Stock assessment of American Samoa bottomfishes, 2023 (ID469)

The Western Pacific Regional Fishery Management Council’s fishery ecosystem plan for American Samoa includes 11 bottomfish management unit species (BMUS) that have traditionally been assessed and managed as a group (i.e., a species complex). The previous 2019 assessment concluded this complex was both undergoing overfishing and was overfished. The current benchmark assessment for the American Samoa BMUS differs significantly from all previous efforts in terms of data inputs and model structure. A major improvement for this new benchmark was the move to single-species, age-structured models in the Stock Synthesis modeling framework for all BMUS. In the terminal year of the model, 2021, all nine BMUS stock statuses were not overfished and overfishing was not occurring (see Figure S1 below). Overfishing is defined by fishing mortality (F) in 2021 being higher than FMSY and overfished status is defined by spawning stock biomass (SSB) in 2021 being lower than SSB at the Minimum Stock Size Threshold.
