Calculate age at maturity

Source: R/age_mat.R
age_mat.Rd

Uses the growth rate and the size at maturity to calculate the age at maturity

Usage

age_mat(params)

Arguments

params

A MizerParams object

Value

A named vector. The names are the species names and the values are the ages at maturity.

Details

Using that by definition of the growth rate \(g(w) = dw/dt\) we have that $$\mathrm{age_{mat}} = \int_0^{w_{mat}.}\frac{dw}{g(w)}$$

Examples
