This paper presents an update of the standardisation of the abalone CPUE using a GLMM approach proposed by Brandão and Butterworth (2012), which adds new data for the 2013/2014 fishing “year” in Zones A and B. The standardised CPUE value for Zones B for the 2014 model-year is slightly lower than the corresponding value for 2013 while that for Zone A is slightly higher. Excluding the 2013 index for Zone A, the 2014 indices are the lowest on record for each of these Zones.
