Climate change means a warmer Arctic and a good reason to expand development for humankind. For salmon, climate change means moving north to cooler waters. For Arctic Inuvialuit fishers, climate change could negatively impact native species, and Inuvialuit will have to adapt to maintain their culture and ways of life.

Salmon’s Arctic Expansion Has Communities Worried

Inuvialuit fishers are adapting to rising numbers of Pacific salmon in the western Canadian Arctic, but fears remain about impacts on native species.

The first time Jody ​​Illasiak saw a salmon in one of his fishing nets was in 2017. He and a close friend were aboard a 5.5-meter Lund boat, searching for Arctic char near Lessard Creek, a well-known fishing spot near Paulatuk, Northwest Territories when Illasiak’s friend pulled up the unfamiliar fish.

Two years later, Pacific salmon were everywhere across the Inuvialuit Settlement Region (ISR) in the western Canadian Arctic. This area includes Paulatuk and five other communities where the species were once scarce. “That was the craziest year for salmon in our area,” says ​​Illasiak, a Paulatuk Hunters and Trappers Committee member.

In other parts of the world, a sudden influx of salmon might be a cause for celebration, but for the ISR communities, the fish pose problems. Their arrival shows how much climate change is altering the marine environment in the western Arctic—and how much the Inuvialuit will have to adapt to maintain their culture and ways of life.

In a 2021 study, Zander Chila, a graduate student at the University of Victoria in British Columbia, delved into the firsthand knowledge of anglers from across the region, confirming that more and more Inuvialuit are catching more and more salmon. Chila and his coauthors combined accounts from more than 50 interviews with 20-plus years of voluntary harvest data from the Arctic Salmon Project, a collaboration between Fisheries and Oceans Canada (DFO), local hunters, and trappers’ organizations, to track the numbers through time.

Anglers in the more westerly communities around the Mackenzie River delta have been catching salmon on and off for more than 60 years—likely chum salmon returning to the Mackenzie River to spawn. But the eastern communities rarely caught salmon before 1990. Then, in the mid-1990s, ISR salmon harvests—mostly chum and pink—began to rise as fish from booming Pacific Ocean populations strayed into the Arctic. In recent years, anglers in the ISR, on Alaska’s North Slope, and in the eastern Canadian Arctic continue to catch greater numbers of salmon, even though Pacific Ocean populations have declined.

Pacific salmon invasion may interact with species that the Inuvialuit relies on, including Dolly Varden [shown], and trout. The illustration of Dolly Varden [Salvelinus malma (char)] is by well know watercolorist Thom Glace.

Although scientists aren’t sure what precise impacts these fish might have on Arctic ecology, Chila says the salmon’s growing prevalence is cause for concern. In particular, salmon may interact with species that the Inuvialuit relies on, including Iqalukpik (Arctic char), anaakłiq (broad whitefish), Dolly Varden, and trout. For instance, salmon might compete for food or carry novel parasites that could harm char. By disrupting these traditional foods, salmon stands to negatively affect Inuvialuit culture and community life—a fear expressed by all of the anglers that Chila’s team interviewed.

But the harvesters also stressed their communities’ ability to adapt. For example, although Inuvialuit anglers do not target salmon, many who net the fish incidentally have put them to use. About half of the interviewees had eaten the fish they caught, and several shared their catch with community members. Even among those who are open to eating salmon, though, few know how to prepare it. In response, the Arctic Salmon Project created a cookbook in 2020 to share jerky, battered steaks, quiche, and Thai chowder recipes.

Only some people are ready to taste salmon, however. In Paulatuk, where salmon have begun showing up most recently, only one interviewee had eaten their catch. All others had returned the fish to the Arctic Salmon Project in exchange for gift cards to the grocery store.

“We’ve got no use for them,” says Illasiak

Right now, the most pressing question for Inuvialuit across the ISR is how to get salmon out of the region and prevent the fish from gaining a permanent foothold in the char habitat. A challenge is that the communities follow traditional values and governmental laws, stressing not to waste anything harvested. “If it’s a species that we’re not targeting, how do we prevent [salmon spawning] from happening without breaking the law?” asks J. D. Storr, a member of the Aklavik Hunters and Trappers Committee.

In early October, Illasiak hit upon a possible solution. He was in Vancouver, British Columbia, with Storr and DFO research scientist Karen Dunmall, who helms the Arctic Salmon Project, to present at the International Year of the Salmon symposium on the growing presence of salmon in the ISR. The trio met people from Indigenous communities along the West Coast of the United States and Canada, whose local salmon populations have declined for decades. During one conversation, Illasiak proposed catching salmon in the Arctic and shipping the fish to the West Coast.

While Illasiak admits that the community members were a little taken aback at first, interest may be there, despite the logistical challenges. As the Inuvialuit adapts to the influx of salmon, Illasiak’s idea, which finds a good use for the salmon by sharing abundance with communities in need, may be worth exploring.

In the meantime, though, communities in the ISR are working with the Arctic Salmon Project to learn how to use the salmon swimming into their region. Even with all of the uncertainties the fish represent, many Inuvialuit harvesters interviewed are optimistic that they will find a way to adapt.
