What combination of traits perfectly describes a fish likely to be high in mercury, fitting the King Mackerel profile?
Answer
Large, long-lived, and eats other fish
A helpful rule of thumb for quickly assessing mercury risk involves three key indicators related to the fish's ecological role and longevity. Fish that are large in size, have inhabited the water body for a long duration (long-lived), and primarily sustain themselves by consuming other fish (predatory diet) tend to have the highest concentrations of accumulated methylmercury. King Mackerel fits this description perfectly, contrasting sharply with smaller species like shrimp or pollock.
