA) can slow the progression of aging process and/or reduce risks of developing degenerative disease is largely absent. This suggests a...
The waterborne, myxozoan parasite Ceratonova shasta is endemic to the Pacific Northwest and can be lethal to its secondary salmonid host, including the culturally, economically, and recreationally important spring Chinook salmon (Oncorhynchus tshawytscha) of the Deschutes River, OR. Previously described genotypes of C. shasta exhibit specificity with their salmonid hosts....
The state of habitats is important for their productivity, including for stocks of commercial fish. Some fishing methods can damage habitat or give bycatch of species. Destructive fishing gear has sometimes been introduced without awareness of the direct negative impacts on habitat, and without realising the possible negative indirect impacts...
Microbial Enhanced Oil Recovery (MEOR) is a process where microorganisms are used for tertiary oil recovery. Numerous mechanisms have been proposed in the literature through which microorganisms facilitate the mobilization of residual oil. Herein, we focus on the MEOR mechanisms of interfacial tension reduction (via biosurfactant) and bioclogging in water-wet...
This paper models and investigates the foreshortening of transferred quota which is applied in the Norwegian fisheries management. This reduction in the transferred quota amount by 20% is then redistributed amongst all vessels in the relevant vessel group. It is shown that fishing units can be expected to be operated...
This paper presents a deterministic bioeconomic model with a marine protected area (MPA) including both fisheries management and tourism development goals. A weighting parameter is added to the model to allow tradeoffs between management preferences regarding the two sectors affected by the MPA. The theoretical model is illustrated with analysis...
The rapid growth of aquaculture affects wild fisheries in several ways. We present a bioeconomic model of the interaction between capture based aquaculture that depending on harvest of wild juvenile organisms with a wild fishery, including an effect of marine reserve implementation. We assume the catch of wild juveniles for...
Pacific lamprey is an important cultural and ecological species to freshwater ecosystems of the Pacific Northwest. Lamprey often rear in low gradient portions of watersheds that have high exposure to climate warming, yet very little is known about their thermal physiology in comparison with other anadromous fishes such as Pacific...
The purpose of this project was to create a code generating software tool, which is one section of the Oregon SpeedCode Universe. The Code Generator automatically generates compilable source code to form working Macintosh applications. This source code provides a prototype for the actual final application. This is done with...
