  • Description:
    A full, age-structured assessment is presented for GOA rex sole. In previous years, the biomass estimates of the assessment were used to calculate OFLs and ABCs using a Tier 5 management approach because FOFL and FABC reference points estimated from the assessment were thought to be unreliable. In September 2017, newly available historical fishery age data were added to the assessment that substantially improved reliability of estimates of FOFL and FABC. Therefore, all estimates from the assessment were used to calculate OFLs and ABCs using a Tier 3a management approach for the 2017 assessment. The 2015 model was updated with new data from the previously-used data sources only and OFLs and ABCs were calculated using a Tier 5 management approach and these results are reported in Appendix 6A for comparison with the 2017 model.
