How much oxygen do fish need?
As a rule of thumb, one tonne of fish consumes about 0.3–0.5 kg of oxygen per hour while feeding, dropping to 0.15–0.25 kg/h at rest. Warm water and the hours after feeding set the design point, which is why night-time oxygen risk — not daily average demand — decides aeration and emergency oxygen sizing.
What we source
FishMatch Group sources pure-oxygen supply systems — PSA / VPSA generators, liquid-oxygen (LOX) plants, oxygen cones, low-head oxygenators (LHO) and diffuser systems — for RAS, intensive raceways and cage top-up.
- PSA & VPSA O₂ generators
- LOX tanks & vaporizers
- Oxygen cones & LHO
- Fine-bubble diffusers
- DO monitoring & control
Private by design.
You'll never see supplier names. We run a sealed-bid process and present anonymized proposals — you choose the winner, we handle the introduction and the contract.
Markets we source oxygen systems for
Sourcing runs the same way in every market: one structured specification, matched suppliers with real export experience for that destination, and anonymized bids priced on the same scope. Country pages below carry the local logistics, certification and installation detail.
Covers oxygen generators and oxygen tanks for aquaculture, fish farming and hatcheries — including oxygen systems for broodstock, hatcheries and salmon farming.
Norwegian suppliers are an established source of oxygenation for salmon RAS and sea sites. Compare aquaculture equipment suppliers in Norway in one supplier-neutral RFQ.
Oxygen Systems: equipment guides and planning tools
Product-type guides explain what each item does, published specification ranges and what to put in a request. Size the project with the calculators, then send one reviewed RFQ.
- Oxygen cones
Pressurised contactors that dissolve pure oxygen into a side-stream.
- Oxygen generators (PSA/VPSA)
On-site oxygen from air, with liquid oxygen as backup.

Before you request quotes
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.
