Morphological Diversity of Lake Trout: Differentiation Between Deep and Shallow Forms
Principal Investigator: Eshenroder, Randy
Licenced 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...

Tuktoyaktuk Lake and Fish Habitat Survey
Principal Investigator: Jalkotzy, Peter
Licenced Year(s): 2001 2000
Summary: The research team will conduct a lake and fish habitat survey, to identify which water bodies have the following characteristics: overwintering fish, lake depths greater than 3.5 feet and water quality conditions which are not suitable for overwintering fish. The research team will consist of 3 crews, 4 men/crew. Crews will receive their safety and sampling orientation in Tuktoyaktuk Harbour at ...

Implications of climatic change on water-based recreational activities in Nahanni and Jasper National Parks
Principal Investigator: Staple, Tamara
Licenced Year(s): 1993
Summary: The research in Nahanni National Park includes the setting up of programs to monitor water depth and vegetational changes along the river. Changes in water depth influence the ability of navigating the river, especially in areas of rapids, and has implications on the level of expertise required by visitors travelling the river. Monitoring vegetation along the river will provide information about...

Monitoring Movements and Dive Habits of Bowhead Whales Through Satellite Monitoried Radio Tags
Principal Investigator: Mate, Bruce R.
Licenced Year(s): 1992 1991
Summary: The Researchers will once again attempt to tag 12 bowhead whales. They will study how the whales move about during the feeding season and where and when they migrate west out of the Beaufort Sea. They will determine whether the migratory routes or timing vary between different kinds of animals and will determine the dive habits of the tagged animals....

Licence #2661
Principal Investigator: McLeod, Curtis
Licenced Year(s): 1981
Summary: To document fish use of shallow side channel areas or river margins to estimate the effect of water level changes on fish habitat. Detailed physical data collection (water levels, velocity and sediment samples) will be undertaken, data will also be collected of fish and small invertebrate use of habitat....
