Baseline mercury levels in predatory fish in the Sahtu Settlement Area
Principal Investigator: Guthrie, Glen H
Licensed Year(s): 2011 2010
Summary: This study will provide current information about the health of some subsistence predatory fish in ten commonly used lakes by residents of the Sahtu Settlement Area (SSA). This investigation may help to identify alternative sources of fish from lakes not impacted to the degree as seen in Kelly Lake. A future, far more thorough study of mercury abundance and bio-magnification trends may also result...


The Genographic Project: Anthropological Genetic Analyses of Indigenous Human Populations of North America - South Slave and DehCho
Principal Investigator: Schurr, Theodore G
Licensed Year(s): 2011 2010 2009
Summary: In this project, the ancestry and history of the Aboriginal populations of the NWT will be explored through the analysis of genetic diversity in these communities. Through this DNA analysis, the origin and diversity of these aboriginal people will be investigated and their relationship to other aboriginal peoples of Canada and Alaska will be assessed. Overall, this approach will generate new insi...

Bosworth Creek Aquatics and Fisheries Monitoring Program
Principal Investigator: Blaschuk, Katherine
Licensed Year(s): 2011 2010 2009
Summary: WorleyParsons, on behalf of Imperial Oil, began a benthic invertebrate and fisheries assessment program for the portions of Bosworth Creek adjacent to the Imperial Oil operations in Norman Wells, NWT. The objective of the project is to characterize biophysical conditions in Bosworth Creek in the area surrounding the lower Bosworth Creek Bridge; both upstream and downstream from the location of a f...


Fort Good Hope baseline heavy metal accumulation in burbot (loshe) study.
Principal Investigator: Guthrie, Glen H
Licensed Year(s): 2010
Summary: This study will provide baseline data for uranium levels and contribute data to an on-going Department of Fisheries and Oceans (DFO) study that is investigating mercury levels in Fort Good Hope burbot (Loshe). Thirty fish representing three size/age classes will be collected by the Fort Good Hope (FGH) Renewable Resources Council (RRC). The samples will be sent to reputable laboratories that sp...


The Continuation of a Community-led Fish Monitoring Study in Déline, NT
Principal Investigator: Macdonald, Colin R
Licensed Year(s): 2012 2010 2009
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...


7 Mine Site Project
Principal Investigator: Widmeyer, Joline
Licensed Year(s): 2010
Summary: The objective of this study is to identify what fish species are in Ruth Lake and Bullmoose Lake and to conduct tissue sampling which will assist in determining if the fish in these lakes are bioaccumulating heavy metals. Fish will be sampled using techniques such as minnow trapping, seining, gill netting, angling and possibly boat electrofishing. Nets and minnow traps may be left at the sam...


Nonacho Lake Trout Study Program
Principal Investigator: Cote, Jason E
Licensed Year(s): 2010
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...


Enhanced Investigations of the Factors affecting Long-term Contaminant Trends in Predatory Fish in Great Slave Lake, Northwest Territories
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2010 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...
