The management procedure used to recommend total allowable catches (TACs) and bycatches (TABs) for sardine and anchovy in South African waters is currently being revised. Given the extensive testing desired for this new management procedure, which among other factors includes taking account of the possibility of multiple sardine stocks and of the impact of the recommended catches on penguins, a final version of OMP- 13 is not yet available. However, the Small Pelagic Scientific Working Group has agreed a revised version of “Interim OMP-13”, called “Interim OMP-13v2” for use in June 2013 for calculating recommended final TAC/Bs for 2013. The revised management procedure, OMP-13, is expected to be finalised and agreed during 2013. This document details “Interim OMP-13v2”.
