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 ...

A quantified Bayesian maximum entropy estimate of Antarctic krill abundance across the Scotia Sea and in small-scale management units from the 2000 CCAMLR survey
Abstract: We present the results of an alternative method of estimating krill abundance, and ... producing maps of krill distribution, from the data collected during the 2000 CCAMLR survey of the Scotia ... Sea. Using a probabilistic Bayesian Maximum Entropy (MaxEnt) technique, density values for the ... unsurveyed off-transect portions of the survey area were found by interpolation, and thus values for total ...
