The situation today

Public figures — tap the small number to open the source.

>954 t of fish

died from low oxygen (Hải Dương, Mar–Apr 2024); DO measured 2–3 mg/l, some below 2[12]

>454 ha of shrimp

lost, ~270 million animals, in a 35–39°C heatwave (Trà Vinh, Apr 2025); advice: check temperature, pH and oxygen weekly and run aerators[17]

Current problems

Oxygen crashes at night

Algae respiration, sultry weather, still water — found only at dawn.

Infrequent water checks

Test kits every few days miss swings within the day.

Paper pond logs

Feeding, treatments, water checks and losses not tied to ponds or crops.

Buyers want traceability

Exports need pond history, treatments and withdrawal times.

How NextFarm solves it

Scenario: One night on a 3-pond lined shrimp farm

  1. 21:00

    Sultry night; pond 2 DO trending down on the chart.

  2. 01:40

    Pond 2 DO below threshold: the Gateway starts 2 more aerators and alerts the night worker.

  3. 05:30

    DO back in range; the assistant logs the event and suggests a lighter morning feed.

What you can measure after a season

The software doesn't promise yields; it gives you numbers to compare before and after.
