For each species, returns the rate at which biomass is lost due to mortality.

Usage

getZB(params)

Arguments

params

A MizerParams object

Value

A named vector of biomass loss rate due to mortality for each species

Details

This is calculated as $$ZB_i = \int_{w_0}^{w_{max}} \mu_i(w) N_i(w) w dw$$ where \(\mu_i(w)\) is the mortality rate of an individual of species \(i\) and weight \(w\) (calculated with getMort) and \(N_i(w)\) is the number density of species \(i\) at weight \(w\).
