    Abstract

    The stock of Antarctic toothfish (D. mawsoni) in CCAMLR subarea 48.4 was conservatively estimated from tagging returns to be 1068.7 tonnes. In previous years the harvest rate used for Patagonian toothfish (D. Eleginoides) in Subarea 48.3 (γ = 0.038) has been used as a precautionary harvest rate which would imply a 2016/17 yield of 40.6 tonnes compared to the 2015/16 TAC of 39 tonnes.
