initial_effort {mizer}R Documentation

Initial fishing effort

Description

The fishing effort is a named vector, specifying for each fishing gear the effort invested into fishing with that gear. The effort value for each gear is multiplied by the catchability and the selectivity to determine the fishing mortality imposed by that gear, see setFishing() for more details. The initial effort you have set can be overruled when running a simulation by providing an effort argument to project() which allows you to specify a time-varying effort.

Usage

initial_effort(params)

initial_effort(params) <- value

validEffortVector(effort, params)

Arguments

params

A MizerParams object

value

A vector or scalar with the initial fishing effort, see Details below.

effort

A vector or scalar with the initial fishing effort, see Details below.

Details

A valid effort vector is a named vector with one effort value for each gear. However you can also supply the effort value in different ways:

These conversions are done by the function validEffortVector().

An effort argument will lead to an error if it is either

Value

Effort vector
