Simple fixed F harvest control rule

Source: R/HCRs.R

A simple control rule that explicitly specifies the target apical F independent of any model.

HCR_fixedF(Assessment, reps = 1, Ftarget = 0.1)

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 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"))
#> ✔ Checking MPs
#> Error: Some MPs are not a functions of class `MP`: F0.2
# }
