Mackerel scad western Indian, and the North west, center west, center east and south west Pacific. Mackerel scad usually live in subtropical seas at depths up to 400 m. They prefer clear water, and are frequently found around islands. Although mackerel scad have been found at the surface, they are usually caught at depths between 40 and 200 meters. They feed mainly on zooplankton. Mackerel scad are fairly important both to fisheries and to sportfishing.
