The yellowtail horse mackerel (Trachurus novaezelandiae), also known as the yellowtail scad, is a jack in the family Carangidae found around Australia and New Zealand at depths to 500 m. Its length is up to 50 centimetres (20 in). The yellowtail scad is the only member of the monotypic genus Atule and is distinguished from similar species by a well-developed adipose eyelid and finlet-like extensions of the last rays of the dorsal and anal fins. It inhabits coastal areas such as bays and coral reefs, preying on small fishes and crustaceans. The yellowtail scad is an important component of fisheries throughout its range, taken by a number of netting and hook-and-line methods. It is a prized food fish in some regions and is cooked or preserved by a variety of methods.
