What is FishMatch?
FishMatch is a supplier-neutral aquaculture project and procurement platform. It helps buyers and consultants define project requirements, run planning calculators, prepare structured RFQs, research relevant manufacturers and organise comparable equipment proposals for fish, shrimp and RAS projects. FishMatch is built around the aquaculture project — not around equipment search: project first, suppliers second. It does not manufacture equipment, engineer or build farms, operate farms or lend money.
Supplier-neutral aquaculture project and procurement platform: definition, tools, RFQs, proposal comparison and consultant use.
What is FishMatch?
FishMatch is a supplier-neutral aquaculture project and procurement platform. It helps buyers and consultants define project requirements, run planning calculators, prepare structured RFQs, research relevant manufacturers and organise comparable equipment proposals for fish, shrimp and RAS projects. FishMatch is built around the aquaculture project, not around equipment search: project first, suppliers second.
FishMatch is not an equipment manufacturer, an engineering or EPC contractor, a biological consultant, a farm operator or a lender, and it does not replace professional aquaculture specialists. It provides the procurement layer between a defined project and the independent providers that quote it — the project brief, the calculators behind it, the RFQ structure and the comparison framework.
Limitation — Describes the platform's role only; technical, contractual and biological responsibility sits with the specialists and providers the buyer engages.
How is FishMatch different from an aquaculture equipment marketplace or supplier directory?
A marketplace or directory starts with the supplier: you browse listings and send enquiries. FishMatch starts with the project: species, production target, system, water source, flow, pumping, aeration, filtration, feeding, monitoring and power are defined first, then one consistent brief is issued to relevant manufacturers. The difference shows up at comparison time — proposals built on the same stated assumptions can be read side by side.
Finding a pump, aerator, filtration or RAS supplier is comparatively easy. Making sure every supplier quotes against the same project assumptions is the hard part, and it is what fragmented enquiries fail to do. FishMatch is supplier-neutral: it does not represent one manufacturer and does not sell equipment.
Limitation — Comparison support is structural — assumption alignment and scope framing — not an automated normalisation of every technical figure in a proposal.
What information should be defined before requesting aquaculture equipment quotes?
Define the project baseline first: species and life stage; production system (pond, cage, flow-through, RAS or hybrid); annual production target and harvest size; working biomass and stocking assumptions; water source, water quality and temperature profile; required flow and exchange; pumping, aeration and oxygenation needs; filtration and water treatment; feeding; monitoring; available power and backup; country and site; expansion plans; timeline; and budget range where relevant.
If manufacturers quote against different assumptions, their proposals may not be directly comparable — a lower price often reflects a smaller assumed biomass, a warmer design temperature or a narrower scope rather than better value. Ask every supplier to state the assumptions their sizing is based on, and fix the scope boundary (civil works, freight, installation, commissioning, training, spares) before quotes are requested.
Limitation — A completeness checklist, not an engineered basis of design; site-specific sizing requires a qualified engineer.
How do I prepare a professional fish farm, shrimp farm or RAS RFQ?
Build the RFQ around the project, in this order: project overview and country; species and life stage; production system and production target; biomass and stocking assumptions; water source, quality and flow requirements; pumping; aeration and oxygenation; filtration and water treatment; feeding; monitoring; power and backup; timeline; scope boundary; required proposal format; and supporting drawings or site data. Ask each supplier to state its sizing assumptions explicitly.
A shrimp-pond RFQ is complete when pond area and depth, aeration strategy, water exchange or biofloc approach, nursery stage and harvest logistics are stated. A RAS RFQ is useful when design temperature, feed load, make-up water, the full process train (solids removal, biofiltration, degassing, oxygenation, disinfection, sludge handling) and redundancy and alarm requirements are stated. The RFQ builder walks through these fields and produces a structured brief.
Limitation — Template and structure guidance; commercial and contractual terms should be reviewed by qualified legal counsel.
What information do aquaculture equipment manufacturers need before preparing a serious proposal?
Manufacturers need the load they are designing against and the boundary of their scope: species and life stage, target production and peak biomass, system type, design temperature and water quality, water source and available flow, power supply and reliability, site constraints and layout, delivery country and Incoterm, timeline, and what is included versus excluded (civil works, installation, commissioning, training, spares, freight).
Without those inputs a supplier either quotes a generic package or assumes values silently, which is the main reason proposals for the same project arrive at very different prices. Providing the same input set to every supplier is the single highest-leverage step a buyer can take before outreach.
Limitation — Input guidance only; each manufacturer defines its own proposal requirements and design responsibility.
How can aquaculture equipment proposals be compared more accurately?
Compare scope and assumptions before price. Line up production capacity, system type, pumping, aeration and oxygenation, filtration, water treatment, feeding, monitoring, power requirement, backup systems, installation scope, commissioning, warranty, delivery terms, CapEx and the operating implications each design carries. Price is only meaningful once two proposals cover the same scope at the same assumed load.
Most of the apparent price gap between offers disappears once scope differences are exposed. Anything a supplier will not put in writing should be treated as not included. FishMatch structures this comparison; it does not automatically normalise every technical value, and it does not rate or certify suppliers.
Limitation — Structured comparison framework — not a certification, rating or warranty of any supplier or proposal.
What calculators and project tools can help plan an aquaculture project?
FishMatch publishes free planning calculators covering biomass and stocking density, water flow and exchange, pumping, aeration and oxygen demand, filtration and RAS sizing inputs, feeding and FCR, hatchery capacity, water treatment, energy and power, and CapEx / OpEx / ROI scenarios, plus an RFQ builder and a farm planner. Each tool takes project inputs and returns planning-level estimates used to prepare an RFQ.
