A simple average catch-depletion MP that was included to demonstrate just how informative an estimate of current stock depletion can be.

MCD(x, Data, reps = 100, plot = FALSE)

MCD4010(x, Data, reps = 100, plot = FALSE)

Arguments

x

A position in the data object

Data

A data object

reps

The number of stochastic samples of the MP recommendation(s)

plot

Logical. Show the plot?

Value

An object of class Rec-class with the TAC slot populated with a numeric vector of length reps

Details

The TAC is calculated as: $$\textrm{TAC} = 2 \bar{C} D $$ where \(\bar{C}\) is mean historical catch, and \(D\) is estimate of current depletion.

The TAC is modified by a harvest control rule in MCD4010.

Functions

  • MCD: The calculated TAC = 2 \* depletion \* AvC

  • MCD4010: Linked to a 40-10 harvest control rule
