4. Assessment models for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea including data from the 2006/07 season

   Abstract:  We provide an update of the Bayesian sex and age structured population stock assessment ... model for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea (Subareas 88.1 and SSRUs 88.2A–B ... ), using revised catch, catch-at-age, and tag-recapture data for the 2007 season. The updated reference ... model resulted in a slightly lower estimate of initial biomass than the 2006 base case. The inclusion of ...
