A two dimensional array (predator species x predator size) with the feeding level.
The feeding level \(f_i(w)\) is the
proportion of its maximum intake rate at which the predator is actually
taking in fish. It is calculated from the encounter rate \(E_i\) and the
maximum intake rate \(h_i(w)\) as
$$f_i(w) = \frac{E_i(w)}{E_i(w)+h_i(w)}.$$
The encounter rate \(E_i\) is passed as an argument or calculated with
getEncounter(). The maximum intake rate \(h_i(w)\) is
taken from the params object, and is set with
setMaxIntakeRate().
As a consequence of the above expression for the feeding level,
\(1-f_i(w)\) is the proportion of the food available to it that the
predator actually consumes.
The feeding level is used in mizerEReproAndGrowth() and in
mizerPredRate().
