In ShotaNishijima/frasam: Fisheries Research Agency (FRA) provides an R package for analyzing the State-space Assessment Model (SAM)
Calcu_SBmsy R Documentation
Calculate the spawning stock biomass at the maximum sustainable yield (SSBmsy).
Description
Calcu_SBmsy calculates the spawning stock biomass at the maximum sustainable yield (Fmsy) for the Bevertoh-Holt stock-recruitment relationship.
Usage
Calcu_SBmsy(Fmsy, M, Sel, w, g, A = 6, alpha, beta, method_SR)
Arguments
M
A vector of natural mortality rate at age a. The length should be A+1.
Sel
A vector of selectivity at age a. The length should be A+1.
w
A vector of weight at age a. The length should be A+1.
g
A vector of maturity at age a. The length should be A+1.
A
Plus group age. Default is 6.
alpha
Estimated Parameter alpha in the Beverton-Holt stock recruitment relationship.
beta
Estimated Parameter beta in the Beverton-Holt stock recruitment relationship.
Value
A value of the spawning stock biomass at the maximum sustainable yield (SSBmsy).
