The Atlantic Mackerel’s (Scomber scombrus) impressive range stretches from Labrador to North Carolina in the western Atlantic and from Iceland to Northern Africa in the eastern Atlantic. Populations of Atlantic Mackerel have also been found in the Baltic, Mediterranean and Black seas. Closer to home, the Atlantic Mackerel inhabits the gulf of Maine and frequent visitor to our coastal bays and inlets during the mid summer months.
Close to thirty different species, share the common name “mackerel”, a term meaning "marked" or "spotted."
The Atlantic Mackerel’s nickname originates from the 20-30 dark wavy bands, overlaying the fishes blue-green colored back. The bands run across the back, from the fish’s head to tail and stretching down the body to approximately the midline. From the midline to the fish’s belly, the coloration changes to a brilliant silvery white iridescence. The stripes at first may appear to provide camouflage but that is not the case, scientists have determined that the strips help the Atlantic Mackerel properly communicate body movements with each other while schooling and feeding.
The Atlantic Mackerel reproduces in early summer, with a majority of the spawning occurring in the Gulf of Maine during the months of June and July. Prolific broadcast spawners, females produce and distribute as many as 1,000,000 eggs that in turn receive fertilization by males. After spawning, Atlantic Mackerel do not protect their eggs and offspring; instead eggs float free in the open ocean until hatching. Juveniles feed on plankton until reaching a size where they become capable of consuming small crustaceans, fish, shrimp and squid.
Most of the Atlantic Mackerel caught in Maine waters reach an average length of around 15-16 inches and weigh approximately 2-3 pounds. A few luck anglers occasionally pull larger, trophy size Atlantic Mackerel out of Maine’s coastal waters each summer reaching a hefty 4+ pounds. A mackerel for the record books would weigh 7+pounds.
