1. Seamount-specific biomass estimates from SSRU 88.2H in the Amundsen Sea derived from mark-recapture data

   Abstract:  Mark-recapture data for Antarctic toothfish from individual seamount features in SSRU 88.2H were analysed to estimate biomass trends on isolated seamounts. Biomass estimates were also calculated for SSRU 88.2H as a whole. The analyses indicate that: Fish seldom move among seamounts

2. Preliminary investigations into a two-area stock assessment model for Antarctic toothfish (Dissostichus mawsoni) in the Amundsen Sea Region

   Abstract:  In 2013, the Scientific Committee of CCAMLR could not achieve consensus on a stock status for Antarctic toothfish in the Amundsen Sea Region (ASR- Subarea 88.2 SSRUs 88.2C-H) and identified several areas for further work. This work was carried out and presented to WG-SAM in 2014, who

3. Results of the third CCAMLR sponsored research survey to monitor abundance of subadult Antarctic toothfish in the southern Ross Sea, February 2014 and development of the time series

   Abstract:  At its 2011 meeting, the Scientific Committee agreed that a time series of relative abundance from a well-designed survey could be a useful input into the Ross Sea stock assessment model. The first survey was completed in February 2012, and the second survey in February 2013. In this

4. Investigating emigration in stock assessment models of Antarctic toothfish (Dissostichus mawsoni) in Subarea 88.2 SSRUs 88.2C–H

   Abstract:  In 2013, the Scientific Committee of CCAMLR could not achieve consensus on a stock status for Antarctic toothfish in Subarea 88.2 SSRUs 88.2C-H and identified several areas for further work. This was presented to WG-SAM in 2014, and found that the models were unable to fit patterns in

5. Has krill fishing the potential to adversely affect recruitment in Antarctic notothenioid fishes?

   Abstract:  A few years after krill (Euphausia superba) fishing had started in 1972/73, it became known that early life stages of Antarctic fish are associated with krill aggregations and are subject to by-catch in fisheries targeting krill. The species composition of fish by-catch in krill

6. Modelling the circumpolar distribution of Antarctic toothfish using correlative species distribution modelling methods

   Abstract:  This paper presents correlative species distribution modelling methods that could be used to predict the circumpolar distribution of habitat suitability for Antarctic toothfish. Potential environmental covariates that could be included in these models are presented for discussion and

8. Large-scale oceanographic fluctuations drive Antarctic petrel survival and reproduction

   Abstract:  Polar Regions are experiencing environmental changes at unprecedented rates. ese changes can spread throughout entire food webs from lower trophic levels to apex predators. As many top predators forage over large areas, these indirect e ects may be associated with large-scale patterns of

10. Coastal weather drives foraging behaviour of chinstrap penguins, Pygoscelis antarctica

    Abstract:  There is increasing interest in using higher-trophic level predators as ecosystem indicators because their performance is presumed to be linked to the overall function of the ecosystem that supports them. In the southwest Atlantic sector of the Southern Ocean, Antarctic krill (Euphausia
