Progress towards an assessment of Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 SSRUs 882C–H for the years 2002–03 to 2015–16 using a two-area model S. Mormede, K. Large and S. Hanchet
Resumen:
This paper presents further progress towards a two-area stock assessment model for Antarctic toothfish (Dissostichus mawsoni) in the Amundsen Sea region, defined here as SSRUs 88.2C–H. The region is split into two main areas: the North (SSRU 88.2H) comprising large mature fish, and the South (SSRUs 88.2C–G) comprising a mix of large mature fish and small immature fish.

Resumen:
The WG-SAM in 2016 “agreed the importance of identifying a set of diagnostics and clear criteria to assess the likelihood that a vessel is operating as would be expected in normal research activities”, further noting that a characterisation of fishing activities was also required in order to achieve such a goal (WG-SAM 2016, paragraph 4.19).

Resumen:
The third year research plan of Ukraine in subarea 48.2 by the fishing vessel SIMEIZ is provided. The survey design remains the same as in the second (2016) year. Ukraine proposes to divide the stock (the catch limit) in the researched area on two blocks – Northern and Southern, in order to reach maximum coverage of the subarea by the research stations.
