Assessment models for Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 SSRU 88.2E for the years 2002–03 to 2010–11
Abstract: We provide an update of the Bayesian sex and age structured population stock assessment ... model for Antarctic toothfish (Dissostichus mawsoni) in the SSRU 88.2E, using revised catch, catch-at ... -age and tag-recapture data from selected trips and all vessel trips. The 2011 reference case model ... resulted in a 30% higher estimate of initial biomass than for the 2009 base case. The main reason for this ...
