Separate stocks of Northern prawn (P. borealis) have not been clearly defined and may represent a single metapopulation within the Northwest Atlantic. However, there are some differences that provide basis for delineating assessment and management units into Shrimp Fishery Areas (SFAs). This profile corresponds to the S Labrador & N Newfoundland assessment unit in SFAs 6. Ten other assessment units are onsidered in Canadian waters, besides three other assessment units in the NW Atlantic: Northern prawn – Western Greenland, Northern prawn – Flemish Cap and Northern prawn – Gulf of Maine.
