The 2013 assessment of abalone in Zones A-D is updated to take new data into account; these include results from the recent full population survey. Projections are shown for different scenarios for the future commercial and poaching catches in Zone A and Zone B. Current poaching levels (average of 2014 and 2015, estimated as 378t for Zone A, 293t for Zone B, 67t for Zone C and 139t for Zone D) if continued, would not be sustainable.
