Subdivision of large CCAMLR Statistical Areas for the management of the krill fishery

In this paper the boundaries of the CCAMLR statistical areas are examined 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 krill appeared to be abundant. Areas where there were identified concentrations or “stocks” were kept intact wherever possible. The resultant map of suggested management areas results in a series of subdivisions of far more regular size than the existing map of Statistical Areas.
