Principal Investigator: Low, Mike
Licensed Year(s): 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 ...

Monitoring of mercury, flame retardants and other chemicals in lake trout and cisco from Great Bear Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4675. This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. Of particular interest is mercury.

Sanguez Lake Fish Down Study
Principal Investigator: Low, George
Licensed Year(s): 2021 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.4573. The objectives of this study are to: 1) establish a population estimate of walleye in Sanguez Lake; 2) establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3) reduce the n...

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: Somers, Gila L
Licensed Year(s): 2018 2017 2016
Summary: The objectives of this project are to collect fish tissue samples from species of subsistence importance to: 1) establish a long-term community monitoring program for contaminants in fish; and, 2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Yellowknife region. The data acquired will be added to existing and concurrently co...
