Simulating single area management on two sardine components

This document considers alternative methods to simulate the spread of directed sardine catches between the west and south components of sardine in cases where a candidate Management Procedure allocates a single area TAC, but the Operating Model assumes two sardine components. The document is written to provide background information to the key question to the panel “What would be the best way to simulation test the impact of a single area directed sardine TAC in a situation of two spatially distinct sardine population components”?
