Abstract

The primary objective of this study was to determine whether selected assemblages of blue swimmer crabs in nearby and more distant geographic sites in states throughout Australia are genetically differentiated and thus constitute different stocks. More specifically, the three performance indicators of this study were to: (i) determine which of the spatially-isolated assemblages of adult crabs within and among geographic regions throughout Australia are genetically distinct and should therefore be managed as separate stocks; (ii) determine whether selected assemblages within single ‘habitats’ are genetically homogeneous and thus constitute single stocks; and (iii) identify major genetic breaks, and associated ecological or geographical corrrelates (i.e. north versus south and/or east versus west), in the population structure of Portunus pelagicus.
