Testing molecular and otolith tools to investigate population-of-origin and migration in Arctic cisco found in the Colville River, Alaska
Principal Investigator: Nielsen, Jennifer L.
Licenced Year(s): 2008 2007
Summary: This study aims to use genetic markers and otolith microchemistry to determine if differences exist between putative Arctic cisco spawning aggregations in tributaries of the Mackenzie River (Peel and Arctic Red rivers); and, if differences do exist, to use this information to identify population-of-origin for fish caught in the Colville River subsistence fishery. During the summer or fall (1 Au...


Arctic Red River Fish Study
Principal Investigator: Millar, Nathan P
Licenced Year(s): 2006
Summary: Currently, little information exists on the fisheries resources of the Arctic Red River. Baseline information on fisheries resources is required to make sound management decisions. This information (e.g., biological characteristics of fish: length, weight, age at maturity, migration patterns, date of spawning; presence/absence of species) is collected through long-term studies, traditional knowled...


Stock Delineation of Fish Species in the Mackenzie River
Principal Investigator: Millar, Nathan P
Licenced Year(s): 2006
Summary: This study involves the determination of the population structure of fish in the Mackenzie River. Specific objectives include the delineation of stocks of three fish species: loche (Lota lota), crookedback (Coregonus clupeaformis) and coney (Stenodus leucicthys), and the identification of downstream fisheries as mixed-stock or single-stock fisheries. A population genetics approach will be employed...


Shoal Habitat Utilization Study
Principal Investigator: Morrison, Scott
Licenced 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...


Seasonal movements of lake trout, lake whitefish and northern pike in a small northern Shield lake.
Principal Investigator: Dick, Terry A.
Licenced 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...


Phylogeography and Genetic Population Structure of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta and River and Surrounding Area, Northwest Territories
Principal Investigator: Harris, Les
Licenced Year(s): 2005
Summary: The objective of this study is to establish a baseline collection of tissue and fin samples from broad whitefish that will eventually be used for phylogeographic analysis and the classification of their genetic population structure. Local Gwich’in and Inuvialuit fishermen will be asked, on a volunteer-only basis, to collect fins or tissue samples from broad whitefish caught during the subsisten...


The biogeography and ecology of deepwater sculpin (Myoxocephalus thompsoni): conservation of a glacial relict
Principal Investigator: Sheldon, Tom
Licenced Year(s): 2004
Summary: The deepwater sculpin is a small species of fish found only in the deepest lakes in Canada. Its closest relative is the marine fourhorn sculpin which is distributed in shallow marine waters of the arctic North American coast. To resolve the issue of orig...


Sable and Two-Rock Lake Fish-Out
Principal Investigator: Armstrong, Allison
Licenced Year(s): 2002 2001
Summary: The objective of the fish-out is to provide scientifically defensible data to: (1) quantify fish production, fish habitat and productivity of the intermediate trophic levels (primary and secondary producers); (2) establish linkages between fish habitat and fish productivity in Sable and Two-Rock Lakes; (3) establish a reference database through which comparisons among lakes can be conducted; and (...


Collection of Silurian fishes and trilobites and articulated remains of Devonian chondrichthyans and other fishes from the Mackenzie Mountains, N.W.T.
Principal Investigator: Wilson, Mark V.H.
Licenced Year(s): 2013 1998 1996 1990
Summary: The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...


Vegetation Survey for the Ikhil Gas Development
Principal Investigator: Sutor, Greg
Licenced Year(s): 1997
Summary: Vegetation communities along the pipeline route and over other parts of the Project area would be provisionally mapped from aerial photographs. A field survey would be undertaken with an emphasis on identifying rare plants. The study area is in the Caribou Hills IBP site 4-9, which was in part proposed because of its rare flora. July is an optimum time for a single survey. Also transect sampling ...
