Overview
Overview
SGT Smart Aquaculture is an end-to-end pond and tank monitoring platform — solar buoy sensors that measure dissolved oxygen, pH, ammonia, temperature, salinity and turbidity; edge-controlled aerators and feeders; AI-based biomass estimation; and a farmer-friendly mobile app.
Built for shrimp, tilapia, pangasius, carp and trout operations across Bangladesh, India, Vietnam and the Philippines. The system increases yield by 8-20% and cuts mortality 30-60% by maintaining ideal water quality and preventing overnight oxygen crashes.
- Multi-parameter sensing — DO, pH, NH3, temperature, salinity, turbidity in one buoy
- Edge-controlled aerators & feeders — rules fire even when the cloud is unreachable
- AI biomass estimation — ±4% accuracy via camera + feed-response model
- Mortality alerts — overnight oxygen crash protection saves entire harvests
How It Works
- Sense — a solar-powered buoy with a probe stack samples water every 10-30 seconds at multiple depths.
- Decide — edge rules run locally on the buoy (e.g.,
IF DO < 5.0 mg/L → aerator ON) and trigger actuators in real time. - Act — relays control paddle-wheel or diffused aerators, auto-feeders, water-exchange pumps and heaters.
- Report — readings stream to the cloud, where AI estimates biomass, FCR and predicts harvest date; the farmer sees everything in a phone app and gets push alerts on alarms.
Features
- Water-quality sensors — DO ±0.1 mg/L, pH ±0.05, NH3 ±0.02 mg/L, temp ±0.2 °C
- Edge control — local if/then rules, offline operation, AES-128 encrypted radio
- Auto-feed scheduler — by time, by biomass, or by demand (camera + appetite model)
- Aerator orchestration — multi-aerator staggering reduces electric peak load
- Biomass & FCR estimation — camera + feed model; ±4% biomass, ±0.05 FCR
- Multi-pond dashboards — fleet view, per-pond drill-in, historic trends
- Push / SMS / IVR alerts — works in rural areas, multi-language
- Daily report PDF — emailed every morning with overnight events and KPIs
Use Cases
- Shrimp farming — intensive ponds where DO crashes can wipe out a cycle
- Tilapia / pangasius — high-density cage and pond culture
- Carp polyculture — multi-species ponds with seasonal stocking
- RAS / indoor systems — recirculating aquaculture with tight tolerance
- Hatcheries — temperature and ammonia compliance for larval stages
- Trout / cold-water — heater / chiller control with strict temperature bands
