Community-based monitoring of whitefish in the lower Mackenzie River watershed
chercheur principal: Hovel, Rachel A
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.5062. The two primary objectives are to: 1) maintain a community-based monitoring program of luk dagaii (broad whitefish, Coregonus nasus; herein referred to as whitefish) in the Peel River watershed, based in the communities of Fort McPherson, Aklavik, and Tsiigehtchic. Specifically, the research team measure fundamental b...


Seasonal movements of lake trout, lake whitefish and northern pike in a small northern Shield lake.
chercheur principal: Dick, Terry A.
Année(s) de permis: 2005 2004
Résumé: 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
chercheur principal: McGurk, Michael
Année(s) de permis: 2005 2004
Résumé: 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...


Phylogeography and Genetic Population Structure of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta and River and Surrounding Area, Northwest Territories
chercheur principal: Harris, Les
Année(s) de permis: 2005
Résumé: 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...


Broad whitefish population study and traditional knowledge
chercheur principal: Tallman, Ross F
Année(s) de permis: 1993 1992
Résumé: The researchers will work with other scientists to examine the broad whitefish of the Mackenzie River and associated tributaries of the Arctic Red and Peel Rivers. Features such as population size, migration, growth, age of sexual maturity and mortality will be examined. A study of the traditional knowledge of broad whitefish and fishing in the Mackenzie River will also be developed. Training i...


Broad whitefish tagging project
chercheur principal: Babaluk, John
Année(s) de permis: 1993 1992
Résumé: The researchers will tag broad whitefish in the Mackenzie River Delta in the vicinity of Horseshoe Bend. During this season, fish are moving to areas further upstream. Tagging will provide information about the movements, growth, survival and numbers of whitefish and will contribute to their management. Local residents will take part in a training program on the methods of tagging fish....


Radio tagging of broad whitefish (Coregonus nasus) on the Arctic Red River
chercheur principal: Chang-Kue, Ken T.J.
Année(s) de permis: 1993
Résumé: The field work of this project will involve attaching radio tags or transmitters on 20 broad whitefish at a location approximately 40 km from the mouth of the Arctic Red River. The movements of these whitefish from September to the following June can then be monitored to determine their migration routes, spawning areas and overwintering areas. Data from the radio transmitters is collected by a s...


Genetic population structuring of Mackenzie River broad whitefish
chercheur principal: Johnson, Jim
Année(s) de permis: 1992
Résumé: Mackenzie River basin broad whitefish represent a mixed-stock population which utilizes different geographical areas for different stages of its life history. The study will examine the role of outer delta lakes and lakes/rivers of the Tuktoyaktuk Peninsula in the life history of the Mackenzie River population....


The Broad Whitefish Traditional Knowledge Ecological Study
chercheur principal: Freeman, Milton M.R.
Année(s) de permis: 1994 1993 1992
Résumé: Under the direction of the Aklavik and Inuvik HTA's, the research team will carry out interviews with Inuvialuit that are knowledgable about the broad whitefish and its fishery in the local waters. Data to be obtained include information on the traditional fishery, changes to this fishery, knowledge about the breeding and feeding habits, migrations, parasites and diseases, and effects of local en...


Hydroacoustic Survey of Migratory Coregonids in the Arctic Red River
chercheur principal: Chiperzak, Doug
Année(s) de permis: 1992
Résumé: The researchers will conduct a mobile hydroacoustic survey from a 20 ft. boat using a BioSonics dual-beam echo-sounder and recording system. A limited amount of gillnetting will be conducted to provide groundtruthing information for the acoustic data. Target strength analysis will also be conducted....
