There are two possible genetic distinct groups, one located on the east and west coasts of Greenland, and the other from the Flemish Cap to the south of Iceland and the coast of Norway (Pampoulie et al. 2009). However, the same authors consider that further genetic analysis are required to understand golden redfish stock structure in North Atlantic. Two units are therefore assumed in the NE Atlantic region for assessment and management purposes: Iceland and Faroes grounds, West of Scotland, North of Azores, East of Greenland including Subareas V, VI, XII, and XIV (ICES, 2014a) and Barents Sea and Norwegian Sea covering Subareas I,II (ICES, 2014b).
Sebastes marinus was replaced by S. norvegicus as the taxonomic name to identify golden redfish, according to ICES (2015a).
