Mackerel (Scomber spp.) is a pelagic fish and belongs to the large family of Scombridae. Mackerel is a migratory fish and a fast traveler. The catch is therefore seasonal. Scomber scombrus (Atlantic), Scomber japonicus (Atlantic & Pacific) and Scomber australasicus (South Pacific) are amongst the most important and extensively fished. The oil content in the fish can reach up to 30% and is very rich in omega 3 acids.
