    An updated and revised assessment of the Patagonian toothfish (Dissostichus eleginoides) stocks in Kerguelen and Crozet areas is presented. This study is based on a CASAL (C++ Algorithmic Stock Assessment Laboratory) model. Different statistical and biological datasets are used: catches, tag releases/recaptures data, commercial catch-at-length data and data from the recent POKER survey (2013). Preliminary results show stable estimates of biomass and SSB never fall below 60% of the initial biomass considering the actual level of catches (5100t in Kerguelen and 700t in Crozet).
