Using the EPOC modelling framework to assess management procedures for Antarctic krill in Statistical Area 48: evaluating spatial differences in productivity of Antarctic krill
Abstract: Spatially explicit simulation models of the Antarctic marine ecosystem are needed to ... evaluate management procedures for the Antarctic krill fishery. The key issues to be resolved in the ... development of a harvest strategy are whether (i) spatial differences in the productivity of krill give rise ... , particularly as the fishery expands to take the large-scale catch limit. A fourth issue is to determine whether ...
