A method to separate the South Coast rock lobster annual catches by Area for the areadisaggregated assessments was described in WG/04/08/SCRL08. Concern was raised about an assumption made with respect to the calculation of those catches, namely that the spatial distribution for HBF was the same as for other companies over the period in which HBF under-reported catches (19971 -2000). The calculations presented in this paper offer an alternative method of separating the annual catches, taking the concern raised above into account.
