Abstract
The proposed new area-disaggregated OMP for the West Coast rock lobster operates on the basis of: • Combining resource indices for trap CPUE, hoopnet CPUE, FIMS and somatic growth for the various super-areas into single indices for the resource as a whole; • using these indices and past catches to fit a simple age-aggregated population model; • using the results from that population model fit, together with some of the resource index data and applying certain constraints, to provide an overall TAC; and • finally splitting that overall TAC between super-areas making use of information on the trends of resource indices in each.
