# Mean Catch Depletion

`MCD.Rd`

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

## 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
