An approach to feedback management (FBM) of the krill fishery based on routine acoustic data collection and intermittent land-based predator studies
level in the fishery of Antarctic krill in Subareas 48.1 through 48.4 (CM 51-07) has continuously been ... Abstract: The conservation measure regarding (or stipulating) the interim distribution of trigger ... . As the trigger level lacks any form of relationship with the actual stock condition this approach is ... strictly not in line with the CCAMLR ecosystem approach to management.
