Further Examination of the Bio- Magnification of Mercury within Fish Species and watersheds of the Deh Cho and Their Varying Levels Among Lakes
Principal Investigator: Low, Mike
Licensed Year(s): 2024 2023 2021 2019
Summary: This licence has been issued for the scientific research application No.5348. The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients; and, 4) to collect data on parameters that ...


Impact of climate change on freshwater fish mercury levels
Principal Investigator: Stern, Gary
Licensed Year(s): 2012
Summary: The objective of this study is to collect fish from lakes and tributary rivers of lakes under fish (mercury) consumption advisories and compare with older data from government if available (DFO, Environment Canada), and to collect and analyse sediment cores from these lakes to see how lake ecosystem changes relate to fish mercury levels. There are two main methods involved in this work. For fis...
