Allowing for time-varying selectivity in South Coast rock lobster assessments

The Reference Case (RC) age-structured production model that has been used for past South Coast rock lobster assessments (ASWS/JUL07/SCRL/ASS/1) has assumed a time-invariant age-specific selectivity function. Previous work allowing the possibility of deviations from this assumption has used a model identical to the RC model, except that the age-specific selectivity function is allowed to vary over the time period for which catch-at-age data are available (1994 to yrecent).
