Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2024 2016 2015 2014 2013
Summary: This licence has been issued for the scientific research application No. 6014. 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 resea...

Summary: This licence has been issued for the scientific research application No.5031. The study is continuing to investigate whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which we have been studying since the early 1990s. The research team plans to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area and also plans ...

Principal Investigator: DELORMIER, Treena
Licensed Year(s): 2011
Summary: The objectives of this research project are: To assess the risk for mercury exposure posed by fish consumption in the community of Tulita in the past summer and current winter seasons; To examine the relationship between the consumption of sweetened beverages (low nutrient market food) and fish consumption; and To explore the social and cultural importance of fish (traditional food) to the Dene...

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...

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...

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...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2005
Summary: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...

Principal Investigator: Fisk, Aaron
Licensed Year(s): 1993
Summary: The researcher plans to take samples of sediments and fish from sites near the three settlements in order to determine the types of contaminants that are present in the environment as well as those that collect or accumulate in the tissues of fish. This study will benefit other studies that have examined contaminants in NWT wildlife as fish are preyed upon by a variety of wildlife species. The r...

Principal Investigator: Lockhart, W.L.
Licensed Year(s): 1993 1992
Summary: As part of this ongoing study, sediment samples will be taken fron the deepest locations of Lac Belot and Colville Lake. These samples will be analyzed for the presence of contaminants and dated. These analyses will allow the researcher to construct histories of the input of contaminants to these lakes. In addition, lake trout, whitefish and burbot will be collected to determine what contaminan...
