Historical-class: Class '"Historical"'

In salmonMSE: Management Strategy Evaluation for Salmon Species

Class "Historical"

Description

Optional component of the operating model that specifies the historical dynamics. The default option starts the projection with 1000 natural-origin juveniles and 1000 hatchery-origin juveniles (if there is hatchery production) in the oldest age class, representing single-brood year returns since there is only one age class in the population. Specify the abundance in all age class to simulate multiple brood-year returns.
