Horn River Creel Survey and Stock Study
chercheur principal: Low, George
Année(s) de permis: 2018 2017
Résumé: It is the objective of this project to collect information on the walleye population from the Horn River which can be used for managing the fishery and possibly changing the regulations. In order to reach this objective the following goals have been set out: 1. to collect population structure and spawning information by setting gill nets of varying mesh size and biologically sampling a portion of...

Sanguez Lake Fish Down Study
chercheur principal: Low, George
Année(s) de permis: 2021 2019 2018 2017
Résumé: Objectives of this research are to: 1. establish a population estimate of walleye in Sanguez Lake; 2. establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3. reduce the number of walleye and pike adults such that predation on walleye recruits decreases...

Enhancement and monitoring of arctic grayling spawning habitat at Providence Creek, NWT
chercheur principal: Low, George
Année(s) de permis: 2016 2015 2014
Résumé: The primary objective of this project is to enhance Providence Creek to increase arctic grayling (Thymallus arcticus) spawning habitat. This will be done by removing beaver dams which have been shown to decrease usable spawning habitat, and to create new spawning habitat with gravel and boulders. Another objective of the project is to monitor the arctic grayling population to determine if the ...

Updating data on mercury levels in food fish species in lakes used by Dehcho communities
chercheur principal: Low, George
Année(s) de permis: 2016 2015 2014 2012 2011
Résumé: The objectives of this research project are to: 1) Determine through “Traditional Knowledge” which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes 2) Train community monitors to collect fish and other samples according to Environment Canada and DFO protocol 3) Involve local school children in our studies by arranging...
