What it is
A power cut can stop the main oxygen supply to a stocked pond. The risk depends on biomass, weather and existing DO. Treat an outage as urgent instead of guessing how long the pond can wait.
Signs to watch for
- Stopped aerators or a power alarm.
- A falling DO reading.
- Weak shrimp or crowding at the edges as oxygen falls.
Common causes
- Grid power is interrupted.
- An electrical fault or motor problem stops equipment.
- The backup generator, fuel supply or changeover system is not ready.
How to confirm the cause
- Check the DO meter and confirm which aerators stopped from a safe position.
- Have a qualified electrician check faults; do not open live panels or stand in water near electrical equipment.
What to do immediately
- 1
Use the tested backup supply and safe backup aeration. Only trained people should operate electrical changeover equipment.
- 2
Measure DO at representative locations. Ask for urgent technical help if aeration cannot be restored.
- 3
Pause feed while oxygen support is interrupted; avoid handling shrimp or adding inputs.
- 4
Keep checking shrimp and DO until aeration is stable. If oxygen falls or deaths start, follow the low-DO guide immediately.
Prevention: your practical checklist
- Test backup equipment under its intended load with trained staff.
- Keep a safe fuel and maintenance plan and an accessible emergency contact list.
- Assign a person to respond to outages, especially at night.
When to call an expert
- Call immediately if no working aeration or backup is available for a stocked pond.
- Call an electrician for damaged cables, sparks or wet electrical equipment; keep others clear.
Farmer questions
How long can shrimp survive without aerators?
There is no safe universal number. Biomass, water condition, temperature and starting DO change the risk. Restore safe aeration and measure DO rather than waiting for a fixed time.
Should I keep feeding during the outage?
Pause feed while oxygen support is interrupted. Resume with a technician’s advice after DO and shrimp activity recover.
Can I repair the wiring myself?
Do not attempt live electrical repairs. Keep people out of the water near faulty equipment and call a qualified electrician.
