1. 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

2. 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

3. 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

5. 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

6. The importance of sea ice association of Antarctic krill for transport and retention in the South Orkneys region: a modelling study

   Abstract:  The South Orkney Islands region is a key location for understanding the distribution of Antarctic krill in CCAMLR Area 48. The local krill populations support krill-dependent higher predators and krill fisheries, and the regional oceanographic circulation provides connections between the

7. Considerations about managing the krill fishery at small spatial and temporal scales

   the need for coupled research to ensure fishery displacement does not become too concentrated in other ...

8. Developing layers for a Risk Assessment for Subarea 48.1 using data from at-sea sightings

   Abstract:  CCAMLR has endorsed the use of the Risk Assessment framework to apportion the krill catch limits in order to minimise the risk of the fishery to krill dependent predators. We plan to apply the risk assessment framework across Subarea 48.1 at various spatial and temporal scales, in order

9. Developing a Risk Assessment for Subarea 48.1 using tracking data

   Abstract:  CCAMLR has endorsed the use of the Risk Assessment framework to apportion the krill catch limits in order to minimise the risk of the fishery to krill dependent predators. We plan to apply the risk assessment framework across Subarea 48.1 at various spatial and temporal scales, in order

10. The Mapping Application for Penguin Populations and Projected Dynamics (MAPPPD) database: a tool for helping stakeholders monitor penguin population trends in Antarctica

    Abstract:  The Mapping Application for Penguin Populations and Projected Dynamics (MAPPPD) is a web-based, open access, decision support tool designed to assist scientists, non-governmental organizations, and policymakers working to meet the management objectives as set forth by The Commission for
