blim-FLBRP-method: Calculate Biomass Limit Reference Points

In laurieKell/FLCandy: Candidate methods for FLR

Calculate Biomass Limit Reference Points

Description

Calculates biomass limit reference points (Blim) based on a ratio of virgin recruitment for an FLBRP object

Usage

## S4 method for signature 'FLBRP'
blim(object, ratio = 0.3)

Arguments

object	An FLBRP object containing stock-recruitment parameters
ratio	Numeric value between 0 and 1 indicating the fraction of virgin recruitment to use for Blim calculation (default: 0.3)

Details

The method:

• Extracts virgin recruitment from reference points

• Applies the specified ratio to calculate Blim recruitment

• Computes associated reference points (harvest, yield, SSB, biomass, etc.)

Value

An FLPar object containing Blim reference points with the following quantities:

• harvest: Fishing mortality at Blim

• yield: Catch at Blim

• rec: Recruitment at Blim

• ssb: Spawning Stock Biomass at Blim

• biomass: Total biomass at Blim

• revenue: Revenue at Blim

• cost: Cost at Blim

• profit: Profit at Blim

Examples

## Not run: 
data(ple4)
brp <- FLBRP(ple4)
blim_ref <- blim(brp, ratio=0.3)

## End(Not run)
