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 ... ), 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 ... the 2007 recaptures of 2006 tags released had the most substantive impact on the model estimates ...
