Exfiltration Fence Habitat Assessment
Principal Investigator: Wilcockson, John B
Licenced Year(s): 2011
Summary: 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
Principal Investigator: Maier, Kris
Licenced Year(s): 2011
Summary: The objectives of this research project are: 1) to re-assess the anadromous component of the known Vittrekwa River Dolly Varden char population; 2) to investigate & assess other potential suitable Dolly Varden habitat; and 3) to confirm the presence of Dolly Varden char in the Stony Creek watershed. For the Vittrekwa River the research team plans to construct a fixed weir which will trap se...

Traditional and market food: focus on fish consumption in Tulita, NWT
Principal Investigator: DELORMIER, Treena
Licenced Year(s): 2011
Summary: The objectives of this research project are: To assess the risk for mercury exposure posed by fish consumption in the community of Tulita in the past summer and current winter seasons; To examine the relationship between the consumption of sweetened beverages (low nutrient market food) and fish consumption; and To explore the social and cultural importance of fish (traditional food) to the Dene...

Baseline mercury levels in predatory fish in the Sahtu Settlement Area
Principal Investigator: Guthrie, Glen H
Licenced Year(s): 2011 2010
Summary: 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...

Amendment - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2011 2010 2009
Summary: The overall objective of this research is to improve our knowledge on present-day food webs/productivity in small Arctic pond/lake systems in order to better predict changes that could occur under changing climate. The methodology described below pertains to all research activities related to this research component dealing with fish. All other research activities related to this work were revi...

Aklavik Elder's Traditional Knowledge, Climate Change and Community Health
Principal Investigator: Archie, Billy
Licenced Year(s): 2010
Summary: The goal of this research project is to gather current and traditional knowledge directly from local Elder's/Hunter's that have made observations of the climate changes experienced/observed within the last two decades, and help identify what species have benefited, or what species they think are at risk from climate change. It will validate the elder's and hunter’s knowledge and contribute to com...

Fort Good Hope baseline heavy metal accumulation in burbot (loshe) study.
Principal Investigator: Guthrie, Glen H
Licenced Year(s): 2010
Summary: This study will provide baseline data for uranium levels and contribute data to an on-going Department of Fisheries and Oceans (DFO) study that is investigating mercury levels in Fort Good Hope burbot (Loshe). Thirty fish representing three size/age classes will be collected by the Fort Good Hope (FGH) Renewable Resources Council (RRC). The samples will be sent to reputable laboratories that sp...

7 Mine Site Project
Principal Investigator: Widmeyer, Joline
Licenced Year(s): 2010
Summary: The objective of this study is to identify what fish species are in Ruth Lake and Bullmoose Lake and to conduct tissue sampling which will assist in determining if the fish in these lakes are bioaccumulating heavy metals. Fish will be sampled using techniques such as minnow trapping, seining, gill netting, angling and possibly boat electrofishing. Nets and minnow traps may be left at the sam...

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
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...
