Exploratory fishery for Dissostichus mawsoni in Subarea 48.6
Owned byCommission for the Conservation of Antarctic Marine Living Resources (CCAMLR) – more>>
Fishery life cycleThis fishery started in 1997.

Overview: This fishery began as a new fishery in 1997 (Conservation Measure 114/XV). Following the Commission’s decision that high levels of illegal, unreported and unregulated (IUU) fishing for Dissostichus spp. in the Convention Area had rendered it unrealistic to consider this fishery as ‘new’ (CCAMLR-XVIII, paragraph 10.14), the fishery was reclassified as exploratory in 2000. Prior to 2017, this fishery was an exploratory fishery for Dissostichus spp., however, in order to better align the target species with the predominant species in this subarea the target species was specified as D. mawsoni, with any Patagonian toothfish (D. eleginoides) caught counting towards the catch limit for D. mawsoni.

  • Aquatic species-related measures
    The current limits on the exploratory fishery for D. mawsoni in Subarea 48.6 are described in Conservation Measure 41-04. From 2008 to 2013, the precautionary catch limit for Dissostichus spp. was set at 400 tonnes; 200 tonnes north of 60◦S (Small-Scale Research Units (SSRUs) A and G) and 200 tonnes south of 60◦S (SSRUs B-F). In 2014, the catch limit was revised to 538 tonnes and applied to a suite of research blocks (see Fig. 1). The target species was revised to D. mawsoni in 2017.
  • Fishing activity-related measures
    For the purpose of the exploratory longline fishery for Dissostichus mawsoni in Statistical Subarea 48.6, the 2020/21 season is defined as the period from 1 December 2020 to 30 November 2021.
Status and Trends
Type of Fishery: Exploratory. In this fishery, the catch of D. mawsoni reached a maximum of 517 tonnes in 2018. In 2020, 4 tonnes of D. eleginoides and 333 tonnes of D. mawsoni were caught.
