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

Calculate yield per recruit with a given fishing mortality value.

Description

Calcu_YPR calculates yield per recruit from the statistics derived from the Calcu_stat function and input data with a given fishing mortality value.

Usage

Calcu_YPR(Fish_mort, M, Sel, w, g, A = 6, method = "Baranov")

Arguments

Fish_mort	Fishing mortality to calculate yield per recruit. 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.
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".

Value
