Water quality management in aquaculture.
Six parameters decide every crop. Miss one for six hours and you can lose the pond. This is the daily workflow that keeps shrimp and fish alive — and how CAMARON automates the alert layer.

The six parameters that decide the crop
Safe ranges are species- and life-stage-dependent. These are typical bands for grow-out.
Dissolved Oxygen (DO)
Safe: > 4 mg/L (shrimp) · > 3 mg/L (tilapia)
Overnight crashes are the #1 cause of mass mortality. Continuous DO with a 3 mg/L predictive warning saves crops.
pH
Safe: 7.5 – 8.5
Swings > 0.5 in 24h stress every species. Buffer with agricultural lime; log daily AM + PM.
Temperature
Safe: 28 – 32 °C (vannamei) · 26 – 30 °C (tilapia)
Every 1 °C rise doubles metabolic demand and drops DO saturation. Delta-T > 5 °C air↔water = feeding cutback.
Salinity
Safe: 10 – 25 ppt (brackish shrimp) · 0 – 5 ppt (freshwater)
Post-monsoon dilution shocks PL. Adjust stocking to observed salinity, not label salinity.
Total Ammonia Nitrogen (TAN)
Safe: < 1 mg/L (unionised NH₃ < 0.05 mg/L)
Toxicity rises sharply above pH 8.5. Test 2x/week — daily during heavy feed periods.
Nitrite (NO₂⁻)
Safe: < 1 mg/L (shrimp) · < 0.5 mg/L (fish)
Nitrite spikes 2–3 weeks after biofilter disturbance. Add fresh probiotics and reduce feed 20% for 48h.
The daily monitoring workflow
Log DO, temperature, pH. Overnight DO minimum tells you if aerators need overnighting.
Salinity + Secchi (visibility) reading. Photosynthesis is peaking — pH will rise 0.5–1.0 through the day.
TAN check on high-feed ponds. Reduce ration if TAN > 1 mg/L or unionised NH₃ > 0.05 mg/L.
Confirm all aerators are running for the night. Log any observations (foam, colour change, jumping).
Deep dives
Six long-form guides — one per parameter cluster. Each covers safe ranges, mechanism, monitoring routine and response playbook.
Dissolved oxygen management in shrimp & fish ponds
Why overnight DO crashes are the #1 cause of mass mortality, and the aeration + monitoring routine that prevents them.
Read the guidepH and alkalinity: buffering the daily swing
How photosynthesis and respiration swing pond pH by 1.0+ units a day, and how alkalinity buffering keeps species safe.
Read the guideThe ammonia → nitrite → nitrate cycle in aquaculture
How nitrogen from feed and waste moves through your pond, why nitrite spikes 2–3 weeks after a biofilter disturbance, and how to bring it down safely.
Read the guideSalinity management for brackish and freshwater ponds
Post-monsoon dilution shocks post-larvae. Match stocking and acclimation to observed salinity — not label salinity — to protect crops.
Read the guideWater temperature, Delta-T, and feeding decisions
Every 1 °C rise doubles metabolic demand and drops DO saturation. Delta-T > 5 °C between air and water means it's time to cut feed.
Read the guideAlgae blooms, Secchi depth, and turbidity control
A healthy bloom feeds the pond; a crashing bloom kills it. Manage Secchi depth, plankton diversity, and turbidity through daily observation.
