wcrfish-barotrauma

This analysis incorporates new data to estimate depth-specific barotrauma mortality rates for West Coast rockfish species. The initial analysis was conducted in 2014 by the Groundfish Management Team to the Pacific Fishery Management Council to estimate depth-specific barotrauma mortality rates for canary rockfish, yelloweye rockfish, and cowcod. This analysis follows the methodology used in 2014 where a hierarchical meta-analysis is applied to estimate barotrauma mortality within each pre-determined depth bin. The final analysis is publicly available online. The discard mortality rates with the use of descending devices recommended for use by management by the Groundfish Mortality Team were adopted by the Pacific Fishery Management Council at the November 2022 meeting.
