Lake trout diversity in Great Bear Lake: do deep-water forms exist?
chercheur principal: Muir, Andrew M
Année(s) de permis: 2012 2010
Résumé: 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 ...


Evolution of Arctic Lampreys
chercheur principal: Renaud, Claude B.
Année(s) de permis: 2012
Résumé: The purpose of this study is to know more about the lampreys of NWT. It is part of a larger scale study of lampreys of the genus Lethenteron across the northern hemisphere (Eurasia and North America). In the Northwest Territories (NWT) part of the study our objectives are: 1- To collect a total of about 30 larvae at least 60 mm in total length for each of the two species from localities where a...


Impact of climate change on freshwater fish mercury levels
chercheur principal: Stern, Gary
Année(s) de permis: 2012
Résumé: The objective of this study is to collect fish from lakes and tributary rivers of lakes under fish (mercury) consumption advisories and compare with older data from government if available (DFO, Environment Canada), and to collect and analyse sediment cores from these lakes to see how lake ecosystem changes relate to fish mercury levels. There are two main methods involved in this work. For fis...

Ecological Assessment Field Work for Lue Túé Sulái (the Five Fish Lakes) Candidate Cultural Conservation Area
chercheur principal: Haas, Claudia A
Année(s) de permis: 2012 2011
Résumé: This project is to fill gaps in ecological information on a Candidate Protected Area while it makes its way through the NWT Protected Areas Strategy (PAS) process. This information will be used by the working group to make recommendations on final boundary and management planning for the area. The study will be done at the same time as a study on mercury in fish being conducted by the Dehcho F...


La Martre River Fall Fisheries Program
chercheur principal: Cote, Jason E
Année(s) de permis: 2011
Résumé: Fieldwork is required to determine the potential effects of a ramping event (sudden shutdown of the power generation facility) on fish and fish habitat within the lower reaches of the La Martre River. This information would be added to the overall fish and fish habitat effects assessment and will identify potential mitigation measures, if required. Specific objectives of the field program includ...


Exfiltration Fence Habitat Assessment
chercheur principal: Wilcockson, John B
Année(s) de permis: 2011
Résumé: The objective of this research project is to determine the presence or absence of fish species as part of a habitat assessment of the proposed location for an exfiltration trench (effluent diffuser). Collected fish will be identified, weighted and measured. Electrofishing would be conducted along the banks of a 200m stretch of Prairie Creek, at the Prairie Creek mine site. Electro fishing would...


Dolly Varden Char Assessment in the Peel Plateau

Baseline mercury levels in predatory fish in the Sahtu Settlement Area
chercheur principal: Guthrie, Glen H
Année(s) de permis: 2011 2010
Résumé: 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...
