CONDITIONING SMOM USING THE AGREED CALENDAR OF OBSERVED CHANGES IN PREDATOR AND KRILL ABUNDANCE: A FURTHER STEP IN THE DEVELOPMENT OF A MANAGEMENT PROCEDURE FOR KRILL FISHERIES IN AREA 48
Abstract: The updated version of the Spatial Multi-species Operating Model (SMOM) of krill ... -predator-fishery dynamics described in an accompanying paper is conditioned using the WG-SAM set of ... reference observations for Area 48 (the SAM calendar). Results are presented for two implementations of SMOM ... , one with the time series of krill abundance fixed on input, and the other incorporating an explicit ...
