Tag: Mackerel mercury

Data shows that mercury concentration in fish is heavily influenced by species, size, and age. The question of what has more mercury, tuna or mackerel, has a nuanced answer that depends on which specific fish you are referring to, from King mackerel to canned light tuna.

With mercury levels varying significantly even within the same species, the question of whether mackerel or tuna has less mercury depends heavily on the specific type of fish you're choosing. In general, smaller, short-lived fish contain less mercury than larger, predatory ones due to bioaccumulation up the food chain.
