Aquaculture Aquaculture Water Quality

Continuous water flow in raceways can prevent toxic buildup but demands precise management

0

Why is continuous water flow critical in raceway aquaculture systems for maintaining water quality?

It prevents the accumulation of toxic wastes and maintains adequate oxygen levels for aquatic organisms. It primarily helps in feeding fish more efficiently by circulating food particles. Continuous flow is mainly to keep the water temperature constant regardless of external conditions.
