Puebla et al. (2008) found homogeneity on the genetic structure of queen crab along the west coast of Greenland and within Atlantic Canada from southern Labrador to Nova Scotia. Four assessment units are delimited by DFO-Canada and managed separately: Estuary and N Gulf of St Lawrence (areas 13 to 17, 12A, 12B, 12C and 16A), Newfoundland and Labrador (offshore and inshore areas of Divisions 2HJ3KLNOP4R), Nova Scotia (North and South Nova Scotia 4V,W,X) and S Gulf of St Lawrence (Areas 12, 19, 12E and 12F). Within W Greenland there are 6 management units: Upernavik, Uummannaq-Disko Bay, Sisimiut, Maniitsoq-Kangaamiut, Nuuk-Paamiut and Narsaq-Qaqortoq (Burmeister, 2010).
