June 17, 2026 – For Alaskans, fishing isn’t a hobby — it’s part of the fabric of our state. It is culture, economy, and subsistence. Reasonable people have long disagreed on how best to manage Alaska’s fisheries, but skepticism should be rooted in data. The data on pollock bycatch tells a story rarely seen in the headlines, in campaign rhetoric and social media accounts.
In 2025, pollock fishing vessels encountered 32,920 Chinook salmon while harvesting more than 3.1 billion pounds of pollock — one Chinook for every 95,654 pounds caught. All Alaskan trawl vessels combined encountered 38,953 Chinook across 4.2 billion pounds of groundfish, or one Chinook per 106,706 pounds. These figures come from federal observers and electronic monitoring with 100 percent trip coverage — not industry self-reporting. (Source: NMFS BSAI and GOA Salmon Bycatch Data, 2025)
Critically, the majority of these Chinook are not from Alaska. In 2023 only 45.58 percent of Chinook encountered by Alaska pollock vessels were of Alaska origin. Of those Alaska-origin fish, just 31 came from the Upper Yukon — 0.10 percent of all Chinook bycatch. Coastal Western Alaska rivers accounted for 5,607, Southcentral rivers for 1,745, while British Columbia and West Coast U.S. stocks made up more than 54 percent of the total.

Looking at total Chinook fishing mortality across Alaska, using 2024 government data, provides even more context on who is responsible for Chinook mortality:
- Commercial salmon fisheries: 53 percent
- Sport and personal use fisheries: 24 percent
- Subsistence: 14 percent
- All trawl bycatch (pollock and non-pollock): 9.06 percent
- Eastern Bering Sea pollock bycatch alone: 1.9 percent (Source: ADF&G/ NMFS BSAI and GOA Salmon Bycatch Data, 2024)
Regionally, pollock bycatch accounts for just 1.75 percent of total Chinook fishing mortality in Southcentral rivers, 0.72 percent in Southeast rivers, and 0.93 percent across all Gulf of Alaska rivers. In most Alaska rivers the impact of pollock fishing on Chinook returns is less than one percent — not enough to crash a fishery.
A similar story emerges for chum salmon bycatch. Data on hatchery releases reveals that a majority of chum salmon encountered are of Asian and Russian hatchery origin. Russia has explicitly stated its intention to double its hatchery production — flooding the ocean with more hatchery fish which will inevitably show up in bycatch numbers.
The accompanying chart illustrates dramatic changes in chum salmon hatchery releases from 1994 to 2023 (Source: NOAA). Russia’s production has surged over 500%, dwarfing contributions from South Korea, Japan, and Canada. This international hatchery expansion significantly contributes to chum salmon abundance in the North Pacific, meaning much of the bycatch attributed to Alaskan fisheries is from foreign hatchery sources. It’s well known that the hatchery fish are released when they are larger and older than natural Alaskan stocks. This places the natural stocks at a serious disadvantage when competing for limited food sources.
Pollock trawl bycatch itself is also often misrepresented. According to NOAA’s 2025 bycatch and discards data, squid and jellyfish account for more than 61 percent of all pollock fishery discards. These are non-target, non-managed species with no conservation concern. The salmon and halibut that dominate public debate represent only a small fraction of total bycatch. (Source: NOAA Bycatch and Discards in Alaska Pollock Fisheries, 2025)
Claims that commercial fishing operates without oversight are false. Federal law requires independent observer coverage or electronic monitoring on virtually every pollock trawl trip. Those Chinook encountered are counted and genetically sampled by federally employed workers. The numbers in this piece come directly from that mandatory federal system — the same data used by NOAA and the North Pacific Fishery Management Council to set policy.
Alaska’s seafood industry supports over 48,000 direct jobs and $2.5 billion in US economic activity. The pollock industry annually returns $80-$100 million dollars to 65 Western Alaska villages, accounting for 6300+ Alaska jobs, generates $832 million dollars in Alaska economic activity and $21 million dollars in taxes for state and local governments. The pollock fishery is the backbone of Alaska’s fishing industry.
Hyperbole from candidates, NGOs, Facebook groups, and outside interests should not drive fisheries management.
Facts, science, and data should.
Alaska’s fisheries are too important — economically, culturally, and ecologically — to be managed on incomplete information. Alaskans deserve a factual debate.
