Understanding the 'Cleanliness' of Fish
When considering if a fish is "clean," several factors are evaluated: the level of contaminants, the sustainability of the fishery, and the environmental impact of its harvest. For Alaska pollock, which primarily comes from the wild, the assessment is overwhelmingly positive due to the cold, remote waters it inhabits and the stringent management of its fishery. The following sections break down why this species is an excellent choice for a healthy and responsible diet.
Low Mercury Content and High Nutrition
One of the most significant concerns for seafood consumers is mercury contamination. As a smaller, short-lived fish, wild Alaska pollock has a very low risk of mercury contamination, making it a safe option for frequent consumption, even for pregnant women and children. The FDA and the state of Alaska have performed extensive testing, confirming the lack of detectable mercury levels in many samples.
Beyond its low mercury profile, Alaska pollock is a nutritional powerhouse. It is a lean, white fish, packed with high-quality protein, vitamin B12, and essential omega-3 fatty acids. A 3-ounce serving can provide over 130% of the recommended daily amount of vitamin B12 and significant amounts of protein with low calories and fat.
Sustainable Fishery Practices
Wild Alaska Pollock is recognized as one of the world's most sustainably managed fisheries. It holds certifications from organizations like the Marine Stewardship Council (MSC) and the Alaska Responsible Fisheries Management program. Regulations by NOAA Fisheries and the North Pacific Fishery Management Council ensure the long-term health of both the fish population and the marine ecosystem. Key indicators include healthy fish stocks, minimal bycatch through specialized gear, a science-based ecosystem approach, and a relatively low carbon footprint.
Minimal Environmental Pollution
Due to its relatively short lifespan and feeding habits in cold, remote waters, wild Alaska pollock is exposed to lower levels of contaminants like mercury and potential microplastics compared to larger, longer-living predatory species. While a 2023 study did detect microplastics in some samples from the Bering Sea, particularly in older fish, management efforts aim to mitigate pollution. Its wild nature also means it avoids antibiotics and pesticides.
A Comparison: Alaska Pollock vs. Atlantic Cod
Comparing Alaska pollock with Atlantic cod highlights characteristics of a clean fish. Both are good choices, but they differ in aspects like mercury levels and sourcing methods.
| Feature | Wild Alaska Pollock | Atlantic Cod |
|---|---|---|
| Mercury Levels | Very low, safe for regular consumption. | Low-to-moderate; some advised to limit intake. |
| Sustainability | Highly sustainable, MSC/RFM certified. | Varies; some fisheries overfished; check source. |
| Habitat | Wild-caught, North Pacific's cold waters. | Wild-caught, North Atlantic; also farmed. |
| Texture | Fine, delicate flakes. | Firmer, robust flakes. |
| Best For | Fish sticks, tacos, stir-fries. | Fish and chips, stews, baked dishes. |
Conclusion: Is Alaska pollock a clean fish? Absolutely.
Based on its low mercury, minimal pollutant exposure from its habitat, and highly sustainable wild fishery, Alaska pollock is confirmed as a clean, healthy, and responsible seafood choice. Choosing sustainably sourced Alaska pollock provides a high-quality protein beneficial for both personal health and the environment.

Frequently Asked Questions
Q: What makes Alaska pollock so low in mercury? A: As a smaller, shorter-lived fish, Alaska pollock accumulates less mercury than larger, longer-living predatory fish.
Q: Is wild-caught Alaska pollock better than farmed fish? A: Wild-caught Alaska pollock from its natural habitat avoids potential antibiotics and contaminants sometimes linked to farmed fish.
Q: Is Alaska pollock fish sustainably harvested? A: Yes, the fishery is highly sustainable, certified by MSC, and managed with strict regulations to prevent overfishing and minimize impact.
Q: How does Alaska pollock compare nutritionally to other white fish? A: It's similar to other white fish: low fat/calories, high in protein, plus good levels of B12 and omega-3s.
Q: Is it safe for pregnant women to eat Alaska pollock? A: Yes, its very low mercury level makes it a safe option within recommended seafood consumption guidelines.
Q: Does eating Alaska pollock contribute to overfishing? A: No, populations are carefully monitored and managed by NOAA and regional councils to prevent overfishing and ensure long-term health.
Q: Can I find wild-caught Alaska pollock year-round? A: While fresh pollock is seasonal, it is available frozen throughout the year.
