1. Exploration of CPUE standardisation variances in the Ross Sea (Subareas 88.1 and 88.2A South of 70°s) Antarctic toothfish (Dissostichus mawsoni) exploratory longline fishery

   Abstract:  Catch rates or catch per unit of effort (CPUE) are used for data-poor exploratory fisheries without integrated assessments in the CPUE by seabed area method to estimate stock biomass in the interim of collecting sufficient tag recaptures. Here, we address the two questions: (1) which

2. Proposed continuation of a multi-Member longline survey on Antarctic toothfish (Dissostichus mawsoni) in Statistical Subarea 48.6 in 2019/20 by Japan, South Africa and Spain

   Abstract:  A collaborative research program has been undertaken by Japan and South Africa since 2013 to enhance data collection and analysis in the subarea 48.6. From the last season (2018/19) Spain has joined the proposal in order to contribute to the data acquisition and to speed up the

3. The factors causing impact on the toothfish catch estimation on board of fishing vessels

   Abstract:  The toothfish catch estimation on board of fishing vessels at the CCAMLR area is being done often in a difficult weather conditions at sea, which can cause a negative impact on the measurement equipment. Besides, until today the “green weight” of the toothfish catch on fishing vessels

4. Analysis of the sea-ice concentration (SIC) in Subarea 48.6, research blocks 2, 3, 4 and 5 with sea-surface temperature (SST) and statistical models

   Abstract:  An Analysis of the sea ice concentration (SIC) in research blocks 2,3,4, and 5 of subarea 48.6, with sea surface temperature(SST) and statistical models is presented.  For research block 4, the SIC in 2019 was the highest for the last 4 years (2016-2019). For research block 5, the SIC in

5. Oceanographic study of the Subarea 48.6 with sea-surface temperature (SST) anomaly and vertical profile of sea temperature (PST)

   Abstract:  The Oceanographic study of the Subarea 48.6 on the SST, SIC, PST, current and wind vector was conducted. The lower SST corresponded to the higher SIC and vice versa. The PST  indicates  the  mixed  layer  depths  in  research  block5.  The  currents  around the research block 4 and 5

7. Continuation of the research program on study of life cycle, species compositions, biology and resource potential of craboids (Anomura, Decapoda) in the Pacific Ocean Antarctic Area from 2019/20 to 2020/21 by Russian Federation

   Abstract:  Russian program provides proposals to continue investigations of the species composition, biology, life cycle, distribution and structure of craboids stock (Anomura, Decapoda) and assess their resource potential in the Bellingshausen Sea (Subarea 88.3) and Amundsen Sea (Subarea 88.2).

8. Research program on Dissostichus spp. in Divisions 58.4.1 and 58.4.2 from 2019/20 to 2021/22

   Abstract:  The Scientific Committee considered the assessment of Dissostichus spp. in data-poor fisheries to be of a high priority (SC-CAMLR-XXIX, paragraphs 3.125 to 3.145). The use of different gear types for the implementation of a multi-Member research on   Dissostichus spp.  in East Antarctica

10. Modelling egg and larval transport of Antarctic Toothfish (Dissostichus mawsoni) in the East Antarctic region: Plan

    Abstract:  Antarctic Toothfish (Dissostichus mawsoni) is one of the target species that CCAMLR sets catch limits in the Southern Ocean. Due to their broad distribution relating to their life cycle and difficulties of in situ observations, life cycle with their spatial and temporal distribution is
