Shoal
Aquaculture pond monitoring for tilapia health and water conditions — dissolved oxygen, temperature, and pH tracked for early stress detection.
Problem
Tilapia ponds crash quietly when dissolved oxygen collapses overnight. Shoal monitors water chemistry and temperature so operators can aerate or adjust feed before fish stress becomes mortality.
What it covers
- Dissolved oxygen, pH, and temperature sensing at depth
- Aerator recommendations from threshold rules
- Pond-level dashboards with nightly minimum DO tracking
- SMS/local alarm hooks for caretakers without smartphones
