Abstract
The existing standardized CPUE indices for trapboats and bakkies in Area 8 comprise data from Area 8 only and an ad hoc adjustment is made to accommodate the movement of lobster into the area East of Hangklip (Areas 12-14) by increasing the size of Area 8 over a period of time. Recently Glazer and Butterworth (2010) presented results from GLM analyses applied to data from Area 8+ (Areas 8, 10-14) for the two methods of fishing. Updated results are presented here and a method is applied whereby the indices of abundance derived from the Area 8 and Area 8+ analyses are combined to provide a composite index of abundance for trapboats and bakkies respectively.
