A simple control rule that explicitly specifies the target apical F independent of any model.
Arguments
- Assessment
An object of class Assessment with estimates of next year's abundance or biomass.
- reps
The number of replicates of the TAC recommendation (not used).
- Ftarget
The value of F.
Value
An object of class MSEtool::Rec with the TAC recommendation.
Details
The catch advice is calculated using the catch equation of the corresponding
assessment. See Assessment@forecast$catch_eq, a function that returns the catch advice for a specified Ftarget.
Examples
# create an MP to run in closed-loop MSE (fishes at F = 0.2)
F0.2 <- make_MP(SP, HCR_fixedF, Ftarget = 0.2)
# \donttest{
myOM <- MSEtool::runMSE(MSEtool::testOM, MPs = c("FMSYref", "F0.2"))
