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 ...


Diavik Palatability and Tissue Chemistry
Principal Investigator: Moore, Kristin M
Licenced Year(s): 2012 2009 2003
Summary: The primary objective of the 2012 program is to obtain feedback from community members relating to Lac de Gras lake trout (Salvelinus namaycush) taste, texture, general condition and health. A secondary objective is to meet requirements set out in the Fisheries Authorization for Works or Undertaking Affecting Fish Habitat. Fish collection will primarily be conducted using nets set out on...

Principal Investigator: MacNeill, Scott W
Licenced Year(s): 2003
Summary: This 5-day sampling program will involve fisheries, aquatic, and vegetation studies at/in the vicinity of the abandoned Port Radium Mine site. Concentrations of five biologically significant metals (antimony, arsenic, lead, nickel and zinc) will be dete...


Fisheries Studies For 2002 Aquatic Effects Monitoring Program
Principal Investigator: Landry, Francois
Licenced Year(s): 2002
Summary: The field work is intended to provide baseline fisheries data for four lakes (Horseshoe, Toss, Fay and Logan) and to obtain post-baseline fisheries data on eight lakes (Vulture, Kodiak, Nema, Cujo, Nanuq, Counts, and Slipper) within the Ekati claimblock...


2001 Baseline Slimy Sculpin/Lake Trout Habitat Utilization Studies
Principal Investigator: Madsen, Eric
Licenced Year(s): 2001 2000
Summary: The objective of this study is two fold: a) to collect slimy sculpin tissue samples for baseline metal analysis; b) to monitor seasonal lake trout habitat utilization in Lac de Gras using radio telemetry methodologies. Twenty-five Slimy sculpins will be collected using baited minnow traps and opportunistic underwater netting, using professional SCUBA divers if available. Samples will be sent to ap...


Metal Levels in Fish from Lakes in the Dogrib Region Surrounding Rae Lakes
Principal Investigator: Stoddart, Melissa
Licenced Year(s): 2000
Summary: This project developed out of the community concern's about the effect that local contaminants may have on their health and well being. The objectives of the study are: to obtain baseline data on the level of metals in fish from lakes that are commonly used as traditional harvesting grounds; to deliver the results of the study to the community and address local contaminant concerns; to provide co...


Water, Sediment and Fish Testing of Marian River system
Principal Investigator: Nevitt, Zabey
Licenced Year(s): 1999 1998
Summary: For many years the Dogrib have trapped and fished in and around the Marian River. There are concerns that contaminants are entering the river system. Some of the concerns include: effects on health from eating fish and effects on heath from drinking water. Field collection will take place over two days. The team will travel by canoe from Rae. Seven fish will be caught by members of the community f...


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...
