setMaxIntakeRate: Set maximum intake rate
Description
Set maximum intake rate
Usage
setMaxIntakeRate(params, intake_max = NULL, reset = FALSE, ...)getMaxIntakeRate(params)
intake_max(params)
intake_max(params) <- value
Value
setReproduction(): A MizerParams object with updated maximum
intake rate.
getMaxIntakeRate() or equivalently intake_max(): An array
(species x size) with the maximum intake rate.
Arguments
- params
MizerParams
- intake_max
Optional. An array (species x size) holding the maximum intake rate for each species at size. If not supplied, a default is set as described in the section "Setting maximum intake rate".
- reset
![[Experimental]](figures/lifecycle-experimental.svg?package=mizer&version=2.5.3)
If set to TRUE, then the intake rate will be reset to the value
calculated from the species parameters, even if it was previously
overwritten with a custom value. If set to FALSE (default) then a
recalculation from the species parameters will take place only if no
custom value has been set.- ...

Setting maximum intake rate
The maximum intake rate \(h_i(w)\) of an individual of species \(i\) and
weight \(w\) determines the feeding level, calculated with
getFeedingLevel(). It is measured in grams/year.
If the intake_max argument is not supplied, then the maximum intake
rate is set to $$h_i(w) = h_i w^{n_i}.$$
The values of \(h_i\) (the maximum intake rate of an individual of size 1
gram) and \(n_i\) (the allometric exponent for the intake rate) are taken
from the h and n columns in the species parameter dataframe. If
the h column is not supplied in the species parameter dataframe, it is
calculated by the get_h_default() function.
If \(h_i\) is set to Inf, fish of species i will consume all encountered
food.
