Spatial and long-term trends in persistent organic contaminants and metals in lake trout and burbot from Great Slave Lake
Principal Investigator: Evans, Marlene S.
Licenced Year(s): 2018 2016
Summary: This study is continuing to investigate whether contaminant levels are changing in fish in Great Slave Lake which the team have been studying since the early 1990s. The research team will collect lake trout from the Hay River and Lutsel K’e areas. The team will also plan to collect burbot from the Lutsel K’e and Fort Resolution areas of Great Slave Lake, and northern pike from the Fort Resolution ...


Con Mine Phase 6 EEM - Periodic Monitoring
Principal Investigator: Irving, Elaine
Licenced Year(s): 2018 2015 2012 2009 2007
Summary: The objective of the study is to carry out the third year of periodic monitoring of fish and benthos at the determined study locations; Jackfish Bay (exposure area), Horseshoe Island Bay (reference area for fish survey) and Kam Bay (reference area for the benthos survey), to determine if treated Con Mine effluent is affecting fish and fish habitat. The study has been designed to replicate the stud...


Horn River Creel Survey and Stock Study
Principal Investigator: Low, George
Licenced Year(s): 2018 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...


Sanguez Lake Fish Down Study
Principal Investigator: Low, George
Licenced Year(s): 2018 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...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs), including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT
Principal Investigator: Stern, Gary
Licenced Year(s): 2018
Summary: The short-term goals are to determine if 2018 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); and 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association (Carrie et al. 2010); as well as...


Metals levels in large bodied fishes near impacted lakes near Yellowknife, NWT
Principal Investigator: Somers, Gila L
Licenced Year(s): 2018 2017 2016
Summary: The objectives of this project are to collect fish tissue samples from species of subsistence importance to: 1) establish a long-term community monitoring program for contaminants in fish; and, 2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Yellowknife region. The data acquired will be added to existing and concurrently co...


How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
Principal Investigator: Gray, Derek K
Licenced Year(s): 2018 2017
Summary: Purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and mediu...


De Beers Canada Snap Lake Mine Environmental Monitoring
Principal Investigator: Hood, Alexandra E
Licenced Year(s): 2018 2017 2016 2015 2014 2012 2011 2010 2009 2008 2007 2006 2005 2004 2002 2001 2000 1999
Summary: This research is intended to meet regulatory requirements from the Snap Lake Environmental Assessment and under the mine's Water License, Land Use permit and Environmental Agreement. The objectives of this research project are to obtain and determine annual variability of the relative abundance, distribution, group composition and behaviour of caribou; the relative activity of grizzly bears; t...


Further Examination of the Bio- Magnification of Mercury within Fish Species of the Deh Cho and their Varying Levels among Lakes
Principal Investigator: Swanson, Heidi
Licenced Year(s): 2018 2017 2016 2016 2015 2014 2013
Summary: The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; and, 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients. The methods for this project include field sampling, laboratory analysis, and data analysis and reporting. The resea...


Ekati Engineering and Environmental Monitoring Programs
Principal Investigator: Pacholski, Laura J
Licenced Year(s): 2018 2017 2016 2015 2014 2013
Summary: The main objectives of the field work for 2018 will be to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment and air quality, and to provide baseline data for areas where mine development may occur in the future. In winter, water samples will be collected under ice using a 2.5L Niskin (a cylindrical PVC water sampler). During the week of spring fresh...
