Krill catch distribution in relation to predator colonies 1987 to 1992

The distribution of krill catches in relation to land-based predator colonies, calculated from CCAMLR fine-scale data, is shown for Subareas 48.1 and 48.2. The pattern of catches in 1992 is similar to that seen for other years, with 70% of the total catch from Subarea 48.1 being taken within 100 km of colonies and between the months of December to March inclusive (the ‘critical period-distance’). Although data reporting was not complete for Subarea 48.2 in 1992, it was estimated that 38% of the total catch from this subarea was taken in the critical period distance, compared to 5 to 78% in previous years. It is estimated that the catch in the critical period-distance was equal to 12% and 15% of the total exploitation of krill in these two subareas respectively.
