There is a large variation in the mercury levels found in mackerel. These levels differ markedly for different species, and even for the same species in different locations; however, the strongest positive correlation seems to be connected to the species' size (the larger species being higher on the food chain).

Species of fish that are long-lived and high on the food chain, such as marlin, tuna, shark, swordfish, king mackerel and tilefish contain higher concentrations of mercury than others.
