Genetic assessment of Inconnu (Stenodus leucichthys) in Great Slave Lake, Northwest Territories
Principal Investigator: Tallman, Ross F
Licenced Year(s): 2017
Summary: The objective is to use Inconnu genetic samples to differentiate the inconnu populations residing in Great Slave Lake. If inconnu are philopatric (return to their natal spawning grounds) than each river should consist of a genetically distinct population. Methods include using gill nets to capture between 30 to 50 Inconnu per location (along Buffalo River, Buffalo Lake and Taltson River). Nets...


Sanguez Lake Fish Down Study
Principal Investigator: Low, George
Licenced Year(s): 2017
Summary: Objectives of this research are to: 1) establish a population estimate of walleye in Sanguez Lake; 2) establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3)reduce the number of walleye and pike adults such that predation on walleye recruits decreases....


Horn River Creel Survey and Stock Study
Principal Investigator: Low, George
Licenced Year(s): 2017
Summary: It is the objective of this project to collect information on the walleye population from the Horn River which can be used for managing the fishery and possibly changing the regulations. In order to reach this objective the following goals have been set out: 1. to collect population structure and spawning information by setting gill nets of varying mesh size and biologically sampling a portion of...


NTPC Bluefish Hydro Repairs
Principal Investigator: Panayi, Damian
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010
Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...


Paulatuk Whitefish Assessment
Principal Investigator: Ruben, Diane
Licenced Year(s): 2017 2016
Summary: The objectives of the research are to conduct an assessment of whitefish diet and contaminants. Two technicians will collect approximately 60 samples over 7 days at Billy’s Creek in July 2016 and an additional 60 samples at the Hornaday River in August and October 2016. Data will be collected on: species, location, date/time, catch-effort/gear type, length, weight, sex, maturity, otolith, stom...


Enhancement and monitoring of arctic grayling spawning habitat at Providence Creek, NWT
Principal Investigator: Low, George
Licenced Year(s): 2016 2015 2014
Summary: The primary objective of this project is to enhance Providence Creek to increase arctic grayling (Thymallus arcticus) spawning habitat. This will be done by removing beaver dams which have been shown to decrease usable spawning habitat, and to create new spawning habitat with gravel and boulders. Another objective of the project is to monitor the arctic grayling population to determine if the ...


EL462 & EL463 2013-2014 Biolophysical Baseline Study
Principal Investigator: Hansen, Ken
Licenced Year(s): 2013
Summary: The objective of the project is to identify the fish species present, and to gather population data on surveyed species, in waterbodies in the area of Husky’s proposed exploration activity. Four streams and four to seven small lakes are proposed to be assessed. The Cumulative Impact Monitoring Program recommended selecting 2-4 streams appropriate for collection of baseline information that can...


Bluefish Lake Mercury Monitoring
Principal Investigator: Dewar, David J
Licenced Year(s): 2012
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 ...


Aquatic Environmental Effects Monitoring - Flat River at Cantung Mine
Principal Investigator: Hoos, Rick
Licenced Year(s): 2012 2009 2002
Summary: The objectives of this research are: (1) to determine length, weight, and general condition of 100 fish and tissue analysis of not more than 10 fish (Slimy Sculpin- Cottus cognatus) per site at five site locations in the Flat River: two locations upstream of the CanTung mine site, one adjacent to the mine site and at two locations downstream of the mine site; and, (2) to determine sediment and w...


Lake trout diversity in Great Bear Lake: do deep-water forms exist?
Principal Investigator: Muir, Andrew M
Licenced 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 ...
