WG-FSA-14 - 4.1.3 - Dissostichus eleginoides and D. mawsoni Subarea 48.4

Résumé

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.
