Abstract

The stock of Antarctic toothfish (D. mawsoni) in CCAMLR subarea 48.4 was estimated from tagging returns to be 1,027 tonnes during the 2013/14 season. 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 2014/15 yield of 35 tonnes compared to the 2013/14 TAC of 24 tonnes.
