    Abstract

    In 2010, POKER Biomass survey was undertaken at Kerguelen Islands (Division 58.5.1) to collect information of all the fish species including the mackerel icefish, Champsocephalus gunnari. Data from this random stratified trawl survey, added to the previous results of 2006, was used for a short term assessment of C. gunnari on Kerguelen EEZ. The standard CCAMLR methods were used to provide potential yields for the 2010/2011 and 2011/2012 seasons even if fishery doesn’t occur presently. A catch limit tonnes was simulated till the 2011/2012 season.
