RAS RFQ: From Biomass Plan to Comparable System Proposals
RAS proposals are only comparable when the biological load and the treatment duty are fixed by the buyer. State the biomass plan, feed load, water budget and redundancy requirement, and suppliers quote engineering rather than brochures.
Short answer
What does a RAS RFQ need to contain?
A RAS RFQ needs species and harvest size, annual production and peak standing biomass, the production and harvest schedule, peak daily feed load, design temperature, make-up water volume and quality with an analysis, target water-quality envelope (oxygen, TAN, nitrite, CO2, TSS, alkalinity, pH), required recirculation rate, redundancy and failure tolerance, effluent and solids handling rules, energy price and grid reliability, plus scope boundaries for the building, installation, commissioning, biofilter start-up, training and spares. Treatment sizing follows from feed load and temperature; without those figures every supplier quotes a different system.
- Sizing basis:
- Peak feed load and design temperature
- Most common omission:
- Redundancy and failure tolerance
- Supplier identities:
- Confidential until you approve
- Project focus:
- USD 250,000+ commercial projects
Requirements this RFQ must contain
Species, harvest size and market form
Sets density limits, temperature band, water-quality tolerance and handling requirements.
Annual production and peak standing biomass
Peak biomass is the design case for oxygen, biofiltration, degassing and pumping.
Production and harvest schedule
Batch versus continuous production changes peak load and how many independent modules you need.
Peak daily feed load
The single most important RAS number: it determines TAN production, oxygen demand, solids load and CO2 stripping duty.
Design temperature
Temperature sets growth, biofilter performance, oxygen solubility and heating or chilling load.
Make-up water volume and analysis
Available and affordable make-up water decides the recirculation rate and whether denitrification is needed.
Target water-quality envelope
Oxygen, TAN, nitrite, CO2, TSS, alkalinity and pH limits must come from you, or each supplier uses their own and the quotes diverge.
Redundancy and failure tolerance
Which single failures the system must survive, and for how long, decides backup power, emergency oxygen, spare pumps and duplicated loops.
Effluent, solids and sludge handling
Discharge limits and sludge disposal routes can add a full treatment stage that is otherwise excluded from quotations.
Energy price and grid reliability
RAS operating cost is dominated by energy; the tariff and outage profile change the economically correct design.
Building, site and civil interface
Insulation, floor drainage, ceiling height, crane access and utility connections decide what belongs in the supplier's scope.
Scope boundaries and support
Installation supervision, commissioning, biofilter maturation, first stocking support, operator training, spares and remote monitoring.
Scope the quotation must cover
- Culture tanks and hydraulics
- Mechanical filtration and solids removal
- Biofiltration and, where required, denitrification
- Degassing and CO2 stripping
- Oxygenation and emergency oxygen
- Disinfection (UV or ozone) and pumping
- Heating, chilling and heat recovery
- Monitoring, control system, alarms and backup power
- Effluent, sludge handling and discharge compliance

Frequently asked questions
Short answer
What is the fastest way to get quotes for RAS RFQ?
Submit one structured request for RAS RFQ. FishMatch Group translates it into a technical RFQ, runs a confidential sourcing round with project-matched international suppliers, and returns comparable quotations. No fee is charged to the buyer, and your identity and project details stay private until you choose to proceed.
- How it works:
- One structured request, human-reviewed before any supplier outreach
- Typical turnaround:
- Depends on scope and site data; no turnaround is guaranteed
- Confidentiality:
- Supplier names are never exposed during evaluation
- Cost to buyers:
- No fee charged to the buyer

FishMatch Group translates it into a technical RFQ, runs a confidential sourcing round with project-matched international suppliers, and returns comparable quotations. No fee is charged to the buyer, and your identity and project details stay private until you choose to proceed.
How does FishMatch Group source suppliers for this requirement?
You submit one structured request. We translate it into a technical RFQ, run it against qualified manufacturers and integrators in the relevant categories, and return normalised quotations you can compare side by side on scope, lead time and total cost of ownership.
Do buyers see supplier names during the sourcing process?
No. Supplier identities stay confidential during discovery and evaluation. You receive anonymised, comparable technical and commercial packages, and introductions happen only after both sides are qualified and agree to proceed.
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.
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.
