Estimating Aquatic Species Physiological Limits (ASPL) through a Forage Fish Monitoring and Observation (FFMO) program in the Inuvialuit Settlement Region (ISR)
chercheur principal: Steiner, Nadja
Année(s) de permis: 2021 2019
Résumé: This licence has been issued for the scientific research application No.4554. The 3 year project objective is to conduct underwater eco-physiological monitoring in remote Inuvialuit coastal areas in both summer and winter seasons. This will result in critical benchmark data with emphasis on coastal forage fish species during rapid climate change. Another project off-shoot will be a self-suffici...


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 2016 and an additional 60 samples at the Hornaday River in August and October 2016. Data will be collected on: species, location, date/time, catch-effort/gear type, length, weight, sex, maturity, otolith, stom...

chercheur principal: Low, George
Année(s) de permis: 2016 2015 2014 2012 2011
Résumé: The objectives of this project are: 1) To determine which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes using Traditional Knowledge. 2) To train community monitors to collect fish and other samples according to Environment Canada and Department of Fisheries and Oceans protocol. 3) To involve local school children i...


Monitoring of mercury, flame retardants and other chemicals in lake trout and cisco from Great Bear Lake
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2016 2015 2014 2013
Résumé: This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. The research team require a batch of spring-caught fish and a batch of summer/fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from each collection period. The fish will be frozen immediately after capture and s...

Effects of Athabasca and Slave River Sediments affected by oil sands operations on embryonic fish
chercheur principal: Jones, Paul D
Année(s) de permis: 2013 2012 2011
Résumé: The research team will quantify the effects of exposure of embryonic fish to contaminants released from oilsands operations that may be present in the sediments. The research team will drill a hole in the ice, no more than 12 inches in diameter, and use sediment collection equipment to collect a few centimeters of sediment from the river bed. Local communities will have an opportunity to as...
