In ShotaNishijima/frasam: Fisheries Research Agency (FRA) provides an R package for analyzing the State-space Assessment Model (SAM)

Calculate the fishing mortality that maximizes the maximum sustainable yield (Fmsy) with fixed steepness parameters (h) in the Bevertoh-Holt stock-recruitment relationship.

Description

Calcu_Fmsy calculates the fishing mortality that maximizes the maximum sustainable yield (Fmsy) with fixed steepness parameters (h).

Usage

Calcu_Fmsy(M, Sel, w, g, A = 6, method, F_max = 10, 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.
method	Method of the fishing equation. Either "Baranov" or "Pope" is allowed.
F_max	Maximum value of F values to be searched for determining Fmsy.
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 F that maximizes the yield per recruit.
