Every commercial RAS needs backup for the systems that can kill fish within minutes: power (generators with automatic switch-over), emergency oxygen, duplicate pumps and blowers, and 24/7 alarms on oxygen, level and temperature.
Why redundancy matters
In a RAS, fish depend completely on machines. A power failure or pump stop can cause oxygen to fall to lethal levels in a short time at high stocking densities. Backup systems are insurance, not extras.
Minimum backup list
Standby generators sized for critical loads, with automatic transfer
Liquid or bottled emergency oxygen with automatic diffusers
N+1 pumps and blowers on critical circuits
Separate production units so one failure does not affect the whole farm
Alarms by phone and SMS for oxygen, water level, temperature and power
Spare parts on site for critical equipment
How to check it in supplier quotes
Ask each supplier to list exactly which equipment is duplicated, how long the farm can survive a power cut, and how alarms are delivered. Put these items in the scope so they cannot be removed to lower the price.
Frequently asked questions
At commercial densities it can be only minutes to tens of minutes without oxygen backup. With emergency oxygen, fish can be protected much longer while generators start.

Equipment scope
What equipment does a commercial aquaculture project actually need?
A grow-out project typically needs holding infrastructure (tanks, ponds or cages), water movement (pumps, piping, valves), aeration or oxygenation, water treatment appropriate to the system, feeding equipment, grading and handling gear, monitoring and alarms, and backup power. RAS adds mechanical filtration, biofiltration, degassing, disinfection and tighter process control. Hatchery and processing scopes are specified separately.
Which equipment should be specified before requesting quotes?
Specify the items whose sizing changes everything downstream: design biomass and stocking density, water exchange or recirculation rate, oxygen demand at peak temperature, and installed pumping head. With those four fixed, suppliers can quote aeration, filtration, pumps and power on the same basis. FishMatch calculators produce these figures and attach them to the RFQ.
Can equipment be sourced in stages?
Yes, and phased procurement is common. The usual sequence is water supply and holding infrastructure, then aeration and treatment, then automation and monitoring, then processing and cold chain. Staging works when interfaces and capacity headroom are defined at the start; otherwise later phases force replacement rather than addition.
