Calculate F0.1 value.

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.
