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; …

Interactions between Lake Trout and Bull Trout in the Priest Lake system, Idaho
… directional movements, and distributions of Bull Trout and Lake Trout between Priest Lake and Upper Priest Lake, Idaho, were studied from May 2015 to April 2017. Lake Trout (n=220) and Bull Trout (n=40) movements were monitored using Lotek JSATS transmitters and hydrophones both passively, using …

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 …

TROPHIC ECOLOGY OF JUVENILE LEAN AND SISCOWET LAKE TROUT (SALVELINUS NAMAYCHUSH) FROM U.S. WATERS OF LAKE SUPERIOR
… isotopic niches of juvenile Lean and Siscowet Lake Trout ecotypes across six ecoregions of Lake Superior. Spatially, Lean and Siscowet were observed in overlapping depth distributions. Leans were most abundant in shallow waters (60m). The greatest levels of cohabitation were observed in waters …

The Effect of Highly Unsaturated Fatty Acids (HUFA) on Lake Trout (Salve linus namaycush) Alevins Using Artemia nauplii Enriched with Commercial Emulsions and Dry Diets
… survival, growth, and fatty acid profiles in lake trout (Salvelinus narnaycush) alevins, two 8-week feeding experiments were performed. Diets used in the Artemia Experiment included: diet 1, non-enriched Artemia; diet 2,SELCO-enriched Artemia; diet 3, Super SELCO-enriched Artemia; and diet 4, …

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 …

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 …

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 …

Comparison of polychlorinated biphenyl profiles in rat, fish and human tissues; the effects of consuming Great Lakes fish
… after the consumption of contaminated Great Lakes fish. Fish from Lake Superior (LS), Lake Michigan (LM), and Lake Huron (LH) were examined for either total PCB or specific congener concentrations. Total PCBs were highest in carp, lake trout and siscowet lake trout compared to walleye, …

Causes and Consequences of a Collapsing Food Web in Lake huron
Lake Huron has undergone significant declines in abundance at multiple trophic levels. These declines are demonstrated to be the result of a decrease in the overall primary production, from an estimate of 100 g C m -2 yr-1 in the 1970s. to 32 g C m-2 yr -1 in this study. It is hypothesized that …

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 …
