Scomber australasicus is found in the Red Sea and the nothern Indian Ocean, its distribution overlaps with that of Scomber japonicus.
A coastal pelagic species, to a lesser extent epipelagic to mesopelagic over the continental slope.
Schooling by size is well developed and initiates at approximately 3 cm; may also form schools with Sarda chiliensis, Trachurus symmetricus and Sardinops sagax.
Adults stay near the bottom during the day; go up to the open water at night, where they feed on copepods and other crustaceans, fishes and squids.
They spawn in batches. Eggs and larvae are pelagic.
In Asian waters, they move to deeper water and remain inactive during the winter season. Commercially cultured in Japan.
