Nutrient Regeneration Functions for FB4 Model

Experimental functions for computing daily nitrogen (N) and phosphorus (P) fluxes in fish using a mass-balance approach consistent with ecological stoichiometry theory. For each element the daily budget is:

$$\text{Consumed} = \text{Assimilated} + \text{Egested}$$ $$\text{Assimilated} = \text{Growth} + \text{Excreted}$$

Assimilation efficiencies for N and P are species- and prey-specific and can differ from those used for energy.
