We draw on this experience to illustrate the possible effect on CPUE in the TSRL fishery following reduction in resource access of a comparable magnitude, and assuming no other management change such as reduction in TAC or buy-out of commercial quota. In our scenario we therefore restrict the management change to the implementation of MPAs alone and apply the observed drop in catch rate that occurred in the adjacent Victorian fishery following introduction of MPAs. However, we note that MPAs are often implemented in association with other management changes and that outcomes are strongly influenced by these changes (Yamazaki et al., 2012).
