The conservation measure regarding (or stipulating) the interim distribution of trigger level in the fishery of Antarctic krill in Subareas 48.1 through 48.4 (CM 51-07) has continuously been renewed due the CCAMLR’s inability to establish an agreed, operational feedback management (FBM) approach. As the trigger level lacks any form of relationship with the actual stock condition this approach is strictly not in line with the CCAMLR ecosystem approach to management. FBM has been considered an alternative approach for decades, but still lacks a plan that can be made operational within realistic cost and effort levels.  Our proposal outlines that acoustic data would be collected, processed and reported continuously during the fishing season as measure of the available prey field. This information can be integrated with finer-scale knowledge of top predator feeding strategies and updated through specific scientific studies at regular (multiyear) intervals. The foundations of the proposal are that acoustic monitoring of the prey field of nearby predator colonies feeds into a decision-making framework that is far less dependent on land-based effort. We consider it important to base decisions on simple, understandable and robust relationships which in turn creates trust by the stakeholders and will enable an efficient implementation of FBM. Initiating the model development and the krill fishing-predator study now will bring the SG-ASAM work and our proposed FBM framework development into a similar timeline. While the proposed framework provides a clear way forward it will take several years to implement fully due to the required development of methodology and time series data.

Este documento contribuye al proceso de planeamiento para la designación de un Área Marina Protegida en el Dominio 1, liderado por la Argentina y Chile. En particular, este documento ofrece un análisis de biodiversidad por zona para la propuesta preliminar de AMP en el  Dominio 1, presentado durante el último encuentro del Grupo de Trabajo de Seguimiento y Ordenación del Ecosistema (WG-EMM-17/23; WG-EMM 17/24; WG-EMM-17/25 Rev. 1). Los objetos de conservación ocupan diferentes extensiones y están distribuidos de manera  diferente en el Dominio 1; mientras algunos ocupan áreas muy pequeñas como las polinias, otros se extienden sobre áreas más grandes, como las ecoregiones bentónicas. En general, resulta dificultoso proteger todas las características espaciales, particularmente cuando su distribución es compleja. El modelo de AMP para el Dominio 1 se desarrolló en base a las Áreas Prioritarias para la Conservación (APC, SC-CAMLR-XXXVI/17) y tomando en consideración la pesquería de kril y el cambio climático (SC-CAMLR-XXXVI/18). El modelo de AMP alcanza los niveles de protección de más del 90% de los objetos de conservación, incluyendo la protección para todas las áreas consideradas importantes para aves, mamíferos y peces. La propuesta de AMP cumple con el nivel de protección acordado por la comunidad internacional para el Dominio 1. Reducciones sustantivas del modelo de AMP podrían comprometer, en cierta medida, la protección de objetivos de conservación establecidos por la Convención, para la designación de AMPs en la Antártida.

Este documento es una contribución al proceso de planificación para la designación de un Área Marina Protegida en el Dominio 1, liderado por la Argentina y Chile (SC-CAMLR-XXXVI/17 y SC-CAMLR-XXXVI/18). Particularmente, este informe resume los resultados y decisiones adoptadas en una serie de talleres internacionales específicamente desarrollados para contribuir al proceso de planificación del AMP en el Dominio 1, incluyendo el Primer Taller Internacional celebrado en el año 2012 en Valparaíso, Chile, (WG-EMM-12/69); el Taller Binacional (Chile-Argentina) celebrado en La Serena, Chile, en el año 2013, (WG-EMM-14/40); el Segundo Taller Internacional para la identificación de Áreas Marinas Protegidas (AMP) en el Dominio 1, de CCRVMA, celebrado en 2015 en Buenos Aires (WG-EMM-15/42); y el Taller Informal sobre AMP en Dominio 1, celebrado en 2016, en Boloña, Italia (WG-EMM-16/73).

Este informe ha sido compilado por sus autoras, basadas en las discusiones de expertos que tuvieron lugar durante los talleres referidos. La lista de participantes para estos talleres puede encontrarse en el Anexo 3. Una versión revisada, que incluya la lista completa de autores (i.e los participantes a los talleres) se ha propuesto para su presentación en CCAMLR Science (SC-CAMLR-XXXVI/16).

