At almost every coast, which is inhabited by humans, mackerels are fished. Sometimes overfished. Mackerles, Makrelen, or Macarelas are distributed from the cold northern Atlantic to the tropics, from the surface to 1000 m depth, from open water to coral reefs. But it is not just one species of fish. At least 23 different species hide behind this name in different parts of the world, and in different languages. Here a small overview over the diversity of mackerels.
