Impact of ferry landings on water quality and traditional fish harvesting in the Mackenzie and Peel Rivers
Principal Investigator: Gray, Derek K
Licenced Year(s): 2018
Summary: Fishing is an important part of the Gwich’in way of life. Concerns in the Gwich’in communities of Fort McPherson and Tsiigehtchic have arisen with regards to the use of granular material in ferry landings. Anthropogenic sediment from ferry landings has the potential to alter river ecology downstream thus impacting valuable fish habitat. The objectives of this research project are to determine ...


How will fish communities in Gwich’in and Inuvialuit lakes respond to climate change?
Principal Investigator: Gray, Derek K
Licenced Year(s): 2018 2017
Summary: Purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and mediu...


Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licenced Year(s): 2017
Summary: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...
