Fdem: Demographic FMSY method

Description

FMSY is calculated as r/2 where r is calculated from a demographic approach (inc steepness). Coupled with an estimate of current abundance that gives you the OFL.

Usage

Fdem(x, DLM_data, reps = 100)

Arguments

x
A position in data-limited methods data object
DLM_data
A data-limited methods data object
reps
The number of TAC samples

Details

Made up for this package. This uses Murdoch McAllister's demographic r method to derive FMSY (r/2) and then makes the quota r*current biomass / 2. Easy.
