Short‐ and long‐term projections of the sardine resource are considered under alternative constant catch scenarios. Recruitment to the west component is estimated to be the primary driver of the population as a whole, and thus management considerations focus on the west component. The west component effective spawner biomass is estimated to be of a similar size to that estimated a year ago, but increases to this biomass are projected to be substantially less optimistic than those projected a year ago, while it is possible that the west component total biomass may decrease between November 2019 to November 2020, even under a no catch scenario.
