WOW - fish Welfare and Oxygen in Water
A simple model for oxygen balance in a salmon farm.
Development notes:
Initial DO in mg L-1 (=g m-3)
Cage volume in m3 therefore DO mass per cage is in g m-3 DO X m3 = g DO
Salmon respiration from WinFish: outputs are in mg d-1, converted to g h-1. Used value of 1 g fish-1 h-1 taken from a 2.5 kg fish
Model runs only for 12h as an example. Long runs will take some time because a small timestep is needed so that the model is stable. Also for that reason all rates are parameterized per hour, and water inflow is calculated per hour.
A slider was added to allow the user to define the number of fish in a cage (from 50k to 150k).
Flow is currently only advection in X, and unidirectional.
