A stock assessment benchmark of the Main Hawaiian Islands (MHI) Deep7 bottomfish complex will be conducted through fishing year 2023 by PIFSC scientists. The Deep7 bottomfish fishery is a targeted deep-water bottomfish handline fishery operated off small boats that hold cultural and economic importance for the region. This benchmark assessment incorporated new data in the form of fishery-independent biomass estimates and also followed data filtering recommendations from a series of 5 community workshops that involved fishers, managers, and scientists on best practices for filtering bottomfish commercial catch and effort data from Hawaii state commercial catch reports for use in stock assessments. As part of that series of workshops, individual fishers’ catch reports have been better linked further back in time and this linking is newly applied in this benchmark stock assessment. This assessment used commercial data for the years 1948-2023. It assessed Deep7 bottomfish, by building upon the previous modeling framework from the past four assessments, but with improved data and data filtering as previously described, along with improvements to CPUE standardization, and other modeling approaches. Unreported catch was calculated and included using catch and effort data following methods similar to those applied in previous assessments.
