Mackerel is a common name given to a number of species of fish. Most mackerel are from the Scombridae family.
Some species of mackerel migrate
for long distances along the coast and other species cross oceans
They are pelagic fish, found in both temperate and tropical seas. Most live along the coast or offshore in the oceanic environment.
Mackerel typically have vertical stripes on their backs and deeply forked tails. They are superb swimmers, but are often eaten by larger predators such as cod, sharks and dolphins.
Mackerel is an oily fish with rich of omega-3. The flesh of mackerel spoils easily, especially in the tropics, and can cause food poisoning. So, it should be eaten on the day of capture, unless pickled in salt, or refrigerated.
