Details

Function Recruits() As Double Compute factor to convert calculated spawner equivalent production to age cohort (source is PSC Chinook Model).

Tmp = 0 X9 = 1 - NatMort(1) For Age X9 = X9 * (1 - NatMort(Age Tmp = Tmp + X9 * MatRate(Age X9 = X9 * (1 - MatRate(Age Next Age Recruits = Tmp

End Function The SR function gets us the AEQRecruits from spawners in year t. We needs to then translate that to age 1 indiv in pop (Cohort[1]) We know AEQRecruit. How many Age 1 individuals does that translate to? Age1 * (1- total fraction lost) = AEQRecruits So Age1 = AEQRecruits/(1-total fraction lost) Tmp here is total fraction of age 1 ind that eventually return AEQRecruits/Tmp = Age 1 or Cohort[1]

Value

Recruits at age 1
