According with MSC public report, separate stocks are currently defined in the  Atlantic sector of the Southern Ocean around South Georgia including Shag Rocks (area 48.3), South Shetland Islands (including the Elephant Island group), the South Orkney Islands and Bouvetøya. Populations within the Atlantic sector of the Southern Ocean may be genetically similar (Kuhn and Gaffney 2006), but C. gunnari has never been found in waters deeper than 700 m and most fish live shallower than 300 m, which would clearly separate South Georgia as a management unit from other populations (WG-FSA-07/12).
