Calculate the fishing mortality that maximizes the yield per recruit.

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.
