dc.description.abstract de Moor and Butterworth (2012a) presented results for a “Base MP” variant which contained mostly the same constraint parameters as OMP-08, except for a lower maximum total anchovy TAC. That “Base MP” variant was tuned to risk levels ( < 21.0 S risk and < 18.0 A risk ) which corresponded to a similar extent of leftward shift of the biomass distribution from a no catch to a catch scenario as that simulated under OMP-08. However, when used to determine the acceptable level of risk for anchovy, this approach resulted in a counter-intuitive result of lesser acceptable levels of catch from a resource now estimated to be more productive than was previously the case. This document further explores a method to determine an acceptable level of risk for anchovy and provides comparative results for different trade-off curves for the same “Base MP” tuned to different levels of anchovy risk, as well as for a few key alternative MP variants. The Harvest Control Rules are described in de Moor and Butterworth (2012b) and the simulation testing framework used for all alternatives is described in de Moor and Butterworth (2012c). en_ZA
