What it is
An outage can interrupt air, pumping and temperature control together. Risk differs between tanks and life stages. Use a tested emergency plan rather than a fixed waiting period.
Signs to watch for
- Blower or pump stops; an alarm activates.
- Air flow fails in one line or across the hatchery.
- DO falls or animals become weak.
Common causes
- Power failure or a mechanical fault.
- A damaged or blocked air line.
- Backup equipment, fuel or changeover is not ready.
How to confirm the cause
- Identify which tanks lost air and check DO safely.
- Ask trained staff to check the supply and equipment; do not open live panels.
What to do immediately
- 1
Activate the tested backup system using trained staff. Never run a fuel-powered generator in an enclosed room.
- 2
Keep people clear of wet electrical equipment and call a qualified electrician for faults.
- 3
Check DO and animal condition in affected tanks. Adjust feed only with the technician’s stage-specific plan.
- 4
Record the outage and check recovery after restart; watch tanks that lost circulation or temperature control.
Prevention: your practical checklist
- Load-test backup equipment and document maintenance.
- Keep protected air lines, safe fuel arrangements and response contacts.
- Assign an outage responder for every shift.
When to call an expert
- Call immediately if air cannot be restored or animals show distress.
- Keep clear and obtain electrical help for sparks, burning smells or damaged cables.
Farmer questions
How long can a tank wait without air?
There is no universal safe time. Stage, biomass, temperature and starting oxygen all matter. Restore the planned air supply and measure DO promptly.
Should all tanks get the same emergency action?
No. A technician should assess the affected systems and stages. Use the documented emergency plan instead of improvising a single treatment for every tank.
Can anyone operate the changeover switch?
Only trained people should operate backup power and changeover equipment. Do not attempt live repairs or work while standing in water.
