Temporal trend studies of trace metals and halogenated organic contaminants (HOCs) including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT (2024-2025)
Principal Investigator: Stern, Gary
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5906. Short-term goals are to determine if burbot contaminant concentrations: • Are above or below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish). Annual data will be provided to NWT Health and Social Services for evaluation; • Are associated with dietary indicators, i.e. stable isotope ratio data (15N, 1...

Temporal trend studies of trace metals and halogenated organic contaminants (HOCs), including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT.
Principal Investigator: Stern, Gary
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.4755. The short-term goals are to determine if 2021 and 2022 burbot contaminant concentrations: a) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish). The research team will provide annual data to NWT Heath and Social Services for evaluation; b) are associated with dietary indicators, i.e. stable is...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs), including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT.
Principal Investigator: Stern, Gary
Licensed Year(s): 2019
Summary: The short-term goals are to determine if 2019 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association; and, 3) as well as to look for link...

Principal Investigator: Stern, Gary
Licensed Year(s): 2018
Summary: The short-term goals are to determine if 2018 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); and 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association (Carrie et al. 2010); as well as...


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...
