Preliminary examination of otolith microchemistry to determine stock structure in Antarctic toothfish (Dissostichus mawsoni) between SSRU 88.1C and 88.2H
CCAMLR SSRUs 88.1C (Ross Sea) and 88.2H (Amundsen Sea), could be differentiated by the trace elemental ... concentrations in the otolith edge and then to (ii) assess the potential of natal signatures to distinguish ... stocks among these regions. For the elements (Mg, Al and Sr) spatial variation in otolith chemistry was ... shown. This resulted in the correct classification of 63% of fish overall to their original capture ...
