Summary: The objective of this study is to collect whitefish and lake trout in the Keith Arm of Great Bear Lake near Deline and analyze tissues for metals and radionuclides. The results of this study will supplement the results of a study conducted in 2009 which reported the concentrations of metals, radionuclides and organo-chlorine pesticides in a small number of trout and herring. Twenty whitefis...

Summary: The objectives of the field program are to quantify egg deposition by depth on available habitat for fourteen known or suspected representative shallow reefs and for ten representative deep water reefs in Nonacho Lake, also to conduct mercury sampling in Lake Trout from this lake. At each of the known or suspected lake trout spawning reefs, a total of 10 numbered egg nets will be buried in cobb...

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...

Summary: The objectives of this study are to collect brain samples from beluga whales harvested in the ISR for contaminant and brain analyses. The researcher will establish whether a link exists between contaminant exposure and brain chemistry. This information is important for understanding whether contaminants are affecting beluga health. Sampling will take place for four to six weeks at Hendrickson...

Summary: The EEM will investigate the cause of differences in fish health that were observed in fish from an area exposed to mine effluent (Jackfish Bay) when compared to fish not exposed to mine effluent (Horseshoe Island Bay). Data will be examined to see what environmental factors are causing the observed effects. Fish Program: A small-bodied fish survey will be conducted within one exposure ar...

Principal Investigator: Katz, Sharon
Licensed Year(s): 2009
Summary: The objectives of this study are: (a) To determine whether brominated flame retardants (BFRs), current use pesticides (CUPs), perfluorinated compounds (PFCs), and mercury bioaccumulate using the vegetation-caribou-wolf food chain and the Bathurst caribou herd as a model; (b) To explore possible sources of lead contamination in the Bathurst herd caribou; (c) To elucidate the pathway of lead uptake ...

Principal Investigator: Sheppard, Steve C
Licensed Year(s): 2008
Summary: This licence is issued for the scientific research application #916. The objective of this research is to measure iodine in the muscles of fish and in their substrate water. The researcher is limited to angling fish for the study within the restrictions of the researcher’s angling licence on Mackay Lake. The researcher will also be completing water samples. They will be limited to no more ...

Principal Investigator: Thompson, Amy L
Licensed Year(s): 2008 2007
Summary: This licence is being issued for the scientific research application # 778. This research will examine the livers of Loche fish in the GSA. This research will be completed through: 1) field collection of loche in each of the GSA communities; 2) biological sampling of loche; 3) analysis of stomach health and aging (using isotopes). More specifically, biological measurements will be taken for ea...

Summary: The objective of this environmental monitoring program is to meet requirements under the Snap Lake Project's Environmental Agreement, Land Use Permit, Water Licence, and Fisheries Authorization, as well as to meet De Beers' corporate commitments to the environment. Information collected during field sampling and observations will build on existing data and will be used towards: 1) contributing to ...

Principal Investigator: Hoyt, Andrea J.
Licensed Year(s): 2006 2005
Summary: In the fall of 2004, the West Side Working Group decided to develop a program to monitor the Big Fish River, involving students from the high school, Hunters and Trappers Committee (HTC) members, and elders. This project will include a week-long field trip each year to the Big Fish River, as well as classroom learning, and reporting back to community members. The project will monitor changes in ...
