The Okhotsk Atka mackerel (Pleurogrammus azonus), also known as the Arabesque greenling, is a mackerel-like species in the family Hexagrammidae.

[1] The Okhotsk atka mackerel was first formally described in 1913 by the American ichthyologists David Starr Jordan and Charles William Metz with its type locality given as Nampo in North Korea.

[1] The juvenile Okhotsk atka mackerel gather in large schools close the surface but the adults are benthic.

The females lay egg masses within crevices or in gravel along rocky coasts at depths of less than 20 m (66 ft), these are guarded by the males.

The Okhotsk atka mackerel is an important fish, and approximately 100,000 tons of the species were harvested each year throughout the late 20th century.
