An approach to feedback management (FBM) of the krill fishery based on routine acoustic data collection and intermittent land-based predator studies
Abstract: The conservation measure regarding (or stipulating) the interim distribution of trigger ... level in the fishery of Antarctic krill in Subareas 48.1 through 48.4 (CM 51-07) has continuously been ... . As the trigger level lacks any form of relationship with the actual stock condition this approach is ... reported continuously during the fishing season as measure of the available prey field. This information ...
