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 yield per recruit.

Description

Calcu_Fmax calculates the fishing mortality that maximizes the yield per recruit.

Usage

Calcu_Fmax(M, Sel, w, g, A = 6, F_max = 10, method = "Baranov")

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.
F_max	Maximum value of F values to be searched for determining F%SPR. This value should be large enough so that the true F%SPR value be included. Default is 10
method	Method of the fishing equation. Either "Baranov" or "Pope" is allowed. Default is "Baranov".

Value

A value of the F that maximizes the yield per recruit.
