Why does Alaska Pollock generally exhibit a relatively low mercury concentration compared to shark or swordfish?
Answer
Because pollock are smaller and generally managed through sustainable, well-regulated harvests
The risk of heavy metal accumulation, specifically mercury, is directly linked to a fish's size, age, and position at the top of the food chain. Larger, predatory, and longer-lived species like shark or swordfish accumulate mercury over time through a process called bioaccumulation. Alaska Pollock, being naturally smaller fish, do not live long enough or occupy a high enough trophic level to concentrate significant amounts of mercury. This lower accumulation risk is further bolstered by the fact that the Alaskan fishery operates under rigorous, science-based regulations which promote long-term health sustainability for the stock.
