1. Scientific requirements for an orderly development of the krill fishery

   Abstract:  At CCAMLR XXV Australia presented the results of the BROKE-West acoustic krill biomass survey. These were used by the Scientific Committee to recommend to the Commission a revised precautionary catch limit for krill in Statistical Division 58.4.2 of 1.49 million tonnes (up from 450 000

2. Ecological risk management and the fishery for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea, Antarctica

   Abstract:  Ecological risk management is increasingly being applied to marine fisheries worldwide as an aid to developing management strategies to avoid, mitigate, or manage adverse outcomes. Risk management encompasses four major steps: recognition of risk; assessment of risk; development of

3. Interim protocol for fish/fish larvae by-catch observation in krill fishery

   Abstract:  This interim protocol has been developed in cooperation with our UK and Japanese colleagues/operators/observer coordinators in response to these recent requests by the CCAMLR Scientific Committee (SC-CAMLR 2006). The purpose of developing this protocol is to standardize the larval fish

4. CCAMLR scientific observation: tasks, priorities and time budget

   Abstract:  The workload of the tasks required in the CCAMLR Observer manual is assessed. The total time needed for the minimum amount of daily routine tasks was well above the capacity that an observer to undertake. The manual must be structured as its entirety so that the observer, only by

5. Analysis of krill fishery behaviour in the southwest Atlantic: potential signals for moving fishing activities amongst SSMUs

   Abstract:  This paper outlines the difference in fishing patterns between regions (Subareas) and seasons by analyzing CPUE (catch per hour) patterns towards the end of their sets of operations before leaving a SSMU, as well as its timing of the day, diurnal pattern of CPUE and fishing depth.

6. Size selectivity of the RMT8 plankton net and a commercial trawl for Antarctic krill

   Abstract:  Net selection of the scientific RMT8 plankton net and a commercial sized pelagic trawl has been studied. Selection curves indicate that krill length classes smaller 20 mm are underrepresented in the RMT8. For the commercial trawl with a liner mesh size of 12mm the length classes smaller

7. Histopathology of Antarctic krill (Euphausia superba) bearing black spots

   Abstract:  In Antarctic krill, Euphausia superba, sampled by a Japanese scientific observer onboard a krill fishing vessel in the winter of 2003 and 2006 in the South Georgia region, the Antarctic Ocean, approximately 2-5% of sub-samples of 100 krill bore small black spots. The black spots were

8. CCAMLR 2000 revisited

   Abstract:  The total abundance of krill in the Scotia Sea was estimated from an international echosounder and net survey (CCAMLR 2000) to be 44.3 million metric tons (Mt; CV=11.4%), prompting the Antarctic Treaty's Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR)

9. 2007 krill biomass update of the South Shetland and Elephant Island regions of Area 48

   Abstract:  Antarctic krill biomass trends in the South Shetland Island region of Area 48 are presented. Updated time series using the Stochastic Distorted Wave Born Approximation, and a dynamic?Sv krill delineation model are used to derive krill biomass. This paper provides updated (through summer

10. A guide to identification of fishes caught along with the Antarctic krill

    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,
