1. A spatial multi-species operating model (SMOM) of krill–predator interactions in small-scale management units in the Scotia Sea

   Abstract:  A Spatial Multi-species Operating Model (SMOM) of the underlying krill-predator-fishery dynamics is developed in response to requests for scientific advice regarding the subdivision of the precautionary catch limit for krill among 15 small-scale management units (SSMUs) in the Scotia Sea

2. Time series of Drake Passage Oscillation Index (DPOI) from 1952 to 2006, Antarctica

   Abstract:  An assessment of the environmental processes influencing variability in the recruitment and density of Antarctic krill (Euphausia superba DANA) is important as variability in krill stocks affects the Antarctic marine ecosystem as a whole. Naganobu et al. (1999) had assessed variability

3. Progress towards a trophic model of the ecosystem of the Ross Sea, Antarctica, for investigating effects of the Antarctic toothfish fishery

   Abstract:  We report on the further development of a carbon-budget trophic-model of the Ross Sea with which to investigate effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The Ross Sea is a low primary production system, with production being localised in space and time. In

4. Further progress on modelling the krill–predator dynamics of the Antarctic ecosystem

   Abstract:  This paper addresses work conducted on the Mori-Butterworth multi-species model of the Antarctic ecosystem subsequent to the Ulsan meeting of the IWC Scientific Committee. Points raised about the model during that meeting are addressed in turn. Results are quoted that suggest that krill

5. A comparison of model predictions from KPFM1 and KPFM2

   Abstract:  We compare two versions of the krill-predator-fishery model to demonstrate the extent to which the predictions of KPFM1 can be reproduced with KPFM2. We also discuss the incorporation of seasonality into parameter estimates and a necessary change in the predator recruitment function of

6. Comparison of long-term trends in abundance, recruitment and reproductive success of five populations of Pygoscelis penguins in the South Shetland Islands, Antarctica

   Abstract:  Responses of predator populations to environmental variability in the Antarctic have tended to exhibit site- and species-specific differences owing to variation in geographic settings and predator life-history strategies. Five populations of Pygoscelis penguins from King George Island

7. KPFM2, be careful what you ask for – you just might get it

   Abstract:  We have substantially revised the krill-predator-fishery model that was presented to the WG-EMM in 2005. The new version of our model is called KPFM2, and we have addressed all four of the changes which the WG-EMM indicated would be required to use the model for providing advice on the

8. The krill maturity cycle: a conceptual description of the seasonal cycle in Antarctic krill

   Abstract:  A long term study on the maturity cycle of Antarctic krill was conducted in a research aquarium. Antarctic krill were either kept individually or in a batch for 8 months under different temperature and food conditions, and the succession of female maturity stages and intermoult periods

9. Learning about Antarctic krill from the fishery

   Abstract:  Antarctic krill has been studied for many decades, but we are still long way from understanding their biology to be able to make reliable predictions about the reaction of their populations to environmental change. This is partly due to certain difficulties in relation to logistics,

10. Intra-annual variability in the abundance of Antarctic krill (Euphausia superba) at South Georgia, 2002–2005: within-year variation provides a new framework for interpreting previous ‘annual’ krill density estimates

    Abstract:  Upward-looking acoustic Doppler current profilers (300 kHz, ADCP) and echosounders (125 kHz) were deployed on moorings on- and off-shelf to the northwest of South Georgia to measure abundance of Antarctic krill continuously between 14 October 2002 and 29 December 2005. A distinct
