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. Updated biological parameters of Dissostichus mawsoni at Subarea 48.6

   Abstract:  To achieve the milestone “Updating biological parameters for the population, suitable for inclusion in CASAL: Age Length Key (ALK), growth curves, maturity ogives” (SC-CAMLR-37 Report, para 3.130), this paper represents the updated length-weight relationship, growth curve, ALK, and

3. 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

5. A preliminary proposal to conduct a local survey of the Champsocephalus gunnari by the midwater trawl in the Statistical Subarea 48.2

   Abstract:  Mackerel icefish (Champsocephalus gunnari) – one of the most common and widespread species of Antarctic fish. Ukraine proposes survey of Champsocephalus gunnari at previously scheduled stations (trawlings) points in the statistical Subarea 48.2. The main objective of the research is to

6. Revised CASAL model for D. eleginoides with updated biological parameters at Division 58.4.4b

   Abstract:  In order to achieve the milestone “1.1 Update biological parameters”(SC-CAMLR-37 Report, Annex12), biological parameters (length-weight relationship, growth curve, Age Length Key, and maturity ogice) of Dissostichus eleginoides for Division 58.4.4b were updated based on the data gathered

7. Updates to Fishery Reports – A prototype based on the ‘Exploratory fishery for Dissostichus mawsoni in Subarea 48.6’ Fishery Report

   Abstract:  This document presents a prototype of Fishery Report built using R Markdown. Documents produced in R Markdown may be exported into pdf format (this paper) as well as html pages (available on the SAM meeting server). The 2018 Working Group on Fish Stock Assessment welcomed the Secretariat

8. Habitat partitioning in Antarctic krill: spawning hotspots and nursery areas

   Abstract:  Antarctic krill, Euphausia superba, have a circumpolar distribution but are concentrated within the south-west Atlantic sector, where they support a unique food web and a commercial fishery. Within this sector, our first goal was to produce quantitative distribution maps of all six

10. Krill (Euphausia superba) distribution contracts southward during rapid regional warming

    Abstract:  High-latitude ecosystems are among the fastest warming on the planet. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting. Here, we show that, within their main population centre in the southwest Atlantic sector, the distribution of
