Nonacho Lake Trout Study Program
Principal Investigator: Cote, Jason E
Licenced Year(s): 2010
Summary: The objectives of the field program are to quantify egg deposition by depth on available habitat for fourteen known or suspected representative shallow reefs and for ten representative deep water reefs in Nonacho Lake, also to conduct mercury sampling in Lake Trout from this lake. At each of the known or suspected lake trout spawning reefs, a total of 10 numbered egg nets will be buried in cobb...


Enhanced Investigations of the Factors affecting Long-term Contaminant Trends in Predatory Fish in Great Slave Lake, Northwest Territories
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2010 2009
Summary: For several years, studies have been conducted to find out if contaminant levels are changing in lake trout and burbot in Great Slave Lake. The researchers have been seeing some changes with mercury levels increasing and HCH levels declining in these fish. However, there have been other changes in the fish, especially lake trout which appear to contain less fat and to be feeding closer to shore th...


Giant Mine Phase 3 EEM
Principal Investigator: Machtans, Hilary
Licenced Year(s): 2012 2010
Summary: The objective of the study is to examine fish health of two small-bodied species in the exposure and reference areas – likely slimy sculpin and ninespine stickleback. A small-bodied fish survey will occur within the exposure area (mouth of Baker Creek) and a reference area (Yellowknife River/Yellowknife Bay). Small-bodied fish will be captured and measured for weight and fork length, using bea...


Collecting of Parasitic wasps (Hymenoptera: Braconidae: Microgastrinae)
Principal Investigator: Goulet, Henri
Licenced Year(s): 2010
Summary: The research plan is to collect specimens of as many species (named or not) of the wasp subfamily Microgastrinae (Hymenoptera: Braconidae) to get recent and properly preserved specimens for DNA barcoding and taxonomic resolution. The goal is to know more about the diversity of these wasps and to be able to compare the recently wasp fauna with re-identified specimens sampled in the 1950’s. To achi...


Inuvik to Tuktoyaktuk Highway Project
Principal Investigator: Moore, Steve M
Licenced Year(s): 2010
Summary: The objectives of this study are to determine the presence of fish and the quality of fish habitat at stream crossings along the proposed road alignment. They will be achieved through observations, measurements, and surveys carried out during freshet. These observations will provide an indication of seasonal habitat use at high water, when connectivity to upstream habitats may exist. Similarly, ...


Flora of the Canadian Arctic - diversity and change
Principal Investigator: Gillespie, Lynn J.
Licenced Year(s): 2010 2009
Summary: The Research long term goals are to: 1) produce the first “Flora of the Canadian Arctic”, a field guide to all plant species of the Canadian arctic; 2) implement an Arctic Plant website to provide easy access to information; 3) undertake studies on diversity and distribution of arctic plants and mosses; and 4) obtain DNA barcodes for all Canadian Arctic plants. The objectives on Victoria Island in...


Molecular analysis of evolutionary change in stickleback populations
Principal Investigator: Shapiro, Michael D.
Licenced Year(s): 2010 2008 2007 2005 2004 2002 2001 2000
Summary: The researcher plans to collect stickleback fish from Fox Holes Lakes. These fish will be used for laboratory experiments to determine the genes that control the number, shapes, and sizes of bones in the skeleton. Two members of the research team will travel to Ft. Smith for approximately 5 days during the broader time interval listed (May 1 - June 30 of each year). The most likely time for our...


Linking Neurochemistry to Contaminant Exposure in Belugas of the Mackenzie Delta
Principal Investigator: Ostertag, Sonja K
Licenced Year(s): 2010 2008 2006
Summary: The objectives of this study are to collect brain samples from beluga whales harvested in the ISR for contaminant and brain analyses. The researcher will establish whether a link exists between contaminant exposure and brain chemistry. This information is important for understanding whether contaminants are affecting beluga health. Sampling will take place for four to six weeks at Hendrickson...


2008-2010 Baseline Studies for Avalon Ventures Ltd. Proposed Thor Lake Rare Earth Metals Project-Fisheries Component
Principal Investigator: Lawson, Nick
Licenced Year(s): 2010 2009 2008
Summary: The fisheries portion of this baseline program has three primary objectives: to identify the fish species composition in a subset of the lakes and streams near the Thor Lake project area, to identify existing fish habitat in those lakes and streams, and to measure the current levels of mercury, rare earth elements and other trace elements in fish tissues. A secondary objective of the program is to...


Lutsel K'e Hydro Power Project - 2010 Winter Monitoring Program
Principal Investigator: Cote, Jason E
Licenced Year(s): 2010 2009
Summary: To determine the effects of low-flow conditions on overwintering fish habitats in target area. This will include water depth and velocity transects, fish sampling and dissolved oxygen level measurements. Sampling efforts will be focused on the habitats associated with the diversion reach of the Project and will also include habitats immediately upstream and downstream. At select locations, ic...
