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

Calculate spawning biomass per recruit (SBR) with a given fishing mortality value.

Description

Calcu_SBR calculates SBR from the statistics derived from the Calcu_stat function and input data with a given fishing mortality value.

Usage

Calcu_SBR(Fish_mort, M, Sel, w, g, 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.
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.

Value

A value of spawing biomass par recruit with the given fishing mortality.
