Ecological Assessment Field Work for Lue Túé Sulái (the Five Fish Lakes) Candidate Cultural Conservation Area
Principal Investigator: Haas, Claudia A
Licenced Year(s): 2012 2011
Summary: This project is to fill gaps in ecological information on a Candidate Protected Area while it makes its way through the NWT Protected Areas Strategy (PAS) process. This information will be used by the working group to make recommendations on final boundary and management planning for the area. The study will be done at the same time as a study on mercury in fish being conducted by the Dehcho F...


Loche Liver Study
Principal Investigator: Thompson, Amy L
Licenced Year(s): 2008 2007
Summary: This licence is being issued for the scientific research application # 778. This research will examine the livers of Loche fish in the GSA. This research will be completed through: 1) field collection of loche in each of the GSA communities; 2) biological sampling of loche; 3) analysis of stomach health and aging (using isotopes). More specifically, biological measurements will be taken for ea...


Rat River Char Traditional Knowledge
Principal Investigator: Millar, Nathan P
Licenced Year(s): 2007
Summary: The objectives of the study are to document traditional ecological knowledge of Rat River char. Specifically, the researcher will be asking questions about: catch of char; biology of char (e.g., spawning, migration); fishing practices; fishing at the Rat River fish hole; observations on the land related to char; changes in the environment related to char; char predators - concerns and observations...


2007 Field Monitoring - Matthews Lake and Area Fish Habitat Restoration and Enhancement Project
Principal Investigator: Van Humbeck, Joe
Licenced Year(s): 2007
Summary: The objective of the 2007 portion of the project is to monitor control sites and treatment sites, and collect information on the habitat utilization. Data collected will be used to evaluate the continued success and effectiveness of the habitat construction and enhancement. Field crews will fly to Matthews Lake, landing either on the runway or the lake. The Treeline Lodge, where the research te...


Morphological Diversity in Lake Trout within Large North American Lakes: Effects of Lake Physiography on Differentiation between Deep and Shallow Forms
Principal Investigator: Eschenroder, Randy
Licenced Year(s): 2002
Summary: The immediate objective of the research is to determine whether unique morphotypes of lake trout exist in Great Slave Lake. The long term objective is to determine the distribution and ecology of unique morphotypes in North America. By studying Great Sla...
