Abstract
Data from the FIMS surveys carried over the period 1992/93 to 2008/09 have been re-analysed here. This re-analysis 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. The methodology for calculating abundance indices has also been changed slightly.
