A dense net emerged from the turbulent Bering Sea waves, brimming with Alaska pollock tightly packed within it, their heads protruding through the mesh. When the haul spilled onto the deck, it brought along various deceased marine creatures, including a skate, crabs, jellyfish, and notably, salmon — igniting a contentious political and cultural debate surrounding industrial trawling in Alaska.
“This fishery involves capturing wild fish, so encountering unintended species is inevitable, which many find problematic,” remarked Maverick Blake, the captain of the vessel. Redirecting towards a different fishing spot to reduce salmon encounters, he emphasized the necessity of this practice in providing seafood to consumers.
Alaska pollock ranks as the world’s second-largest fishery, being a staple in U.S. McDonald’s Filet-O-Fish sandwiches and commonly utilized in fish sticks and imitation crab products. Despite employing methods aimed at minimizing environmental impacts, the nets used in pollock fishing inadvertently capture other marine species, known as bycatch.
Bycatch, referring to unintentionally caught marine life during targeted fishing operations, constitutes two percent of the pollock fishery’s overall catch. Given the massive scale of the fishery, which annually harvests billions of pounds of pollock, this translates to significant numbers of salmon, with Bering Sea trawlers capturing tens of thousands of Chinook and other salmon species each year.
The escalating tensions surrounding salmon populations in western Alaska, where Indigenous communities heavily rely on the fish, have extended to commercial and charter fishers experiencing the repercussions of declining stocks. This issue has seeped into Alaska’s political landscape, with candidates in gubernatorial and U.S. Senate races clashing over the extent of regulations needed to curb the industry’s impact.
In response to diminishing salmon populations, a seven-year ban on Chinook fishing along the Yukon River was implemented by Alaska and Canada in 2024 to facilitate population recovery. Scientists attribute the declines to warming waters and changing ocean conditions rather than trawl bycatch, citing elevated risks of salmon bycatch due to altered salmon and pollock distribution patterns.
Critics argue that while warming oceans play a significant role in salmon declines, bycatch remains a controllable factor crucial for conservation. The impact of even minimal losses is magnified when dealing with depleted fish stocks, particularly along the Yukon River, where each salmon holds immense value for local communities.
Onboard vessels, captains strive to minimize salmon bycatch, a vital aspect of their operations. Despite the challenges, industry representatives maintain that the Alaska pollock fishery is among the best-managed globally, emphasizing continuous efforts to enhance salmon avoidance measures through extensive monitoring and collaboration among fishing vessels.
The broader repercussions of trawling extend beyond salmon populations, affecting small-scale commercial fishers, charter operators, and marine habitats. The frustration stemming from shrinking catch limits and habitat damage fuels the anti-trawl sentiment, drawing diverse stakeholders together in advocating for tighter regulations to preserve dwindling fish stocks and marine ecosystems.
