Abstract
Data from the FIMS surveys carried over the period 1993 to 2009 have been re-analysed here. This reanalysis was necessary because verification of the data resulted in several corrections. These corrections mainly involved differentiation of records that had a zero catch associated with them when in fact the trap had been lost or open or not set. The total area of each Zone as well as the area for each transect surveyed was also re-calculated (see van Zyl et al., 2009). The allocation of stations to hotspot areas changed in some cases from that in previous analyses. Changes in methodology in calculating abundance indices has also been changed slightly. It should be noted that the results presented here are still preliminary.
