Summary: The goal of this project is to determine the levels of potential chemicals of concern in three major fish species through the analysis of muscle and liver samples for mercury, radionuclides and a number of elements. Fish of three species (lake trout, lake whitefish and lake herring) will be collected in the Keith Arm of Great Bear Lake near the community of Deline. Approximately 15 trout and 10...

Summary: The Objectives of this research project are to: 1.) gather information in 2012 on the small-bodied and Young of Year fish in Bluefish Lake that may be available for monitoring as well as determine the most suitable methods and locations for their capture in order to finalize the proposed mercury study design, and 2.) complete monitoring between 2013 and 2015 as described in the finalized mercury ...

Principal Investigator: Muir, Andrew M
Licensed Year(s): 2012 2010
Summary: The objective of this project is to sample known and newly discovered deepwater (>50 m) habitats southwest of the Narakay Islands and within the McTavish Arm to determine if a deepwater humper or siscowet lake trout form occurs. Data on the occurrence and characteristics of deepwater lake trout forms from Great Bear Lake will fill in gaps in this North American lake trout dataset. Currently it is ...

Principal Investigator: Reed, Shawna
Licensed Year(s): 1994
Summary: In this study fish presence/absence and/or densities will be obtained by electrofishing representative habitat and the setting of baited minnow traps. When these two methods are not practical gill nets, trap nets, and/or beach seines will be employed. Each fish caught will be identified, measured, sexed and condition will be noted. Ten specimens of each species from each site (up to 10) will be...

Principal Investigator: Schwalme, Karl
Licensed Year(s): 1988
Summary: Karl Schwalme wants to know how and why the fat content of pike changes during the year. He will collect about 30-50 great northern pike from each lake by using a 2 1/2 inch gill net which will only be set during the day. He will then take the fish back to the Inuvik Research Centre to determine their fat content. Since some of the fats help to prevent heart disease in people, the annual change ...
