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 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 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)
# }
