Geographic variation in timing of fry emergence and smolt migration of coho salmon (Oncorhynchus kisutch)

Creator:: Spence, Brian C.
Abstract:: The timing of two events in the early life history of coho salmon--emergence from the gravel and entry into the ocean--is presumed to have evolved to ensure maximum survival during these transition periods. Anthropogenic disturbances may disrupt the timing of these events to the detriment of salmon populations. Multivariate analyses...

Geographic variation in genetic and meristic characters of coastal cutthroat trout (Oncorhynchus clarki clarki)

Creator:: Williams, Thomas Herbert
Abstract:: Understanding how populations within a species interact across various geographic and temporal scales is fundamental to developing appropriate conservation strategies. I examined the geographic variation in genetic and meristic characters of coastal cutthroat trout (Oncorhynchus clarki clarki) based on approximately 1,400 fish sampled from 54 populations spanning their distributional range...

Prevalence, geographic distribution, and biology of a dungeness crab, Cancer magister, microsporidian parasite

Creator:: Childers, Richard K.
Abstract:: The microsporidian parasite Nadelspora canceri infects Dungeness crabs, Cancer magister, along the United States Pacific Northwest coast. The prevalence and seasonal variation of N. canceri in Dungeness crabs from Alsea Bay, Oregon, are described based on examination of 2991 crabs collected at monthly intervals from October, 1991 to June, 1993....

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...

Towards an Integrated Decision Tool for Managing Wildlife with Visitor Restrictions in Glacier Bay National Park

Creator:: Whitlock, Steven L.
Abstract:: The National Park Service has a dual mission of providing public access to exceptional natural resources, but in a manner such that these resources are left “unimpaired for the enjoyment of future generations.” Human activities in parks undoubtedly affect wildlife, but the degree to which such activities cause impairment is...

Spatial and Temporal Assessment of Vertically Migrating Myctophids as Biotransporters of Microplastics to Mesopelagic Food Webs

Creator:: Boisen, Olivia C.
Abstract:: It is well documented that microplastics and semi-synthetic particles (<5 mm) pervade the marine environment, with their ingestion by marine fauna eliciting global concern. While fishes exposed to microparticles in a laboratory setting have exhibited both sub-lethal and lethal effects, the diversity in material, morphology, and size of these contaminants...

Development and Evaluation of a Static Land-Based Aquaculture System for Pacific Dulse (Devaleraea mollis): Environmental and Nutrient Requirements

Creator:: Chatfield, Marcus W.
Abstract:: Devaleraea mollis (Pacific Dulse) is becoming a popular food for human consumption. Previously, Pacific Dulse has been used as a nutrient source for cultured abalone species, with some historical food use by indigenous peoples, while the closely related Atlantic dulse (Palmaria palmata) has a long-documented history of use in cuisine...

Population Differentiation in two Northeastern Pacific Marine Species

Creator:: Curran, Lorne Sullivan
Abstract:: Population genetic techniques are now preeminent in differentiating wild populations. Natural resource managers rely on them in their efforts to restore viable populations of fish and wildlife. Overfishing adversely impacted Yelloweye Rockfish (Sebastes ruberrimus) on the U.S. West Coast in the late 20th century. Management actions included shutting down the...

Bacteriophages Significantly Reduce Mortality of Larval Pacific Oysters Crassostrea gigas from Infection by the Pathogenic Bacterium Vibrio coralliilyticus RE98

Creator:: Madison, David B.
Abstract:: Vibrio coralliilyticus (Vcor) is a bacterial pathogen that is well adapted to shellfish hatcheries and is very pathogenic to the larvae of the Pacific oyster Crassostrea gigas. Vcor has been associated with several large scale larval mortality events in the Pacific Northwest that interrupt the supply of seed oysters available...

Diving into Diversity: Fish Populations and Climate Resilience in an Endorheic Basin

Creator:: Dew, Aleah
Abstract:: The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...
