meeting 1.1 The 2016 meeting of WG-EMM was held at the National Research Council (CNR), Bologna, Italy, from 4 to 15 July. The meeting was opened by the Convener, Dr S. Kawaguchi (Australia), who welcomed participants (Appendix A) including Dr J. Zuzunaga from Peru (Acceding State; see also SC CIRC 16/39). Dr Kawaguchi thanked CNR for hosting the meeting. The Working Group was warmly welcomed by Dr A.M. Fioretti (Institute of Geosciences and Earth Resources, CNR). 1.2 Dr Kawaguchi reviewed the current work of WG-EMM and recalled that in 2015 the Scientific Committee indicated that the development of feedback management (FBM) of the krill fishery and the evaluation of candidate decision rules could be advanced by holding a workshop in 2016, perhaps associated with WG-EMM (SC-CAMLR-XXXIV, paragraph 3.44). Dr Kawaguchi advised that it had not been possible to hold such a workshop during WG-EMM-16. The Working Group’s work remained focused on the krill-centric ecosystem and issues related to the development of FBM. Adoption of the agenda and organisation of the meeting 1.3 The Working Group discussed the provisional agenda and agreed to add an item on general issues for spatial management (Subitem 3.3). The agenda was adopted (Appendix B), and subgroups were formed to address detailed aspects of the agenda. A one-day symposium on the Ross Sea ecosystem was held during the meeting (Item 4). 1.4 Documents submitted to the meeting are listed in Appendix C. While the report has few references to the contributions of individuals and co-authors, the Working Group thanked all authors of papers for their valuable contributions to the work presented to the meeting. 1.5 In this report, paragraphs that provide advice to the Scientific Committee and its other working groups have been highlighted; these paragraphs are listed in Item 5. 1.6 The report was prepared by M. Belchier (UK), T. Brey (Germany), R. Cavanagh (UK), A. Constable (Australia), R. Currey (New Zealand), C. Darby (UK), K. Demianenko (Ukraine), S. Fielding (UK),

This study analysed four groundfish biomass surveys (POKER 1–4) conducted from 2006 to 2017 across depths ranging from 100 to 1 000 m. Forty demersal species were recorded in total and density distributions of twenty presented. However, only seven species account for the majority of the biomass (96%). Total biomass was 250 000 tonnes during the first three surveys (POKER 1–3), and 400 000 tonnes for POKER 4 due to a high catch of marbled notothen (Notothenia rossii) and mackerel icefish (Champsocephalus gunnari) (accounting for 44% and 17% of the 400 000 tonnes biomass respectively).

    The spatial, temporal and structural distribution of Antarctic seafloor biodiversity by Jan Jansen, Dipl.-Biol. Under the supervision of Craig R. Johnson Nicole A. Hill Piers K. Dunstan and John McKinlay Submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Quantitative Antarctic Science Institute for Marine and Antarctic Studies (IMAS), University of Tasmania May 2019 In loving memory of my dad, whose passion for adventure, sport and all of nature’s life and diversity inspired so many kids, including me, whose positive and generous attitude touched so many people’s lives, and whose love for the ocean has carried over to me. The spatial, temporal and structural distribution of Antarctic seafloor biodiversity by Jan Jansen Abstract Biodiversity is nature’s most valuable resource. The Southern Ocean contains significant levels of marine biodiversity as a result of its isolated history and a combination of exceptional environmental conditions. However, little is known about the spatial and temporal distribution of biodiversity on the Antarctic continental shelf, hindering informed marine spatial planning, policy development underpinning regulation of human activity, and predicting the response of Antarctic marine ecosystems to environmental change. In this thesis, I provide detailed insight into the spatial and temporal distribution of Antarctic benthic macrofaunal and demersal fish biodiversity. Using data from the George V shelf region in East Antarctica, I address some of the main issues currently hindering understanding of the functioning of the Antarctic ecosystem and the distribution of biodiversity at the seafloor. The focus is on spatial biodiversity prediction with particular consideration given to previously unavailable environmental factors that are integral in determining where species are able to live, and the poor relationships often found between species distributions and other environmental factors.

