A possible framework in which to consider plausible models of the Antarctic marine ecosystem for evaluating krill management procedures
Abstract: CCAMLR requires an assessment method for recommending a subdivision of the krill catch ... limit in Area 48 that will be highly likely to achieve the objectives of the convention despite the ... uncertainties in knowledge. This will be part of the management procedure governing the krill fishery. The ... agreed workplan for developing a management procedure includes the evaluation of candidate management ...
