    Abstract

    The stock of Antarctic toothfish in the CCAMLR subarea 48.4 was estimated using as the Petersen method as  640 tonnes. Application of the harvest rate used for D. eleginoides in Subarea 48.3 (γ = 0.038) gives yields of 24 t for the Antarctic toothfish in the region vs. previous estimation of 30 tonnes.
