R_fxn: Ration function

In coreyphillis/fisHeat: A Bioenergetics Model for Predicting Juvenile Salmon Growth

Description

Calculate the ration available to a fish given a consumption rate, foraging time, and prey dry mass. Available ration is relative to the temperature- and mass-dependent ration that maximizes growth. When ration >1 fish are satiated and food is not limiting to growth; when ration <1 food is limiting.

Usage

R_fxn(
  foraging_time = FORAGING_TIME,
  consumption_rate,
  dry_mass = DRY_MASS,
  Temperature,
  M0,
  ...
)

Arguments

foraging_time	time (in minutes) a fish forages. Default = 360
consumption_rate	calculated with typeII function
dry_mass	dry mass (in ___) of prey
Temperature	water temperature (in C)
M0	initial fish mass (in grams)
