Development of a fine-scale model of land-based predator foraging demands in the Antarctic

The CCAMLR Secretariat has been requested to provide annual calculations of the catch of krill within the critical period-distance of land-based predators in Subareas 48.1 and 48.2 (100km from colonies, December - March). This index of the overlap of predators and the fishery is unsuitable for a number of reasons. An alternative method of calculating an index of fishery-predator interaction is developed, which is based on a detailed model of the supposed functional interaction between these two utilisers of the krill resource.
