2.1 Number at Age

2.1.1 Initial

• annual
• seasonal - initialized to account for seasonal recruitment

Notes:

• age of recruitment is MinAge(Stock)
• MinAge(Stock) == 0 means that recruitment occurs in same time step as SProduction
• otherwise lagged by appropriate number of time steps (year, quarters, months)

\[ N_{t+1} = N_t ... \]
