MCD: 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 a data-limited methods data object

Data

A data-limited methods data object

reps

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

plot

Logical. Show the plot?

Value

An object of class Rec 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

Required Data

See '>Data for information on the Data object

MCD: Cat, Dep

MCD4010: Cat, Dep

Rendered Equations

See Online Documentation for correctly rendered equations

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.

Examples

# NOT RUN {
MCD(1, DLMtool::Atlantic_mackerel, plot=TRUE)
MCD4010(1, DLMtool::Atlantic_mackerel, plot=TRUE)
