The fish smoking over poles in Labrador, puts me in mind of the Innu.
Lot of people, especially on the coast, smoke fish. Preferred wood is actually blackberry bush sod. Book name for blackberry is crowberry. It grows in more barren areas. Can't get enough of that stuff when smoked with blackberry bush.
A lot of people don't know why smoking evolved back in the day somewhere on the planet. That smoked stuff tastes good is secondary. The smoke was originally to keep the flies away until the fish or meat dried enough to keep long term.
Can tell u more about the people. Labrador West, away from the coast, is mostly big iron ore mines and big hydro electric production too. About 12,000 people over that way. The coast has another 8,000 spread along a over 1000 miles of coast line. The fishery and, originally the Inuit people, live there. Destruction of the seal skin market (there are over 8 million harp seals + other types passing the coast every year) has really hurt people especially the further north you go. Naturally less other species to fish as you go north and so the impact of the loss of the seal market has been particularly devastating especially on the Inuit. Odd thing is the antis are the ones with the blood on their hands. Lot of suicide the further north you go the same as in many other Inuit areas of the world. They destroyed "an important purpose" part of people's lives.
Innu people you mention are inland people that traditionally summered on the coast. Central Labrador has about 10,000 people at the end of a 120 mile bay in from the salt water. Traditional people always lived there but WWII saw the Goose Bay air base built and still working for NATO purposes.
