Growth of mackerel icefish (Champsocephalus gunnari) and age-size composition of population in subarea of the South Georgia
Abstract: Age, growth rate and age composition of icefish catches in subareas 48.3, 48.2, 48.1 ... were studied for different periods. The analysis of age composition of icefish in subarea 48.3 showed ... represented by fish of two contiguous age groups. It was shown that in the 1980s during a number of years the ... catches were based on fish of two contiguous year classes, strong 1984 year class and middle 1983 year ...

Assessment models for Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 SSRUs 88.2C–G for the years 2002–03 to 2010–11
assessment model of Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 covering SSRUs 88.2C, D, E, F ... several sensitivities including (i) unaccounted mortality due to lost gear, (ii) catch and tag data from ... from lost gear had little impact on estimates of biomass. The inclusion of tag data from the south ... from all vessels led to a 20% increase in biomass. We believe that the SSRU 88.2C–G model provides a ...