Naganobu Affiliation(s) 1) Laboratory of Biology, Tokyo Kasei Gakuin University 2) National Research Institute of Far Seas Fisheries Published or accepted for publication elsewhere? Yes No x If published, give details ABSTRACT A field key to early life stages of Antarctic fish caught along with the Antarctic krill is produced. The key includes 8 families and 28 species mainly from the Atlantic sector of the Southern Ocean and uses distinguished characters which permit rapid field identification. In some cases, however, it is impossible to discriminate among species of the same family by remarkable characters. A species key is not shown for such resemble species and a brief summary of the main morphological features of species and genera is provided. SUMMARY OF FINDINGS AS RELATED TO NOMINATED AGENDA ITEMS Agenda Item Finding 4.3 We are producing a practical field key to juvenile fish caught along with the Antarctic Scientific krill. To our knowledge more than 40 species of fish have been found as by-catch. Observation However, the number of dominant fish species found in the krill catch never exceeds 20 species. An useful and practical identification key to these dominant species maybe facilitate the quantitative assessment of fish in the krill catch.

Pitman hey always remind me of witch’s hats—a little bit of THalloween in the winter wonderland. Looking across a flat plain of frozen Antarctic sea ice, I watch as a herd of killer whales swims along a lead—a long, narrow crack in the six- foot-thick ice. The fins of the males are black isosceles triangles, five feet tall, and they look like a band of trick- or-treaters coming our way. I am on board the U.S. Coast Guard icebreaker Polar Star as it back-and-rams the frozen ocean to open up a fourteen- mile-long channel into McMurdo Sta- tion, fifty feet at a whack.

  • A Balanced Model of the Food Web of the Ross Sea, Antarctica
    CCAMLR Science, Vol. 17 (2010): 1–31 A BALANCED MODEL OF THE FOOD WEB OF THE ROSS SEA, ANTARCTICA M.H. Pinkerton, J.M. Bradford-Grieve National Institute of Water and Atmospheric Research (NIWA) Ltd Private Bag 14901, Wellington 6241 New Zealand Email – [email protected] S.M. Hanchet NIWA Ltd PO Box 893, Nelson 7040 New Zealand Abstract A quantitative food web of the Ross Sea is presented here as a step towards investigating ecosystem effects of the fishery for Antarctic toothfishDissostichus ( mawsoni). The model consolidates quantitative information on trophic links across all the major biota of the Ross Sea and tests for data consistency. The model has 38 trophic groups and is balanced in terms of annual flows of organic carbon in an average recent year (1990–2000). The focus of the model is on the role of Antarctic toothfish in the food web which means that the model has greater taxonomic resolution towards the top of the food web than the base. A survey of the available literature and both published and unpublished data provided an initial set of parameters describing the annual average abundance, imports, exports, energetics (growth, reproduction, consumption) and trophic linkages (diets, key predators) for each model group. The relative level of uncertainty on these parameters was also estimated. This set of parameters was not self consistent, and a method is described to adjust the initial parameter set to give a balanced model, taking into account the estimates of parameter uncertainty and the large range of magnitude (>6 orders of magnitude) in trophic flows between groups.

Near,a,* James J. Pesavento,b and Chi-Hing C. Chengb a Center for Population Biology, One Shields Avenue, University of California, Davis, CA 95616, USA b Department of Animal Biology, 515 Morrill Hall, University of Illinois, Urbana, IL 61801, USA Received 10 July 2002; revised 4 November 2002 Abstract The Channichthyidae is a lineage of 16 species in the Notothenioidei, a clade of fishes that dominate Antarctic near-shore marine ecosystems with respect to both diversity and biomass. Among four published studies investigating channichthyid phylogeny, no two have produced the same tree topology, and no published study has investigated the degree of phylogenetic incongruence be- tween existing molecular and morphological datasets. In this investigation we present an analysis of channichthyid phylogeny using complete gene sequences from two mitochondrial genes (ND2 and 16S) sampled from all recognized species in the clade. In addition, we have scored all 58 unique morphological characters used in three previous analyses of channichthyid phylogenetic relationships. Data partitions were analyzed separately to assess the amount of phylogenetic resolution provided by each dataset, and phylogenetic incongruence among data partitions was investigated using incongruence length difference (ILD) tests. We utilized a parsimony- based version of the Shimodaira–Hasegawa test to determine if alternative tree topologies are significantly different from trees resulting from maximum parsimony analysis of the combined partition dataset. Our results demonstrate that the greatest phylo- genetic resolution is achieved when all molecular and morphological data partitions are combined into a single maximum parsimony analysis.
