Race way system
Water supply system
Raceways are designed to provide flow, through for culturing very dense populations of fish. An abundant flow of good quality water is essential to provide for the health of the animals and to flush wastes from the system. Water quality in a raceway is maintained by manipulation of the water flow rate and by adjusting other water treatment processes. Water quality tends to vary along the long axis of a raceway and a distinct degradation of conditions is evident between the inlet and outlet. The specific flow rate required meeting the oxygen demand of the fish and flushing of metabolites is determined by the influent water temperature and dissolved oxygen concentration and by the oxygen consumption and ammonia excretion of the fish in the raceway.
