calc_Bprey_agepreferred: Calculate the age-preferred biomass of a prey species...

In jcpayne/mice-models: Model of Intermediate Complexity for Ecosystem Assessment

Description

A utility function that calculates the biomass (tons) of prey species X that is available to predator species Y, as: (biomass-at-age of prey) x (predator preferences for prey age classes). This function returns an intermediate product in the calculation of total available prey biomass. Note: this is akin to Punt et al's use of biomass of age 1+ fish, but allows the predator to eat some of the age-0 fish as well if their age-preferences indicate it.

Usage

calc_Bprey_agepreferred(predator, prey, t)

Arguments

predator	A predator object.
prey	A prey object.
t	Time t.

Value

A biomass value.
