A proposal for large scale sampling of krill in the diet of predators across Area 48 to coincide with the CCAMLR synoptic survey
of Antarctic krill Euphausia superba across the Scotia Sea. Resolution of the spatial component ... of this variability requires a 'snapshot' of the krill population over the region (eg the CCAMLR B0 survey ... . At South Georgia krill in the diet of Antarctic fur seal Arctocephalus gazella show a good level ... of concordance with scientific net samples. In order to examine the potential of using krill in the diet ...

Krill fishery report: 2006 update
Abstract: This report on the krill fishery in Area 48 has been prepared in a format similar ... 5 Contracting Parties are fishing for krill in Area 48 in the 2005/06 season, and these vessels have taken 64415 ... t of krill to date. Two CCAMLR scientific observers have been deployed. The preliminary estimate of the total ... catch of krill for the season is approximately 97090 t. This compares with 127035 t of krill reported ...

Assessment of fishable krill biomass on the basis of the acoustic surveys results using geostatistical methods
of krill density based on the acoustic survey data is demonstrated. The results obtained indicate ... usefulness of these methods in studying the structure of krill density field for biomass assessment ... in compliance with different thresholds of their fishery importance. The structure of krill density field ... in Subarea 48.3 based on the surveys 2000 and 2002 indicates that krill fishable biomass is concentrated ...
