Update of main indicators of stock status for units 1 and 2 redfish in 2016: Fs70-7/2017-023E-PDF

“The Units 1 and 2 redfish stocks (Sebastes mentella and Sebastes fasciatus) were assessed in March 2016 using survey-based indicators after an assessment model framework meeting in December 2015 rejected both assessment model methods proposed. A new model framework meeting proposed for November 2016 was cancelled after investigations of historical catch cast doubt on official catch statistics from the late-1980s and early-1990s, which represented a period of critical leverage in assessment model fitting. A full assessment was expected in March 2017; however, without an accepted model, this could not be conducted. Therefore a Science Response was requested to update the status of Units 1 and 2 redfish in winter 2017 using the latest data. The present work represents an update of the redfish stocks based on the DFO summer trawl survey conducted since 1984 in Unit 1, and the industry (Groundfish Enterprise Allocation Council or GEAC) survey of Unit 2 conducted since 2000. This Science Response Report results from the Science Response Process of March 16, 2017 on the Updated status of Units 1 and 2 Redfish in 2016"--Context, p. [1].
