RAS vs Pond Farming
RAS delivers premium yields with minimal water use; ponds win on CAPEX and simplicity. The right answer depends on species, market and climate.
| Criterion | RAS (Recirculating) | Pond Farming |
|---|---|---|
| CAPEX per ton/yr | $15k–$25k | $2k–$6k |
| OPEX per kg | $3.5–$5.5 (energy-heavy) | $1.2–$2.5 (feed-dominant) |
| Water use | 95–99% recycled | High evaporation + exchange |
| Stocking density | 60–120 kg/m³ | 1–5 kg/m³ |
| Biosecurity | Excellent (closed) | Moderate |
| Climate independence | Year-round, any climate | Climate / season dependent |
| Best for | Salmon smolt, premium trout, urban supply | Tilapia, catfish, shrimp at scale |
Use RAS for premium species, biosecurity-critical projects and water-scarce regions. Use ponds for low-cost protein at scale in suitable climates.

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.
Supplier selection criteria
How should a buyer compare aquaculture suppliers?
Compare on evidence, not on presentation: delivered projects at a similar scale and climate, engineering support during design, lead time commitments, spare-part and service availability in your region, certification and testing documentation, payment and warranty terms, and willingness to quote against your specification rather than substituting a catalogue package.
What are the warning signs in a supplier quotation?
Treat these as review triggers: no itemised scope, guaranteed biological or financial performance, no named delivery terms or lead time, no spare-parts or service statement, unclear responsibility for installation and commissioning, and equipment sizing that does not reference your water temperature, oxygen demand or biomass targets.
How does FishMatch handle supplier selection?
FishMatch is an independent sourcing layer, not a manufacturer or reseller. Requirements are structured into a single technical RFQ and routed to relevant producers; buyers receive comparable offers without supplier identities being exposed before they choose to proceed. Selection stays with the buyer — FishMatch standardises the comparison basis.
