1. 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

2. 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

3. 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

4. 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,

5. 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

6. Integrated analyses of circumpolar climate interactions and ecosystem dynamics in the Southern Ocean (ICED)

   Abstract:  ICED is a multidisciplinary, international initiative recently launched in response to the increasing need to develop integrated circumpolar analyses of Southern Ocean ecosystems. The long-term goal of ICED is to develop a coordinated circumpolar approach to understand climate

7. On possible influence of continuous krill fishing technology with the use of ‘air-bubbling suspension system’ on ecosystem elements

   Abstract:  It was shown that potential increase in krill fishery in the immediate future, accompanied by introduction of highly intensive fishing and processing technologies call for studying the fishery influence on ecosystem components beyond the framework of traditional investigations of

8. An illustrative management procedure for exploring dynamic feedback in krill catch limit allocations among small-scale management units

   Abstract:  A Management Procedure (MP) approach is proposed to assist in advising regarding the subdivision of the precautionary catch limit for krill among 15 small-scale management units (SSMUs) in the Scotia Sea to reduce the potential impact of fishing on land-breeding predators. The Spatial

9. Managing ecosystem uncertainty: critical habitat and dietary overlap of top-predators in the Ross Sea

   Abstract:  We summarize three types of data in order to increase appreciation among fishery managers of the close spatial and temporal ecological overlaps among top predators in the Ross Sea Shelf Ecosystem (RSShE). This includes data on diet, foraging behavior, and habitat use. Murphy (1995)

10. A compilation of parameters for a krill–fishery–predator model of the Scotia Sea and Antarctic Peninsula

    Abstract:  We describe the compilation and derivation of parameters for use in krill-fishery-predator models of the Scotia Sea – Antarctic Peninsula region. The primary aim is to provide input for the model developed by Watters et al. (2006), which we use to define the required parameters. However,
