Calculate the relative number at age at the equilibrium.

Calcu_N calculates the relative number at age at the equilibrium (N) with a given fishing mortality value.

Usage

Calcu_N(Fish_mort, M, Sel, A = 6)

Arguments

Fish_mort

Fishing mortality to calculate SBR. Should be provided with a numeric value.

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.

A

Plus group age. Default is 6.
