Habitat Features



Little to no harvest of Lake Trout occurs on the Yukon North Slope. From 1988 to 1999 Inuvialuit harvest data for lake trout was collected through the Inuvialuit Harvest Study. There is no restriction on the Inuvialuit harvest of Lake Trout 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.

Some research conducted in the early 1970s as part of the Mackenzie valley pipeline studies. Information collected included limited distribution data, length/weight relationships and food habits.
