Update report on marine mammal interactions in Division 58.4.4
Abstract: Fishing activities targeting Patagonian toothfish (Dissostichus eleginoides) occurs in Division 58.4.4 and killer whales have been observed to interact with the vessels until 2014. Interaction rates between areas and seasons vary greatly (from 0 to 70%). Depredation rates were updated

2019 Ross Sea shelf survey results and notification for research in 2020
Abstract: The time series of relative abundance and age structure from the Ross Sea shelf survey is an important input to the Ross Sea stock assessment. The annual survey has been conducted since 2012, with a revised proposal presented in 2017 for five years (2018–2022). The objectives of the

Statistical modelling of by-catch patterns: a preliminary case study using research fisheries in Subarea 48.6
Abstract: We report a preliminary result of statistical modeling of grenadier bycatch pattern by bottom longline research fisheries in CCAMLR Subarea 48.6, using generalized linear mixed models with zero-inflation. The result contains several issues including the failure of estimation in

Patagonian toothfish tagging study plan in the southwest Atlantic (FAO Area 41)
Abstract: We propose to conduct an exploratory satellite tagging campaign of Patagonian toothfish (Dissostichus eleginoides) in the Southwest Atlantic Ocean (FAO Area 41). Existing data on this species is extremely rare and incomplete in both study duration and geographic coverage. This proposal

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

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

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

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).

On acceptable scattering of longlines geo-referencing in the toothfish fishery in the CAMLR Convention Area
Abstract: The issues of longlines geo-referencing during the exploratory fisheries of the toothfish in the Convention Area are discussed. Cases of differences in the coordinates of settings and haulings are considered. The estimation of the maximum possible variation of the coordinates in the
