Abstract
Corrected Bayesian stock assessment results for breeding stocks D and G which take into account trend information from the IDCR/SOWER survey results are presented. At the 2006 IWC scientific meeting, the authors presented various stock assessments for breeding stocks D and G (Johnston and Butterworth 2006, IWC 2006). Some of the assessment scenarios presented involved fitting to trend information from the IDCR/SOWER circumpolar surveys which was reported in Branch (2006). The authors inadvertently used the raw abundance estimates provided which had not been adjusted for comparability with respect to areal coverage. Corrected assessment results are thus presented here, for which the appropriate IDCR/SOWER survey trend infomration for comparable areas are used.
