Habitat Utilization and Fish Community Structure in the Snare River.
Principal Investigator: Reed, Shawna
Licensed Year(s): 1994
Summary: In this study fish presence/absence and/or densities will be obtained by electrofishing representative habitat and the setting of baited minnow traps. When these two methods are not practical gill nets, trap nets, and/or beach seines will be employed. Each fish caught will be identified, measured, sexed and condition will be noted. Ten specimens of each species from each site (up to 10) will be...


Environmental Studies of the Aquatic Resources in the Prairie Creek Area.
Principal Investigator: Reed, Shawna
Licensed Year(s): 1994
Summary: In project area creeks & streams, fish presence/absence and/ or densities will be obtained by electrofishing representative habitat & the setting of baited minnow traps. Each fish caught will be identified, measured, weighed & sexed, & condition will be noted. Furthermore, in order to assess background tissue metal levels, ten specimens of each species must be sacrificed in order to obtain the req...


Environmental Study of the Aquatic Resources of the Thonokeid Lake Area
Principal Investigator: Couture, Richard
Licensed Year(s): 1994 1994 1993
Summary: Rescan Environmental Services Ltd. will continue their study on the types of fish and other aquatic organisms found in the Thonokeid Lake area. Data on species type as well as their age, abundance and habitat will be collected. In addition, muscle and liver tissue of fish will be collected in order to assess for the presence of heavy metal contaminants. This study will be summarized in an envir...


Metabolism of arctic fish and invertebrates
Principal Investigator: Gerrits, Martin
Licensed Year(s): 1994
Summary: The researchers are interested in understanding how prolonged cold conditions and reduced food availability in winter affect char. Sea-run char must increase their fat levels so that they have enough energy stored for overwintering and reproduction. Research activities will also include collecting fish and invertebrate specimens to make comparisons about cold tolerance and diet of these specimen...


Environmental study of the aquatic resources in the Spyder Lake area
Principal Investigator: Couture, Richard
Licensed Year(s): 1993
Summary: The researchers of Rescan have been contracted by B.H.P. Minerals Canada Ltd. to conduct an assessment of the types of fish and other aquatic organisms that are found in the Spyder Lake area. Tissue samples will be collected in order to assess heavy metal contaminants in fish. An environmental report will be submitted to the Territorial Government on the results of this study....


Contaminants study on fish of the Contwoyto Lake area
Principal Investigator: Clayton, Terry
Licensed Year(s): 1993
Summary: The researcher has been commissioned by Echo Bay Mines Ltd. to conduct an assessment of heavy metal contaminants in the fish of Contwoyto and Concession Lakes. Most of the study will concentrate on contaminants in lake trout but analyses will be performed on the tissues of other fish species that are caught. The study will be based out of the Lupin Mine site at Contwoyto Lake....


Banks Island fish population/charr genetic variation project
Principal Investigator: Babaluk, John
Licensed Year(s): 1994 1993
Summary: Fish populations in Fish and Raddi Lakes, located in the vicinity of Sachs Harbour, will be surveyed to determine their population characteristics. In addition, arctic charr will be collected for genetic analyses and assessment of physical differences in charr of the region. Tissue samples will be collected for future contaminant studies....


Genetics and postglacial dispersal of lake trout (Salvelinus namaycush) and arctic charr (S. alpinus) in the western arctic
Principal Investigator: Wilson, Chris C.
Licensed Year(s): 1993 1992 1991 1990
Summary: The researcher will be collecting lake trout and/or arctic charr from lakes in the vicinities of Hay River, Inuvik, Paulatuk and Tuktoyaktuk in order to examine the distributions of these species. Samples of liver and muscle tissue will be collected from these fish for genetic analyses: this research will provide information about how different populations are related to each other (i.e., their o...


Investigation of the nervous and immune systems in the beluga
Principal Investigator: Romano, Tracy
Licensed Year(s): 1993
Summary: This research will examine the nervous (i.e., brain) and immune systems of beluga by collecting these tissues from harvested animals for laboratory analyses. This study will help to determine how contaminants affect the health of belugas. In addition, the data collected may lead to a better understanding of why whales strand themselves on the shoreline as it has been suggested that beached whale...


Congener Patterns of Contaminants in Fish and Sediments of the Mackenzie River Basin
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...
