Principal Investigator: Clayton, Terry
Licensed Year(s): 1993
Summary: The researchers have been commissioned by Echo Bay Mines Ltd. to conduct a study on young-of-the-year arctic grayling which are located in a small creek near a tailings pond of the Lupin mine site. Approximately 100 hatched arctic grayling will be caught in order that contaminant analyses can be conducted on the tissues....

Principal Investigator: Fisk, Aaron
Licensed Year(s): 1993
Summary: The researcher plans to take samples of sediments and fish from sites near the three settlements in order to determine the types of contaminants that are present in the environment as well as those that collect or accumulate in the tissues of fish. This study will benefit other studies that have examined contaminants in NWT wildlife as fish are preyed upon by a variety of wildlife species. The r...

Principal Investigator: Bell, Bob
Licensed Year(s): 1993
Summary: This project was initiated following the concern voiced by the six ISR communities about the presence and levels of contaminants in the major country food sources. Samples of body tissues will be taken from charr, whitefish, seals and belugas in order to assess for heavy metal, organochlorine and PCB contaminants. These samples will be taken while other field research is being conducted by Fishe...

Principal Investigator: Stabler, Matt
Licensed Year(s): 1993
Summary: Anadromous arctic charr, currently viewed of as the eastern form, are known to spawn and overwinter in the DeSalis River system. Residents of Sachs Harbour have expressed an interest in harvesting arctic charr from this system for consumption and commercial purposes. Two resident monitors will sample the subsistence catch of this stock in order to estimate stock size and age. Whole fish will be ...

Principal Investigator: Lockhart, W.L.
Licensed Year(s): 1993 1992
Summary: As part of this ongoing study, sediment samples will be taken fron the deepest locations of Lac Belot and Colville Lake. These samples will be analyzed for the presence of contaminants and dated. These analyses will allow the researcher to construct histories of the input of contaminants to these lakes. In addition, lake trout, whitefish and burbot will be collected to determine what contaminan...

Principal Investigator: Welch, Harold
Licensed Year(s): 1993 1992 1991 1990 1988 1987
Summary: The researcher and his team will continue their marine research at Resolute. They will continue their work on the trophic dynamics of the arctic marine food chain as it pertains to marine mammal and seabird production. The main goal is to obtain data on seasonal cycles of energy flow. The team will also be examining organochlorine and heavy metal contaminants in the marine system....

Principal Investigator: Ash, Gary R.
Licensed Year(s): 1994 1993 1992
Summary: The researchers will obtain baseline water quality data for the study waterbodies, discharge information for the major streams in the study area, baseline information on fish species composition and relative abundance in the study area, and information of background levels of metals in fish tissue from selected waterbodies in the area....

Principal Investigator: Brunskill, Gregg
Licensed Year(s): 1991 1990
Summary: The Researcher and team will obtain live fish for immediate field dissection and dry ice freezing of tissue samples for contaminant, enzyme and protein measurements. Large core samples of deep lake muds are sliced into thin layers in the field for radiochemical estimation of slice age and the measurements for organochlorines, PAHs, metals and other geochemical parameters....

Principal Investigator: Smith, B.Sc., Geoffrey M.
Licensed Year(s): 1987
Summary: 1. To collect fish to obtain samples of muscle and liver tissue for heavy metal analysis; 2. To sample stream and lake habitat areas to evaluate fish species composition, density and habitat use....

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....
