1. Semi-empirical acoustic estimates of krill biomass derived from simulated commercial fishery data based on single-frequency acoustics

   Abstract:  Single frequency (38 and 120 kHz) acoustic and associated net data were extracted from US AMLR datasets and used to mimic data that might be collected by the commercial fishery during the fishing seasons. From these data we develop semi-empirical indices of acoustic biomass in a

2. Estimating Antarctic krill density from multi-beam observations using distance sampling methods

   Abstract:  The Scientific Committee has requested SG-ASAM to provide advice on the collection and processing of acoustic data from fishing vessels.  Some krill fishing vessels are equipped with scanning or multi-beam sonars.  Here I highlight a recently published analysis technique- an adaptation

3. Extending ecological monitoring to underpin the development of feedback management approaches for the Antarctic krill fishery

   Abstract:  CCAMLR has agreed to consider and develop a feedback management approach for the krill fishery. Such a management approach may also require the development of a new or extended monitoring programme for dependent species, especially if the krill fishery is to operate over large spatial

4. Plan of research program of the Russian Federation in Subarea 48.5 (Weddell Sea) in season 2012/13

   Abstract:  Closed mostly within the Weddell Sea Subarea 48.5 is one of the closed data-poor CCAMLR subareas, where stock assessment should be carried out. In spite of hard ice conditions during most of the time of the year, this large water area is very similar with the Ross Sea. This similarity,

8. Method of age determination for Antarctic toothfish (Dissostichus mawsoni)

   Abstract:  This work is based on material from Antarctic toothfish, collected in the Ross Sea from December 2004 to March 2005 on the longliner “Volna”.  Age was determined for 364 individuals. Currently widely applicable "the break and burn method" was used in the present work (Chilton,

9. Movement of Patagonian toothfish (Dissostichus eleginoides) in Subarea 48.3

   Abstract:  Movement of Patagonian toothfish in Subarea 48.3 was investigated using tagging program data.  Data from 33,322 tag releases and 4,203 tag recaptures were used. The mean movement rate of both sexes combined varied from 25 to 34 km year-1.  There was no significant difference in movement

10. Data requirements for research fishing

    Abstract:  There are currently two sets of requirements for reporting data from vessels conducting fishing for research purposes (i.e. research fishing): (1) research fishing conducted under Conservation Measure 24-01 (scientific research) requires that catch, effort and biological data be reported
