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 ... , one with the time series of krill abundance fixed on input, and the other incorporating an explicit ... model of krill dynamics. Additional versions of SMOM that may need to be conditioned are discussed. In ... suggest that penguins respond sooner than other predators to decreasing levels of krill abundance. Given ...
