calc_pwild_age: Proportion wild spawners

In salmonMSE: Management Strategy Evaluation for Salmon Species

Proportion wild spawners

Description

Calculate the proportion of wild spawners from a time series of spawners

• calc_pwild() is the simple calculation based on the proportion of hatchery spawners

• calc_pwild_age() performs the calculation weighted by age class fecundity

Usage

calc_pwild(pHOS_cur, pHOS_prev, gamma)

calc_pwild_age(NOS_a, HOS_a, fec, gamma)

Arguments

pHOS_cur	Numeric, proportion of hatchery spawners in current generation
pHOS_prev	Numeric, proportion of hatchery spawners in previous generation
gamma	Numeric, reduced reproductive success of hatchery spawners
NOS_a	Array ⁠[nsim, maxage, years]⁠ for natural spawners
HOS_a	Array ⁠[nsim, maxage, years]⁠ for hatchery spawners
fec	Array ⁠[nsim, maxage, years]⁠ for age class fecundity

Value

calc_pwild_age() a matrix of pWILD by simulation and year. calc_pwild() returns a numeric

Examples

calc_pwild(0.9, 0.4, 0.8)
