Assessment of the hatchery kokanee (Oncorhynchus nerka) release program in Lake Roosevelt 2009 -- 2012
<p>This study determined which kokanee stock performed best in Lake Roosevelt, WA: Lake Whatcom, Meadow Creek, or F1 mixed stock. The F1 mixed stock was created by collecting eggs from Lake Whatcom, Meadow Creek and non-marked kokanee that returned to Hawk Creek and raising them to the residualized …

Drivers and Fitness Consequences of Dispersal and Structure in Wild Sockeye Salmon Populations (Oncorhynchus nerka)
… stream-spawning populations of Sockeye salmon (Oncorhynchus nerka): A and C Creeks on the Wood River System, Bristol Bay, AK was studied over two complete generations of returning adults. First, a panel of 172 SNP loci was developed (genotyping-in-thousands by sequencing; Chapter One) and used …

Impacts of Spawning Sockeye Salmon (ONCORHYNCHUS NERKA) on Benthic Macroinvertebrate Production in the White River, WA
<p>This research was conducted to determine the effects of salmon mediated marine-derived nutrient subsidies on benthic macroinvertebrate production. The Cascade Columbia Fisheries Enhancement Group (CCFEG) is evaluating whether stream nutrient enhancement might benefit struggling salmon …

Early Life History and Stock Discrimination of Kokanee Salmon (Oncorhynchus nerka) in an Alpine Lake Environment
… important population of kokanee salmon (<em>Oncorhynchus nerka</em>) residing in Keechelus Lake and its tributary Gold Creek in the central Cascades of Washington State. This population of kokanee salmon is a vital food base for a population of ESA-listed resident bull trout. However, little …

Sedimentary legacy of sockeye salmon (Oncorhynchus nerka) and climate change in an ultra-oligotrophic, glacially-turbid British Columbia nursery lake
Anadromous Pacific salmon (Oncorhynchus spp.) populations are strongly regulated by climatic regimes and human activities across numerous spatial and temporal scales. The carcasses of adults returning to spawn provide important marine derived nutrients (MDN) to freshwater and terrestrial ecosystems …

The role of fish physiology, behaviour, and water discharge on the attraction and passage of adult sockeye salmon (Oncorhynchus nerka) at the Seton River dam fishway, British Columbia
… and passage for the Gates Creek sockeye salmon (Oncorhynchus nerka, Walbaum) stock at the Seton River dam in British Columbia. The first part of this thesis examined the effect of changes in water discharge from the dam on the relationship between the physiological condition of sockeye and their …

Bayesian statistics for fishery stock assessment and management
… Real data refer to Skeena river salmon (Oncorhynchus nerka), Orange Roughy (Hoplostethus atlanticus) and Pacific cod (Gadus macrocephalus). The results show that the technique successfully approximates posterior distributions in higher dimensions even if such distributions are multimodal. …

Determinants for the Timing of Escapement From the Sockeye Salmon Fishery of the Copper River, Alaska: A Simulation Model
… population of Copper River sockeye salmon (<em>Oncorhynchus nerka</em>) was reconstructed in the reference frame of the commercial harvest area from catch and escapement data.</p> <p>The catchability coefficients (q), derived from the reconstructed populations were found to vary within season …

The Gut Microbiome and its Relationship to Migratory Behaviour and Fate in Wild Fishes
… sucker (Catostomus commersonii), sockeye salmon (Oncorhynchus nerka), and brown trout (Salmo trutta). Further, I highlighted the importance of transitioning to non-lethal sampling methods when studying wild fish microbiomes, especially in relation to studying behaviours. Gut microbial analysis …

Food–web implications of reintroducing anadromous salmonids in reservoirs on the North Fork Lewis River, Washington
… River in Washington State. Spring Chinook Salmon Oncorhynchus tshawytscha and Coho Salmon O. kisutch have been observed rearing in several lakes and reservoirs elsewhere, raising the question of the potential for reservoir habitat to contribute to smolt production in the Lewis River. To determine …
