Description:The Southwest Fisheries Science Center (SWFSC), Fisheries Resources Division (FRD) hosted a Pacific Sardine Stock Structure Workshop from November 15-17, 2022, in response to comments received from the Pacific Fishery Management Council’s (PFMC’s) Scientific and Statistical Committee (SSC) about the 2021 catch-only assessment update of the northern subpopulation of Pacific sardine completed by FRD scientists. That assessment showed that catches from the Mexico (Baja CA) fleet that were attributed to the northern subpopulation were on the same order as the entire estimated biomass of the northern subpopulation, which led to unrealistic changes to the estimates of recruitment and consequently that update assessment was not accepted for use in management. This renewed discussions about Pacific sardine stock structure and its delineation in the stock assessment and hence how survey and catch data are assembled for assessment purposes. Consequently, the SWFSC hosted this workshop as preparation for the early 2024 benchmark stock assessment for the northern subpopulation of Pacific sardine.
