Preliminary results of the experiments on the krill transport study in the South Orkney area (April 1992)
area. The krill biomass was estimated within the square at the start and the end of works. It amounted ... of krill density and oceanological stations were carried out along the square perimeter. Four dublicates ... of krill density were obtained by 15-miles intercepts of the perimeter, along with mean water flow ... and geostrophic currents. The balance of krill input and output for the square was calculated based ...

Subdivision of large CCAMLR Statistical Areas for the management of the krill fishery
for their relevance to the management of the krill fishery. A rationale for developing some new areas is developed ... based on data on krill distributions. The overall aim of the exercise was to reduce the large size ... of many of the existing statistical areas to the point where all areas where krill occur could be surveyed ... by a single vessel. Areas where krill appeared to be generally absent were separated from those areas where ...

A comparison between the estimated density of krill from an acoustic survey with that obtained by scientific nets on the same survey
Abstract: This work presents the initial comparative analysis of acoustic and net haul krill ... as part of a hydroacoustic biomass survey for Antarctic krill in CCAMLR Division 58.4.1. The acoustic ... krill density estimates were consistantly larger than the net estimates, otherwise no relationship ... between acoustic and net krill density estimates. This variation was reduced by subsampling the data set ...
