Blue mackerel

Blue mackerel (Scomber australasicus), also known in some markets as english mackerel (or EMA), is a schooling small pelagic species of the Scombridae family, distributed through the Indo-West Pacific. It occurs in both coastal and oceanic waters, with commercially important concentrations around Japan, Taiwan, Australia, and New Zealand. The species is associated with temperate and subtropical waters, and its broad regional spread gives it a stable role in pelagic fisheries across both the Northwest Pacific and Australasian markets.

Blue mackerel is marketed mainly for human consumption and is sold in fresh, frozen, dried-salted, smoked, and canned forms. Its commercial appeal lies in its low oily flesh, familiar mackerel profile, and strong processing performance, which make it suitable for both whole-fish trade and value-added processing. Compared with species carrying a stronger premium image, blue mackerel is positioned as a reliable regional bycatch pelagic fish with good everyday marketability and broad end-use flexibility.

The most relevant commercial fisheries are found in Australia and New Zealand, where the species is actively managed and commercially harvested, while the wider Northwest Pacific also remains important for its supply and recognition. In practical market terms, blue mackerel belongs to the category of solid, efficient, workhorse pelagics.
