Calculates the OFL based on a fixed ratio of FMSY to M multiplied by a
current estimate of abundance.
Usage
Fratio(x, DLM_data, reps = 100)
Arguments
x
A position in a data-limited methods data object
DLM_data
A data-limited methods data object
reps
The number of samples of the TAC recommendation
Value
A numeric vector of TAC recommendations
Details
A simple method that tends to outperform many other approaches alarmingly
often even when current biomass is relatively poorly known. The low stock
crash potential is largely due to the quite large difference between Fmax
and FMSY for most stocks.
