Calcu_F0.1: Calculate F0.1 value.

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

Calculate F0.1 value.

Description

Calcu_F0.1 calculates the fishing mortality rate at which the slope of the yield-per-recruit curve is 10% of the slope of the curve at its origin.

Usage

Calcu_F0.1(M, Sel, w, g, A = 6, method = "Baranov", F_max = 10)

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. Default is "Baranov".
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

Value

A value of the F0.1.
