Ammonia Nitrogen Spike Detection in Closed-Loop Aquaculture: Sensor Strategies from Shanghai ChiMay
Closed-loop and recirculating aquaculture systems (RAS) live and die by the nitrogen cycle. Total ammonia nitrogen (TAN) rises with every feeding event and every unit of fish biomass, and it falls only as fast as the nitrifying biofilter can convert it. When a biofilter is destabilized—by cold water, chlorine slug, antibiotic dosing, or overfeeding—TAN can…
