Demographic studies for CEMP

This paper responds to a request (WG-EMM-02 paragraphs 3.46 to 3.47) for standard methods for determining demographic parameters. It is noted the methods (CEMP A4) as published in CEMP Standard Methods 2003 appear adequate. Revision may be required in the future following consideration of how aspects of predator demographics may be used for management in the CCAMLR context. The considerable tagging and search effort required to obtain demographic data and the period over which such effort needs to be sustained is described.
