Abstract

Further work in the development of OMP-13 has continued with modifications to the documentation and code, mostly to allow for a generalisation towards one or two sardine stocks and one or two directed sardine TACs (de Moor and Butterworth 2013a). This document provides updated results for no catch scenarios and candidate MPs assuming a single sardine stock hypothesis, with different levels of variability about the stock recruitment relationship. Initial results are also presented for a no catch scenario and candidate MPs assuming a two sardine stock hypothesis; risk under this two stock hypothesis is discussed. Results are presented for candidate MPs which set a single sardine TAC only. The split of the sardine catch between the “west” and “south” stocks, in the case of the two sardine stock hypothesis, is based on a relationship with the ratio of the directed sardine TAC to the “west” stock 1+ biomass in the previous November (de Moor and Butterworth 2013a).
