Using the EPOC modelling framework to assess management procedures for Antarctic krill in Statistical Area 48: evaluating spatial differences in productivity of Antarctic krill
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 ... to differential affects on predators in different locations, (ii) movement of krill between locations ameliorate ... any local fluctuations in krill abundance and (iii) fishery behaviour could be constrained by regional ...
