Analyzing the diet composition of Lake Trout (Salvelinus namaycush) in Upper Priest Lake
<p>Lake Trout (Salvelinus namaycush) were intentionally introduced to the Priest Lake system in 1925 with the intentions of creating a recreational fishery. As the Lake Trout population increased within this system, the native Bull Trout (Salvelinus confluentus) population began to decline. …

An investigation of the factors affecting mercury accumulation in lake trout, Salvelinus namaycush, in northern Canada
… explain the elevated mercury concentrations in lake trout (Salvelinus namaycush), a predatory aquatic fish species in some lakes in northwestern Canada. High mercury concentrations in lake trout in other regions have been associated with the biological features of the fish and various chemical …

Population structure of lake trout (Salvelinus namaycush) In Atlin Lake, British Columbia and contributions to local fisheries: a microsatellite DNA-based assessment
… management programs to be developed. Atlin Lake is a large lake in northern British Columbia and is one of the largest lakes that contain relatively unperturbed populations of lake trout (Salvelinus namaycush). As the top aquatic predator, lake trout in Atlin Lake are a key component of the …

Evaluating the effects of rainbow smelt on native piscivores in freshwater systems with a special focus on walleye recruitment and larval bioenergetics
… species, Atlantic salmon (Salmo salar), lake trout (salvelinus namaycush) and walleye (Sander vitreus). Differences in larval rearing strategies were indentified as the most important factor in determining the nature of effects of rainbow smelt.In particular, larval walleye experience …

Interpreting Predator – Prey Interactions in Cayuga Lake Fishes Using Fatty Acid Signature Analysis
… webs. Therefore, to better understand Cayuga Lake food web dynamics, fatty acid signatures (FAS) of lake trout (Salvelinus namaycush) were compared to two major prey species in the lake; alewife (Alosa pseudoharengus) and round goby (Neogobius melanostomus). The main objectives of the study …

Factors Influencing the Distribution of Bull Trout and Westslope Cutthroat Trout West of the Continental Divide in Glacier National Park
The reported decline of native bull trout Salvelinus confluentus and westslope cutthroat trout Oncorhynchus clarkii lewisi populations west of the Continental Divide in Glacier National Park (GNP) prompted research to identify critical habitats and investigate factors influencing their distribution …

Factors Influencing the Distribution of Bull Trout and Westslope Cutthroat Trout West of the Continental Divide in Glacier National Park
The reported decline of native bull trout Salvelinus confluentus and westslope cutthroat trout Oncorhynchus clarkii lewisi populations west of the Continental Divide in Glacier National Park (GNP) prompted research to identify critical habitats and investigate factors influencing their distribution …

Behavioural Ecology of Lake Trout: From Movement Ecology to Bioenergetics
… investigates the behavioural movements of Lake Trout (Salvelinus namaycush), a top predator fish, in four lakes that differ in the prey community that support them. The study was completed using a relatively new telemetry-transmitter that measures acceleration on two axes of the fish body; …

Consequences of Spatial Exploitation in Complex Adaptive Social-Ecological Systems: Managing for Sustainable Freshwater Fisheries
… models and empirical case studies on the rainbow trout Oncorhynchus mykiss and lake trout Salvelinus namaycush fisheries of British Columbia and Yukon to find the landscape, social, and ecological consequences of spatial exploitation on these complex systems. In general, I found that system …

EFFECTS OF ANTIMICROBIAL COMPOUNDS ON EARLY LIFE STAGES OF CANADIAN FISH SPECIES
… (ELS) of three freshwater fish species: rainbow trout (Oncorhynchus mykiss), lake trout (Salvelinus namaycush), and white sucker (Catostomus commersonii). The overarching goal was to characterize species-specific responses to these contaminants and to identify molecular and apical endpoints that …

Tracing the effects of diets in freshwater fish using fatty acid profiles
… how fatty acid profiles of prey are reflected in lake trout (Salvelinus namaycush) after 14 weeks of feeding. Juvenile lake trout were fed one of three prey species and individuals were sampled at 4, 8 and 14 weeks. Through comparison of consumer fatty acid proportions to those of their diet, it …

Lake Food Web Responses Across Environmental Gradients
… new dataset that I have assembled from Canadian lakes to show that trophic pathways can vary in predictable ways across environmental gradients. These findings provide new insight into an emerging research area that asks how the environment determines the macroscopic properties of food webs. …
