MCD: Mean Catch Depletion

In DLMtool: Data-Limited Methods Toolkit

Mean Catch Depletion

Description

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

Usage

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?

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.

Value

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

Functions

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

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