Abstract
The possible effects of the introduction of MPAs on hake CPUE, and hence on the performance of the hake OMP, is examined for a number of scenarios. The impact is modeled as a change in catchability q whose existence and magnitude is unknown to the manager. Retuning the OMP to adjust for this could necessitate lowering annual TACs for the next five years by some 15-20 thousand tons to maintain the same levels of risk for the M. paradoxus population. Naturally this magnitude depends on the size of the change in q assumed (here some 20%).
