Mercury concentrations and biological information on the Husky Lakes, Northwest Territories

We are using a mixed methods approach and drawing upon both Traditionnal Knowledge (TK) and science to study the limnology (water) and ecology (food web) of this lake and its watershed. Our study aimed to investigate the interactions of water column, food webs and Hg transfer in four freshwater systems in the Inuvialuit Settlement Region. We investigate how those characteristics affect Hg transfer in Husky Lakes, Big, Yaya Lake and Noell Lake (we utilized several other lakes for comparison or additional data). All lakes are frequented by the Inuvialuit communities Inuvik and Tuktoyaktuk for subsistence fishing and the sampling locations and target species were determine by local people during TK interviews. We have and will analyze contaminants in water, sediments and the food web to help explain contaminant concentrations in fishes utilized by local fishermen (e.g., Lake Trout and Lake Whitefish). A majority of Lake Trout samples used in this study were donated to the scientists by local fishermen. Sampling includes tissues from harvested fishes, newly collected non-target fishes, and food web compartments (periphyton, zooplankton, and benthos). Biological parameters of fishes (age, length, weight, diet) are recorded and invertebrates separated by species.
