GB_CC: Geromont and Butterworth Constant Catch Harvest Control Rule

Description

A simple MP that aims for average historical catches (as a proxy for MSY) subject to imperfect information.

Usage

GB_CC(x, Data, reps = 100)

Arguments

x

A position in data-limited methods data object

Data

A data-limited methods data object

reps

Details

Note that this is my interpretation of their MP and is now stochastic. Currently it is generalized and is not 'tuned' to more detailed assessment data which might explain why in some cases it leads to stock declines.
