The quantitative assessment of the South African sardine resource, using data from 1984 to 2018 has been finalised. This two mixing‐component model assumed no stock recruitment relationship during conditioning. The west component abundance was estimated to be about 12% of the historical (1984‐2018) average, with a biomass of 51 thousand tons in November 2018. The south component abundance was estimated to be about 95% of the historical (1984‐2018) average, with a biomass of 560 thousand tons in November 2018. Results are only given at the joint posterior mode.
