dc.description.abstractThis paper describes the simulation testing of three alternative decision rules (DRs) for setting catch limits for abalone in Zone F. Although there is very little change in the values of many of the performance statistics across all three DRs, it is clear from the results that continued poaching dominates future resource trends. However decision rule DR1 (which is similar to the existing decision rule) hardly responds to the overall downward trend in resource abundance, keeping the median legal TAC virtually unchanged. Hence it is suggested that a change to the existing decision rules be considered.en_ZA
