    Résumé

    Estimates of absolute numbers of recruits to the stock of patagonian toothfish around the Heard Island region are calculated from density at length data derived from stratified trawl surveys. The estimates are referred to the four year-old age class. The parameters for a lognormal recruitment distribution suitable for use in a population model are calculated.
