Summary: This licence has been issued for the scientific research application No. 6000. The study is continuing to investigate whether contaminant (mercury, other metals, persistent organic contaminants) levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the team have been studying since the early 1990s. The plan is to arrange collections of lake trout from t...

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 ...

Summary: This licence has been issued for the scientific research application No.4844. 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...

Summary: It is the objective of this project to collect information on the walleye population from the Horn River which can be used for managing the fishery and possibly changing the regulations. In order to reach this objective the following goals have been set out: 1. to collect population structure and spawning information by setting gill nets of varying mesh size and biologically sampling a portion of...

Summary: The objectives of this project are to: 1) continue to investigate trends in mercury, metals and persistent organic contaminants (POCs) in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in Great Slave Lake in 2017 to further extend the long-term (1993-2015: POCs, 1993-2016 mercury a...

Summary: The primary objective of this project is to enhance Providence Creek to increase arctic grayling (Thymallus arcticus) spawning habitat. This will be done by removing beaver dams which have been shown to decrease usable spawning habitat, and to create new spawning habitat with gravel and boulders. Another objective of the project is to monitor the arctic grayling population to determine if the ...

Summary: The objectives of this project are: 1) to determine through which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes; 2) to train community monitors to collect fish and other samples according to Environment Canada and Department of Fisheries and Oceans protocol; 3) to involve local school children in the studies by ...

Summary: The objectives of this research project are to: 1) determine why fish mercury levels vary among lakes in the Dehcho region; 2) identify best predictors of fish mercury levels; and, 3) determine which fish have the lowest levels of mercury and highest levels of micro-nutrients and fatty acids. The methods for this project include two parts, first is the collection of food web data from each lake...

Summary: The overall objective of this research is to promote country foods in the Dehcho Region in a way that balances contaminant risks and nutrient benefits in order to maximize nutrient status while minimizing mercury exposure. The research team will work towards this objective through the implementation of pilot research that will: 1) develop a locally-relevant dietary survey, 2) evaluate the dietary ...
