SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Dissostichus mawsoni

SPECIES NAME(s)

Antarctic toothfish

Antarctic toothfish (Dissostichus mawsoni) has a circumpolar distribution. The biological stock structure is not yet defined, but the Ross Sea area is considered a unique population based on physical oceanography (oceanic gyres may retain eggs, larvae juveniles), and on the limited movement of adult tagged fish (Acoura Marine, 2015). Two assessment units are established in the Ross Sea: i) Ross Sea stock (RSR) and Amundsen Sea Region (ASR).

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

DATA NOTES
  1. Currently stock assessments and management areas in the Ross Sea subareas (88.1 and 88.2) do not coincide, i.e. “For fisheries management purposes, Subareas 88.1 and 88.2 are split into three areas. For stock assessment purposes all of Subarea 88.1 and SSRUs 88.2A and 88.2B are treated as a single ‘Ross Sea’ stock. SSRU 88.2E is treated as a separate stock, ‘SSRU 88.2E’” (Ministry of Fisheries, 2010).
  2. Fishing mortality and spawning biomass estimates in the scores datasheet only refer to the ‘Ross sea’ stock assessment; while catch and set TACs only refer to Ross sea Subarea 88.1.
  3. Catches data includes estimated IUU catch.
  4. As the Commission on the Conservation of Antarctic Marine Living Resources (CCAMLR) is responsible for both scientific advice and management of the stock, we are assuming that Advised TAC = set TAC (CCAMLR, 2010a).
