Abstract:
The effects of updates on the operating model are examined. Because of the new growth schedule
and the most recent two years’ data, the operating model prefers somewhat higher steepness
compared to the previous version. This difference has little influence on the historical trajectories
of spawning stock biomass, but it leads to more optimistic projection results.
