Assessment of lake trout stocks in Great Bear Lake
Principal Investigator: Howland, Kimberly
Licensed Year(s): 2007 2006 2005
Summary: The objectives of this study are to: 1) gather baseline data on size and age structure, fecundity (egg number per female), growth and mortality of Dease, Smith, McVicar, McTavish, Keith arm lake trout. A different arm will be sampled each year over a 5 year time period. 2) To determine if lake trout are genetically distinct between basins. 3) To determine the extent of movements (if any) by lake t...

Shoal Habitat Utilization Study
Principal Investigator: Morrison, Scott
Licensed Year(s): 2007 2006 2005 2004
Summary: Consistent with the DFO authorization, the major objectives of the study are to provide annual documentation of shoal habitat use by Lake Trout in the vicinity of the mine site, and to ground truth hydroacoustic equipment. Study locations for 2005 are as per 2004. Hydroacoustic surveys are to be conducted during the early morning or evening hours. The survey is conducted at the same time each...

Continued Population Assessment of Harvested Fish Species in the Travaillant Lake System, Northwest Territories
Principal Investigator: Howard, Kimberly
Licensed Year(s): 2005
Summary: The main objectives of this study are to determine baseline population status and develop reliable indicators of population abundance and mortality rates of key harvested fish species (lake whitefish and broad whitefish) in the Travaillant Lake system and to identify and determine the relative abundance and species composition of other species within the lake system. Field crews will be transp...

Morphological Diversity of Lake Trout: Differentiation Between Deep and Shallow Forms
Principal Investigator: Eshenroder, Randy
Licensed Year(s): 2005
Summary: The objective of this study is to determine whether a deep-water type of lake trout resembling the “humper” of Lake Superior lives on offshore reefs in Great Slave Lake, as they do in Lake Superior. The researchers have also found humper-like trout in Great Bear Lake and in Lake Mistassini, Quebec. In Great Slave Lake, the researchers intend to target offshore reefs surrounded by deep water (deepe...

Seasonal movements of lake trout, lake whitefish and northern pike in a small northern Shield lake.
Principal Investigator: Dick, Terry A.
Licensed Year(s): 2005 2004
Summary: The objective of this research is to study what lake trout, whitefish and pike eat and their movements in a small northern Shield lake (Chitty Lake). Transportation of personnel and equipment into and out of Chitty Lake will be by single engine float plane (Air Tindi). During this study, the researchers will use standardized gill nets, a backpack electroshocker, a seine net, VEMCO acoustic tra...

Ecological Conditions in the Proposed Discharge Route of the Colomac Mine, NT
Principal Investigator: McGurk, Michael
Licensed Year(s): 2005 2004
Summary: The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...

2005 Aquatic Monitoring Program - EKATI Diamond Mine
Principal Investigator: Muggli, Deborah
Licensed Year(s): 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003
Summary: The main objective of the field work to be performed in 2005 is to determine if the EKATI mine is having an effect on its surrounding aquatic environment and to provide baseline data for the area. Transportation to and from site will be provided by BHP Billiton. The primary form of transportation of personnel and equipment will be via regularly scheduled Canadian North flights to site. While ...
