    Resumen

    The stock of Antarctic toothfish in the CCAMLR subarea 48.4 was conservatively estimated using the Chapman method as 621 tonnes. At a harvest rate of γ = 0.038 this would indicate a 2015/16 yield of 24 t for the Antarctic toothfish in the region, compared to the previous 2014/15 estimation of 28 tonnes.
