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...

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...

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...

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...

Summary: The first objective is to collect, analyze and report the findings from station-based and continuous plankton sampling and data on depth, temperature and salinity in the upper water column throughout Canada’s Northwest Passage. As a contribution to marine climate change research, this program will provide northern communities with the first regional-scale view of marine productivity—thereby provid...

Principal Investigator: Carson, Richard J
Licensed Year(s): 2017 2015
Summary: The objectives are to evaluate if there are differences in biological parameters among study sites and between years at the Tungsten Mine site; as well as to determine whether observed differences from the most recent (2015) Environmental Effects Monitoring study are still present and whether any differences are the result of mining practices. The study objectives are to evaluate fish health, ...

Licensed 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 2017 and an additional 60 samples at the Hornaday River in August 2017, collecting data on: species, location, date/time, catch effort/gear type, length, weight, sex, maturity, otolith, stomach content (frozen)...

Summary: The objectives of this project are to: 1) continue to investigate trends in mercury, metals and persistent organic contaminants (POCs) in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in Great Slave Lake in 2017 to further extend the long-term (1993-2015: POCs, 1993-2016 mercury a...

Licensed Year(s): 2017
Summary: The purpose of this project is to remove the majority of fish from within the A21 dike and transfer into Lac de Gras to allow for dewatering and construction to occur. The General Fish-out Protocol separates fishing effort into two phases. The Phase 1 fishing effort will begin with short duration gill nets and trap nets to target live release of fish into Lac de Gras. Fish captured will be tran...

Licensed Year(s): 2016
Summary: The objectives of this project are to apply short term sublethal exposures to contaminants of concern with locally collected small bodied fish to establish measures of the relative bioavailability and effect in the Slave River. This information will then be applied to the Community Based Monitoring (CBM) program data to assess exceedances in a more comprehensive manner. Small fish (for exampl...
