1. Length-weight relationships of six fish species associated with krill fishery in the Atlantic sector of the Southern Ocean

   Abstract:  Length-weight relationships (LWRs) of six fish species in the Southern Ocean, which commonly associated with Antarctic krill fishery, were determined. Samples were collected with Chinese krill trawler (codend mesh size 2 cm) in the Atlantic sector of the Southern Ocean from January to

2. Otolith elemental signatures reveal habitat shift of Electrona carlsbergi

   Abstract:  Electron subantarctic (Electrona carlsbergi) is one of important pelagic myctophidae which circumpolar distributed between the warm waters of the subtropical confluence zone and the Southern Ocean. The distribution, life history and migration pattern of this species were examined using

3. Analysis of the toothfish fishery indices in Subareas 88.1 and 88.2 when using different types of longline gears

   Abstract:  The indices of exploratory toothfish fishery in the Subareas 881 and 88.2 for the period of 2010-2016 are considered. Taking into account the different number of hooks at longlines sets used at the fishery, the catch indices were normalized to 1000 hooks.  The effect of the gear types

4. Stock assessment of mackerel icefish (Champsocephalus gunnari) in the vicinity of Kerguelen Islands (Division 58.5.1) after the 2017 Poker Biomass survey

   Abstract:  In 2017, a bottom trawl survey (PoKer 4) was undertaken at Kerguelen Islands (Division 58.5.1) to collect information about the size distribution and the biomass status of mackerel icefish, Champsocephalus gunnari. Data from this random stratified trawl survey was used for a short term

5. Changing status of three notothenioid fish at the South Shetland Islands (1983–2016) after impacts of the 1970–80s commercial fishery

   Abstract:  Owing to commercial fishing during the late 1970s/early 1980s, targeted notothenioid species had become depleted around the South Shetland Islands. Herein we report subsequent changes in the prevalence of three species, Notothenia rossii, Gobionotothen gibberifrons and N otothenia

6. Proposed process for independent review of CCAMLR toothfish stock assessments

   Abstract:  Following discussion at the Scientific Committee in 2016, we propose a process for independent review of CCAMLR integrated toothfish stock assessments based on the process used by the Center for Independent Experts (CIE, NOAA), and the benchmarking process used by ICES. Author(s):

7. Estimating nest-level phenology and reproductive success of colonial seabirds using time-lapse cameras

   Abstract:  We wish to draw the attention of Members to an online application of the R code published in the attached paper. The web-based app ‘photoR’ (https://jefferson.shinyapps.io/photor2) implements  the methods of the paper and provides summary outputs for direct input to CEMP A6b and A9

8. Impacts of rising sea temperature on krill increase risks for predators in the Scotia Sea

   Abstract:  Climate change is a threat to marine ecosystems and the services they provide, and reducing fishing pressure is one option for mitigating the overall consequences for marine biota. We used a minimally realistic ecosystem model to examine how projected effects of ocean warming on the

10. The winter pack-ice zone provides a sheltered but food-poor habitat for larval Antarctic krill

    Abstract:  A dominant Antarctic ecological paradigm suggests that winter sea ice is generally the main feeding ground for krill larvae. Observations from our winter cruise to the southwest Atlantic sector of the Southern Ocean contradict this view and present the first evidence that the pack-ice
