1. Introducing Casal2 for toothfish stock assessments

   Abstract:  The Casal2 software implements an updated generalised age-structured marine population model that allows more flexibility in specifying the population dynamics, parameter estimation, and model outputs than CASAL. Models are built with user-defined categories such as area, sex and

2. Casal2: New Zealand’s integrated population modelling tool

   Abstract:  Casal2 (pronounced Casal-two) has replaced CASAL, New Zealand’s integrated fish stock assessment pack-age since 2002. Casal2 replicates most of CASAL’s functions such as many stocks, fisheries, and areas; age-or length-based dynamics; the use of several data sources (e.g., abundance

3. Informing and seeking advice from WG-SAM-18 about the revisions of the WSMPA proposal

   Abstract:  Following the submission of a first draft Conservation Measure for establishing a MPA in the Weddell Sea (WSMPA) to CCAMLR 2016, Germany has carried out further work on the WSMPA proposal with a view for a revised CM proposal to be submitted by the EU to CCAMLR 2018. This document

4. Improving mechanistic understanding between larval krill, krill recruitment, and sea ice

   Abstract:  Antarctic Krill, Euphausia superba, is the key species of the Southern Ocean ecosystem. Earlier analysis suggested decrease in krill abundance by 50% since the mid 1970’s to early 2000’s in the Southwest Atlantic Sector, which has been specifically linked to a decrease in extent and

5. Outline for year 3 of the 3-year longline survey to determine toothfish population connectivity between Subareas 48.2 and 48.4

   Abstract:  This paper outlines the specific research objectives and plan to achieve them for the third year of an agreed 3-year longline survey, in the wider context of connecting the recently undertaken surveys in Subarea 48.2 with the established fishery in Subarea 48.4. The overall research

6. Diet overlap among top predators at the South Orkney Islands, Antarctica

   Abstract:  In order to understand interspecific trophic relationships among top predators, we analyzed diet information on nine bird and two seal species collected in the austral summer from 1996 to 2000 at South Orkney Islands. Overall, the diet of most of the predators was mainly composed of

7. Foraging patterns in the Antarctic Shag Phalacrocorax bransfieldensis at Harmony Point, Antarctica

   Abstract:  During the 1995 and 1996 summer seasons the foraging patterns of the Antarctic Shag Phalacrocorax bransfieldensis were studied by direct observation on individuals breeding at Harmony Point, Nelson Island, South Shetland Islands. During pre-laying and incubation individuals of both sexes

8. Candidate baseline data for ecosystem indicators in the Ross Sea region

   Abstract:  The research and management plan for the Ross Sea region MPA is currently under development. That plan will identify key research questions that aid in assessing the MPA’s efficacy in achieving its objectives. It may be helpful to have an agreed set of baseline data for key species which

9. Summary of New Zealand research projects relevant to the Ross Sea region Marine Protected Area

   Abstract:  This paper provides a summary of research projects and activities led by New Zealand researchers that are relevant to spatial planning, monitoring and research in relation to the Ross Sea region Marine Protected Area. The inventory includes: (1) research to establish “baseline”

10. Research concept on catchability to study toothfish abundance/stocks in the Antarctic marine areas

    Abstract:  Main two methods, which are used for the estimation of abundance/stocks of toothfish in the Antarctic marine areas, are the method based on tag recaptures and the method grounding on the CPUE data. But calculation of toothfish abundance with using these methods demands a number of
