Community-based monitoring of whitefish in the lower Mackenzie River watershed
chercheur principal: Hovel, Rachel A
Année(s) de permis: 2021 2019
Résumé: The objective of this project is to maintain a community-based monitoring program in the communities of Fort McPherson, Aklavik, and Tsiigehtchic. Data collected in this community-based monitoring program and other previous research has shown that ocean-migrating broad whitefish use the Peel River as spawning habitat, and that these fish also make extensive migrations between rivers in the lowe...


Paulatuk Whitefish Assessment
chercheur principal: Ruben, Diane
Année(s) de permis: 2017 2016
Résumé: The objectives of the research are to conduct an assessment of whitefish diet and contaminants. Two technicians will collect approximately 60 samples over 7 days at Billy’s Creek in July 2017 and an additional 60 samples at the Hornaday River in August 2017, collecting data on: species, location, date/time, catch effort/gear type, length, weight, sex, maturity, otolith, stomach content (frozen)...


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....


Contaminant analyses for wildlife food sources in the Inuvialuit Settlement Region
chercheur principal: Bell, Bob
Année(s) de permis: 1993
Résumé: This project was initiated following the concern voiced by the six ISR communities about the presence and levels of contaminants in the major country food sources. Samples of body tissues will be taken from charr, whitefish, seals and belugas in order to assess for heavy metal, organochlorine and PCB contaminants. These samples will be taken while other field research is being conducted by Fishe...


Atmospheric contaminant inputs to and impacts on Lac Belot
chercheur principal: Lockhart, W.L.
Année(s) de permis: 1993 1992
Résumé: As part of this ongoing study, sediment samples will be taken fron the deepest locations of Lac Belot and Colville Lake. These samples will be analyzed for the presence of contaminants and dated. These analyses will allow the researcher to construct histories of the input of contaminants to these lakes. In addition, lake trout, whitefish and burbot will be collected to determine what contaminan...


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....


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....


Genetic Stock Structuring/Population Dynamics of Mackenzie River Broad Whitefish
chercheur principal: Reist, James D.
Année(s) de permis: 1991
Résumé: This work is a continuation of a 3 year FJMC funded study to determine genetic stock and structure of the broad whitefish population utilized by communities of the Mackenzie River basin....
