Habashi B.B., Kompowski A., Wojciechowski J., 1987. Food and feeding of chub mackerel, Scomber japonicus Houttuyn, 1782 in the north-west African shelf. Acta Ichthyol. Piscat. 17 (1): 77-92.
Food of the chub mackerel is very diverse; it consists of both plankton (mainly calanoids, euphausiids, and tunicates) and nekton (cephalopods and fish). The food composition varies considerably from month to month. Feeding intensity, generally rather high, decreases somewhat during spawning.
