Sheperd stock-recruitment function

Edit this page.   Source: R/MizerParams-class.R

Takes the rates \(R_p\) of egg production and returns reduced, density-dependent rates \(R\) as $$R = \frac{R_p}{1+(b\ R_p)^c}$$

srrSheperd(rdi, species_params)

Arguments

rdi

Vector of density independent egg production rates \(R_p\) for all species.
species_params

A species parameter dataframe. Must contain columns sheperd_b and sheperd_c with the parameters b and c.

Value

Vector of density-dependent larvae production rates.
