Canned tuna taste great but those other fish like sardines or herring not so much for me. Only canned fish beside tuna that like is mackerel.But I cant seem to find if this is fish is high in mercury or low in it. The cans do not say which specific species were processed.
Listed under "Least Mercury". For the most part (I believe), smaller fish = less mercury.
You may find this article insightful. As long as you are eating fish that contains more selenium than mercury, the amount of selenium in the body will always be in plentiful excess of mercury. That means that these essential selenoenzymes are never inhibited to a meaningful degree. Fortunately, the vast majority of fish most people consume have more selenium than mercury. The exceptions are pilot whale, shark, tilefish, king mackerel and swordfish.
