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 ...

On the examining of krill flux
Abstract: In connection with future calculation of volume of krill immigration/emigration (flux ... ) in the choosen polygones, the proves of active long-distance migrations of krill are considered. These proves ... , is the valuation of krill retention time. To make it more correct and natural it is necessary to take into account ... the biological characteristics of krill, especially for the regions outside the shelf and slope areas ...

Krill stock evaluation with data from commercial fishing vessels
Abstract: Commercial krill fishing vessels can provide useful data for science and management ... a time-frame of a week and linked to krill length data from the same period. The data from the fishing ... operations were very different from transect data collected just some days before. Krill concentrations were ... . The data have the potential of providing information about local krill depletion, fishing patterns and diel ...

Some characteristics of krill transport in the Scotia Sea based on the Russian survey data
Abstract: In this work the characteristics of krill transport across the SSMUs determined ... will be accompanied with krill biomass transport across the boundaries of the SSMUs. Our estimates of krill flux out ... . It is shown that total krill biomass of 3.392 mln.t. transported by water mass out three SSMUs is comparable ... to the total precautionary yield value in the Scotia Sea comprising 3.17 mln.t. It is concluded that krill ...

Krill distribution related to water structure and dynamics on the South Georgia shelf in January 2000 (AtlantNIRO-BAS Core Programme 1999/2000)
Abstract: Research on water structure and dynamics, krill biomass assessment, biology ... in each box. Krill were distributed rather evenly throughout both boxes, but no dense concentrations were ... apparent. In the western box krill density was nearly 0.2 glm3 and in the eastern box was 1.8- 4.7 glm3 ... • Juvenile krill of 30-36 mm length were observed in the shelf zone and larger specimens, including spawning ...
