Description Usage Arguments Value

View source: R/ImplementationModels.R

Description

Csirke_MacCall's catch pr unit effort (CPUE) model. Assumes that catchability (q) is dependent on abundance (or population density), most often increasing as abundance decrease.

Usage

1
Impl_CM(Effort = 3, alpha = 0.13, beta = 0.1, Pop_state = 10)

Arguments

Effort

defines the effort, that will be multiplied by q to estimate total catch

alpha

Parameter is catchability model

beta

Parameter in catchability model

Pop_state

Population abundance (or biomass)

Value

H_I Number of harvested individuals (or harvested biomass)
