The demersal shelf rockfish (DSR) complex (yelloweye, quillback, copper, rosethorn, China, canary, and tiger rockfish) is a Tier 4 complex and assessed on a triennial cycle, with a full stock assessment typically conducted every third year. This is a partial assessment; a full assessment will be presented in 2021. The DSR complex assessment is based on relative abundance estimates from a remotely operated vehicle, prior to 2012 estimates were made via a manned submersible (Delta). Three management areas (SSEO, CSEO, and NSEO) were surveyed in 2018. The recommended acceptable biological catch (ABC) and overfishing level (OFL) for this assessment includes results from the most recent surveys.
