Abstract

This paper follows from requests made at the last Demersal Working Group meeting for further calculations relating to determination of whether the 2008 west coast survey results corresponded to anomalous circumstances, and so should not be included in OMP computations of the TAC for 2009. The paper first checks whether OMP inputs for the last two years have been within the range projected when the OMP was agreed in 2006. Then it compares differences between west coast survey and CPUE results for adjacent periods to check whether these show any evidence of an anomaly for the 2008 west coast survey.
