Monitoring of mercury, flame retardants and other chemicals in lake trout and cisco from Great Bear Lake
Principal Investigator: Evans, Marlene
Licenced Year(s): 2016 2015 2014 2013
Summary: This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. The research team require fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from Great Bear Lake. The fish will be frozen immediately after capture and shipped to Environment Canada-Saskatoon. The fish will then ...


The Continuation of a Community-led Fish Monitoring Study in Déline, NT 2012
Principal Investigator: Macdonald, Colin R
Licenced Year(s): 2012 2010 2009
Summary: To determine the levels of potential chemicals of concern in three major fish species through the analysis of muscle and liver samples for mercury, radionuclides and a number of elements. Fish of three species (lake trout, lake whitefish and lake herring) will be collected in the Keith Arm of Great Bear Lake near the community of Deline. Approximately 15 trout and 10 whitefish and 10 herring wi...


Bluefish Lake Mercury Monitoring
Principal Investigator: Dewar, David J
Licenced Year(s): 2012
Summary: The Objectives of this research project are to: 1.) gather information in 2012 on the small-bodied and Young of Year fish in Bluefish Lake that may be available for monitoring as well as determine the most suitable methods and locations for their capture in order to finalize the proposed mercury study design, and 2.) complete monitoring between 2013 and 2015 as described in the finalized mercury ...


Habitat Utilization and Fish Community Structure in the Snare River.
Principal Investigator: Reed, Shawna
Licenced 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
Licenced 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
Licenced 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
Licenced 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
Licenced 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
Licenced 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
Licenced 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....
