Arctic Grayling

Thymallus Arcticus - "Hulukpaugaq"

Population Status


Largely unknown although a few studies have noted the presence of grayling in lakes on the Yukon North Slope. Grayling have been recorded in Anker Creek, Babbage River, Big Fish River, Blow River, Deep Creek, Firth River, Fish Hole Creek, Malcolm River, No. 11200 Creek, Rapid Creek, Running River, Spring River and Trail River.

Population Size:


Population Trend:

Unknown. It is the opinion of native fishers on the Big Fish River that large grayling are very scarce compared to previous years.

Unique or special characteristics:


Habitat Features:




There is no restriction on the Inuvialuit harvest of Arctic grayling on the Yukon North Slope.


Yukon sport fishing regulations apply to others fishing on the Yukon North Slope. Parks Canada regulations apply within Ivvavik National Park.

The FJMC conducts a sport angler survey of recreational anglers who have purchased a licence, or registered to fish, in the ISR between April and September each year. The objective of the survey is to determine the number, species and location of fish caught by sport anglers within the ISR during the spring and summer fishing season. Anglers surveyed include those issued with a Parks Canada fishing permits to fish within Ivvavik National Park. Most sport fish catches were reported from along the Firth River corridor.


Arctic grayling attract little to no eco-tourism on the Yukon North Slope, as this species is found throughout the Yukon.

Research and Monitoring

Population Monitoring:



Some research was conducted in the early 1970s as part of Mackenzie valley pipeline studies. Information collected included distribution, length/weight relationships, and food habits.Aquatic studies were carried out in the Inuvialuit Settlement Region in 2002 as part of a feasibility study for the Mackenzie Delta Gas Opportunity. Studies have also been conducted in the area to the east of the Yukon North Slope in the Gwich’in Settlement Area.


Most aspects of Arctic Grayling ecology on the Yukon North Slope.


The Fisheries Joint Management Committee makes recommendations to the Minister of Fisheries for all fisheries matters in the Inuvialuit Settlement Region. The FJMC provides the means to jointly set Inuvialuit subsistence quota and allocate such quota among the communities.

Community-based Information

Community-based information on this species may be found in the reports of the annual community-based monitoring program conducted in Aklavik and neighbouring communities by the Arctic Borderlands Ecological Knowledge Co-op.
