Recirculating Aquaculture Systems for Atlantic salmon are one of the most technically demanding branches of commercial aquaculture. Success depends on tight coupling of biology, water chemistry and energy engineering.

Land-based RAS today covers three stages: smolt (up to ~120g), post-smolt (up to ~1kg) and full grow-out. Post-smolt RAS reduces sea-time and disease exposure; grow-out RAS decouples production from sea licenses entirely.
Water chemistry (DO, TAN, CO₂, NO₂, NO₃, salinity), temperature stability, and specific energy determine bankability more than any single piece of equipment.
Biological instability during scale-up, off-flavour (geosmin/MIB), and grid outages remain the top three risks. Redundancy planning is not optional.

Short answer
RAS For Salmon affects both project cost and project risk, so it belongs in the specification stage rather than the purchasing stage. This page sets out what commercial buyers assess, what typically drives cost and lead time, and which questions to put to suppliers before signing. You can turn any of it into a confidential RFQ in a few minutes.
Before you request quotes
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.
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.
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.