The CCAMLR Scientific Committee in 2016 reviewed three scientific background documents in support of the development of a CCAMLR MPA in the Weddell Sea. Germany was asked to carry out further work, in particular regarding the issues and questions raised at WG-EMM-16 and SC-CAMLR-XXXV.

Here, the authors intend to update the Working Group on Fish Stock Assessment on the current state of the work carried out during the 2016/2017 intersessional period. Chapter 1 of this working group paper informs on the new data retrieval process. Chapter 2 presents the updated analyses of relevant data layers, including an update on the Antarctic toothfish habitat model. Chapter 3 provides a sensitivity analysis of the level of protection for Antarctic toothfish and other demersal fish that explores a range of protection-level scenarios. In this context, we show how the cost layer works. Subsequently, a revised Marxan approach based on the updated data layer is shown. In Chapter 4 we outline the way we - at that stage - transferred the results of the scientific analyses into the WSMPA borders and management zones.

Oceanites, Inc. is a US-based, nonprofit, scientific, and educational organization under US law, which was founded in 1987. Its mission is to champion science-based conservation and increased awareness of climate change and its potential impacts through the lens of penguins and Antarctica.

This report summarizes activities of Oceanites since CCAMLR-XXXV and SC-CAMLR-XXXV, including:

• Results from the latest, 23^rd consecutive field season of the Antarctic Site Inventory;

• Update on the Mapping Application for Penguin Populations and Projected Dynamics (MAPPPD);

• State Of Antarctic Penguins 2017 Report and Penguin Conservation Efforts;

The 2-year programme of exploratory fishing provided for by SPRFMO CMM 4.14 has been successfully completed and new and important biological information has been collected on toothfish outside the CCAMLR convention area. The key findings are that only Antarctic toothfish, Dissostichus mawsoni, were caught, that these were mostly male (~85%), and that most fish were in spawning condition or spent. These surveys provide information on the life history of Antarctic toothfish that is consistent with the current hypothesis on Antarctic toothfish growth and movement, and have provided the some of the first empirical scientific observations of spawning Antarctic toothfish. Information collected during these first two voyages will be shared with CCAMLR and had been used in the stock assessment of Antarctic toothfish in the Ross Sea region. Over the coming months, New Zealand will screen video footage and analyse all data collected in more detail than the timing of the voyages has allowed so far. In addition, to maximise the value of future data collection for both organisations’ understanding of the distribution, dynamics and status of stocks of Antarctic toothfish, New Zealand will also assess the optimum quantity and nature of data required to enable the development of a spatially-explicit integrated stock assessment model of Antarctic toothfish in the region. It is anticipated that this model, targeted for completion in 2021, will include those components of the Antarctic toothfish stock residing in the SPRFMO Area as well as in the CCAMLR Area. At this stage, it is intended that a comprehensive proposal for the future of the exploratory fishery will be presented to SPRFMO Scientific Committee in 2018.

The Ross Sea region has been known as an ecologically important area in the Antarctic with an extraordinary rich biota. To conserve marine living resources and the ecosystem of the Ross Sea, CCAMLR designated the area as a Marine Protected Area (MPA) at the 35th annual meetings in 2016. Since 2015, the Korean government (Ministry of Oceans and Fisheries) has been preparing to launch a research and development project (R&D) to contribute to CCAMLR’s efforts to conserve the area, and approved the budget for the said project for 5 years (2017-2022). The goal of the project is to understand the impact of climate change on the structure and function of the ecosystem of the Ross Sea region MPA. To that end, investigations on the spatial distribution of krill, biodiversity, the structure of the food web and biomagnification will be undertaken. To provide monitoring data on breeding parameters of krill-dependent species to the CCAMLR Ecosystem Monitoring Program (CEMP), investigations on population dynamics, breeding success and foraging behavior of the Adélie penguin will be conducted at Cape Hallett. Polynya dynamics, sea ice concentration and primary production will be observed in order to analyze how environmental changes affect the ecosystem. We look forward to taking a lead role in these research activities using our research infrastructure, such as the icebreaker research vessel ‘ARAON’, the air-network based on Jang Bogo Station, and the field camp at Cape Hallett.
