Atka Mackerel or Northern Atka Mackerel. To at least 54 cm ( 21.3 in ) TL (Robert Lauth, pers. comm to M.L.). Sea of Japan ( Antonenko et al. 2003 ) and Sea of Okhotsk ( Chereshnev and Nazarkin 2004 ) to Commander–Aleutian chain, and northern Bering Sea (Mecklenburg et al. 2002) to Bering Strait ( Mecklenburg et al. 2011 ) to Redondo Beach, southern California ( Eschmeyer and Herald 1983 ); rare in eastern North Pacific south of Alaska (Mecklenburg et al. 2002). Depth: lower intertidal to 720 m ( 2,362 ft ) ( Hoff and Britt 2003 ). However, this latter is a record from a trawl-caught fish that might have been taken in midwater. Following Mecklenburg and Eschmeyer (2003) , we treat Pleurogrammus azonus Jordan & Metz, 1913, a western Pacific form sometimes classified as a junior synonym of P. monopterygius (e.g., Nelson 1994 , Mecklenburg et al. 2002), as a distinct species with common name Southern Atka Mackerel or Arabesque Greenling. Molecular evidence recently presented by Crow et al. (2004) supports the existence of two distinct species.
