Calculate predator energy density (Mid-level - Main function) — calculate_predator_energy

Main energy density calculation function called from simulation loop

Usage

calculate_predator_energy_density(weight, day = 1, processed_predator_params)

Arguments

weight: Fish weight (g)
day: Simulation day (for equation 1)
processed_predator_params: List with processed predator parameters

Value

A numeric scalar giving the predator energy density in J per g fish, calculated according to processed_predator_params$PREDEDEQ (1 = interpolated daily data; 2 = piecewise linear by weight; 3 = power function of weight).

Examples

# PREDEDEQ 3: power function of weight
params <- list(PREDEDEQ = 3, Alpha1 = 4800, Beta1 = 0.1)
calculate_predator_energy_density(weight = 100, processed_predator_params = params)
