Licensed 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...

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...

Summary: The objective of this study is to collect whitefish and lake trout in the Keith Arm of Great Bear Lake near Deline and analyze tissues for metals and radionuclides. The results of this study will supplement the results of a study conducted in 2009 which reported the concentrations of metals, radionuclides and organo-chlorine pesticides in a small number of trout and herring. Twenty whitefis...

Principal Investigator: Nielsen, Jennifer L.
Licensed Year(s): 2008 2007
Summary: This study aims to: 1) use genetics and otolith (ear bone) microchemistry to determine if differences exist between collections of Arctic cisco (herring) made from tributaries of the Mackenzie River (Canada) and the Colville River (Alaska) and 2) use differences to identify population-of-origin of fish caught in the Colville River subsistence fishery. Approximately 60 Arctic cisco will be colle...

Summary: The Mackenzie Gas Pipeline will cross more than 600 tributaries of the Mackenzie River, ranging from small (< 1 m) vegetated swales to large rivers. All construction methods, with the exception of trenchless drilling, will disturb the bed and banks of the rivers they cross. Fish habitat use and distribution has not been studied in sufficient detail. Fish will be captured and identified for spec...

Principal Investigator: Howland, Kimberly
Licensed Year(s): 2007 2006 2005
Summary: The objectives of this research are: 1) to gather baseline data on size, age structure, fecundity (egg number per female), growth and mortality for lake trout in the study area; 2) to determine if lake trout are genetically distinct between basins of Great Bear Lake; and, 3) to determine the extent of movements by lake trout in Great Bear Lake by using molecular genetics. Field crews will be tr...

Licensed Year(s): 2001 2000
Summary: Transportation to and from sampling sites will be provided by helicopter. Basic camping equipment will be set up for a few days in each sampling location for sleeping and eating during sampling. All fish captured will be tagged with colored tags (floy tags) and some (2-5) with radio-tags to identify fish movement and locate spawning sites. Fish will only be sampled to collect information on dis...

Principal Investigator: Lockhart, W.L.
Licensed Year(s): 1993 1992
Summary: The researcher and his team will engage in a bathymetric survey to map the contours of the bottom of Lac Belot, as well as determine the distribution of fish in the lake. Several soil samples will be collected to determine the amount of atmospheric dust fallout. As well, tissue samples from 6 lake trout and 6 ground squirrels are to be collected to compare some aspects of their biochemistry with ...

Principal Investigator: Vigers, Gary
Licensed Year(s): 1985
Summary: To determine acute and sublethal effects of oil (natural seeps) and refinery effluent on fish in the Mackenzie River at Norman Wells. Sublethal effects will include bioaccumulation and tainting. In situ fish cages and laboratory bioassays will be utilized....

Principal Investigator: McLeod, Curtis
Licensed Year(s): 1980
Summary: To document fish use of shalllow side-channel areas or river margins and to estimate the effect of water level changes on fish habitat. Detailed physical data collection (water levels, velocity and sediment samples) will be undertaken, data will also be collected of fish and small invertebrate use of habitat....
