Résumé

A bootstrap procedure was applied to estimate the demersal biomass of mackerel icefish (Champsocephalus gunnari) in CCAMLR subarea 48.3 using data from the UK trawl survey conducted in January 2013. The CCAMLR harvest control rule was then applied to determine catch limits for the 2013/14 and 2014/15 fishing season. Application of the CCAMLR rule, which ensures 75% biomass escapement after a two year projection period, yielded total allowable catch limit advice of 4635 tonnes for 2013/14 and 2659 tonnes for 2014/15.
