Get To Know The Spanish Mackerel
The Spanish mackerel, Scomberomorus maculatus, is a migratory species of mackerel which are voracious, opportunistic & carnivores. As with other members of the genus, food consists mainly of small fishes with lesser quantities of shrimp and squid.
The fish exhibits a green back; its sides are silvery marked with about three rows of round to elliptical orange spots.
Spanish mackerel are similar in appearance to small King mackerel (S. Cavalla) and Cero mackerel (S. regalis). All three are very similar in shape and coloration. They may be distinguished as follows:
The lateral line on Spanish and Cero mackerel slopes gradually from the top edge of the gill to the tail. In contrast that of the king mackerel takes an abrupt drop at mid-body.
The first (spiny) dorsal on Spanish and Cero mackerel has a prominent black patch. The King mackerel has none. As all three species normally keep the first dorsal folded back in a body groove, this difference is not immediately evident.
Spanish mackerel have prominent yellow spots on the flanks at all sizes. In addition to such spots, Cero mackerel have one or more yellow stripes along the centerline. Young King mackerel have similar, but slightly smaller spots; these fade away on individuals weighing over 10 pounds (4.5 kg), but they may still be seen as spots of slightly darker green on the upper back from some angles of view.
World wide there are many members of this genus quite similar to one or another of these three species. In particular, off Mexico, Spanish mackerel may be confused with S. brasiliensis which may appear in the same area.
