The 2004 analysis providing a catchability ratio for the Africana with the
new compared to the old gear is refined and extended given additional
data. The results of 1.18 (SE 0.10) for this ratio for M. paradoxus and 0.72
(SE 0.05) for M. capensis are both somewhat higher than obtained
previously, primarily as a result of the additional data now available. An
attempt is made at estimating the length dependence of these calibration
factors, but the data are found to have insufficient information content to
justify this.
