Factors affecting the timing and success of sockeye salmon spawning migrations
… timing, I physiologically biopsied over 1000 sockeye salmon and monitored their subsequent behaviour with acoustic and radio telemetry as they migrated from the Pacific Ocean toward and into the Fraser River, and then onward to distant spawning areas. Links between physiology, behaviour, and …

Drivers and Fitness Consequences of Dispersal and Structure in Wild Sockeye Salmon Populations (Oncorhynchus nerka)
The life histories of migratory species such as salmonids, sea turtles, and birds often involve return migrations between feeding and natal habitats. These natal homing behaviors are known to produce structured metapopulations, where geographic and demographic barriers result in non-random mating …

Assessing the limiting factors for re-introduction of sockeye salmon to the Coquitlam Water Supply Area
Prior to the construction of the dams, migrating salmonid species accessed the upper reaches of the Capilano, Seymour, and Coquitlam watersheds as an integral part of their natural lifecycle. There are multiple initiatives being undertaken by BC Hydro and the stakeholders to re-introduce sockeye …

Impacts of Spawning Sockeye Salmon (ONCORHYNCHUS NERKA) on Benthic Macroinvertebrate Production in the White River, WA
… 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 populations in the …

THE LIFE HISTORY AND ECOLOGY OF RIVERINE SOCKEYE SALMON (ONCORHYNCHUS NERKA) IN A LARGE FLOODPLAIN RIVER
The productivity and life history diversity of salmonids is linked to the complexity of habitat in large floodplain rivers. Dynamic floodplain processes are driven by flow, sediment transport, cut and fill alluviation, woody plant succession, and ecosystem engineers, notably beavers, that create …

Determinants for the Timing of Escapement From the Sockeye Salmon Fishery of the Copper River, Alaska: A Simulation Model
… timing of catch and escapement in a terminal salmon fishery is presented. A method was developed to estimate average seasonal migration rates of salmon through a harvest area from catch and escapement data. The time series for the total population of Copper River sockeye salmon …

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
… attraction 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 …

The making of an American ichthyological empire: how the structure of perpetual exploitation of Bristol Bay salmon developed in southwest Alaska, 1883-1970s
… studies the historical development of salmon fisheries in Bristol Bay off southwest Alaska from the pre-contact era to the 1970s. More specifically, it examines how Anglo- Americans constructed and maintained vibrant salmon fisheries in Bristol Bay during the period. This project …

The Gut Microbiome and its Relationship to Migratory Behaviour and Fate in Wild Fishes
… white 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 …

Cultural Politics and Mining Development in Alaska's Bristol Bay Fishery
… world’s largest remaining commercial harvest of sockeye salmon (Oncorhyncus nerka). In the previous decade, the transnational mining industry has intensified its efforts to develop open-pit mining operations near the headwaters of the region’s Kvichak and Nushagak river drainages. In light of …

Resource Debate in Southwest Alaska: The Bristol Bay Fishery and the Pebble Mine
… Bay, in Southwest Alaska, is the largest sockeye salmon fishery in the world. After an almost total collapse of salmon numbers in the mid 1970’s, the salmon have returned and average in the tens of millions every year. The salmon play a vital economic, cultural, and subsistence role in the …
