Abstract
The General Linear Model (GLM) approach used last year needs to be updated for use in standardising the commercial abalone CPUE time series (1980 – 2006) of abalone for the influence of other factors on the CPUE apart from resource abundance. The raw data were supplied by A. Mackenzie and G. Maharaj (MCM). The number of new data entries added to the database is 483 (all from Zone B), bringing the total number of data entries to 41432. The comparability of the new data with the older data needs to be discussed. Note that the recent nominal CPUE for Zone B is the lowest yet.
