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. It complements ongoing fish population studies being conducted by the Department of Fisheries and Oceans on Great Bear Lake and contributes to Deline's resear...

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...

2013 Summary:
This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake.
The research team require fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from Great Bear Lake. The fish will be frozen immediately after capture and shipped to Environment Canada-Saskatoon. The fish will then ...

2009 Summary:
For several years, studies have been conducted to find out if contaminant levels are changing in lake trout and burbot in Great Slave Lake. The researchers have been seeing some changes with mercury levels increasing and HCH levels declining in these fish. However, there have been other changes in the fish, especially lake trout which appear to contain less fat and to be feeding closer to shore th...
