Description du projet: This project will examine the adaptation of freshwater fish to low temperatures. The data to be collected includes blood and tissue samples from fish. These samples will be analyzed for enzymes, fats and proteins. These results will be compared to samples taken from other locations (e.g. Nunavut, southern waters). This work will provide important information relating the sensitivity of Arctic animals to temperature change and ultraviolet damage. The researchers will be based in Yellowknife and use charter flights to access lakes close to Yellowknife. The species sampled will include: grayling, Arctic char, pike, lake whitefish, lake trout, perch and walleye. At each site 10 fish from each species will be caught by angling.