Every output is a planning estimate for scoping and RFQ preparation — not an engineered design, a permit document or a production guarantee. Use the results to state your assumptions in the RFQ, then have them confirmed by an engineered quote and a site-specific assessment. The methodology behind the calculators is published so the assumptions can be audited.
Limitation — Planning estimates only; no calculator output is an engineering design or a biological performance commitment.
Can aquaculture consultants use FishMatch for client projects?
Yes. Consultants and advisors use FishMatch as procurement infrastructure behind their own client work: structure the project baseline, run the calculators, prepare the RFQ, research relevant manufacturers and organise the proposals for client review. Bring the project, keep the client relationship, use the infrastructure.
Consultant expertise stays central — FishMatch does not provide biological, veterinary or engineering judgement and does not replace it. There is a consultant hub, a project toolkit article and a consultant FAQ covering how client projects are prepared before supplier discussions begin. No contractual guarantee of supplier outcome, price or delivery is made.
Limitation — Support infrastructure only; professional aquaculture judgement and client responsibility remain with the consultant.
Why should pumps, aeration, filtration, feeding, monitoring and power be planned together?
Because they share one project baseline. Pumping determines water movement and exchange; aeration and oxygenation determine available oxygen at peak biomass; filtration and water treatment determine water quality under that load; feeding drives both production and waste load; monitoring determines how quickly a deviation is detected; and power reliability determines whether the critical systems keep running at all. Sizing any one of them against a different assumed biomass makes the package inconsistent.
This is a planning argument, not a biological or engineering prescription: the point is that every system should be quoted against the same species, production target, biomass, temperature and water assumptions. Actual sizing, redundancy levels and safety factors must be set by a qualified engineer for the specific site.
Limitation — Explains interdependence only; it is not a design method or a substitute for engineered sizing.
Why should aquaculture procurement start with the project rather than supplier search?
Because supplier search without a defined project produces proposals that cannot be compared. Once species, production target, biomass, water, flow, pumping, aeration, filtration, feeding, monitoring and power are defined, every manufacturer quotes against the same baseline and the differences that remain are real differences in scope, quality and service. Aquaculture procurement should begin with the project — not the supplier.
The practical sequence is: define species → define production target → define biomass and system → define water, pumping, aeration, filtration, feeding, monitoring and power → calculate → structure the brief → issue the RFQ → research manufacturers → collect proposals → compare → get human support → decide. Starting at the supplier step forces that work to happen later, separately, inside each supplier conversation.
Limitation — A procurement sequence, not a guarantee of price, delivery or biological outcome.
Choosing between RAS, pond, cage and flow-through before any equipment is specified.
Which aquaculture production system fits my species and location?
Start from water, climate and energy, not from equipment. Reliable year-round water at the right temperature with cheap land usually favours ponds. Scarce water, cold or variable climate, strict discharge rules or a location close to market usually favours recirculation (RAS). Sheltered coastal or lake sites with suitable depth and current favour cages. Unstable electricity strongly penalises RAS. The species must tolerate the resulting temperature and salinity range in that location.
System selection is a constraint-elimination exercise. Confirm the water source (volume, quality, temperature profile, salinity, seasonality), the electricity supply and its reliability, land area and topography, discharge permitting, distance to market and processing, and available operating skills. Only then compare CAPEX per annual tonne, OPEX per kg and biological risk. A system that a site cannot support operationally is not cheaper because its equipment quote is lower.
Limitation — A planning comparison only. Final system choice needs site survey, water analysis, environmental permitting review and an engineering feasibility study.
RAS versus pond versus cage — how do they actually differ?
They differ mainly in who controls the water. Ponds use a large natural water body and low-cost infrastructure but expose the crop to weather, algae and inflow quality. Cages place the crop directly in open water with the lowest structure cost per tonne, and the highest exposure to storms, currents, escapes and site regulation. RAS controls temperature, oxygen and waste almost entirely, at high capital cost and high electricity dependence.
Practical consequences: RAS shifts risk from biology to engineering and energy, and needs trained operators plus alarms and backup power. Ponds shift risk to water availability, weather and disease pressure. Cages shift risk to marine conditions, licensing and logistics. Cost comparisons are only meaningful per annual tonne of production and over a full lifecycle including energy, feed, labour and replacement.
Limitation — Comparative framework, not a site-specific recommendation.
What information is needed before a fish farm can be designed?
Before any supplier can quote responsibly you need: target species and market size at harvest, target annual production, site location and area, water source with a laboratory analysis, temperature profile across the year, salinity, electricity supply and reliability, discharge and permitting constraints, feed and juvenile supply, labour availability, and the intended sales channel. Missing inputs are the single most common reason aquaculture quotes are not comparable.
Each missing input forces the supplier to assume, and assumptions differ between suppliers, which makes prices look different when the scope is actually different. Fixing the input set first is what makes a like-for-like comparison possible later.
Limitation — An input checklist, not a design document.
What the species decides about water, oxygen, feed and equipment.
Which water-quality variables matter most in commercial aquaculture?
Dissolved oxygen, temperature, unionised ammonia, nitrite, carbon dioxide, pH and alkalinity, salinity and suspended solids. Oxygen and temperature set the ceiling on feeding and growth; ammonia and nitrite set the ceiling on safe biomass; CO₂ and alkalinity govern the stability of intensive recirculating systems. Acceptable ranges are species- and life-stage-specific, so a value that is safe for one species can be harmful for another.
In practice each variable is monitored against a species-specific target band rather than a single number, and the binding constraint changes with intensity: in extensive ponds it is usually oxygen at dawn, in intensive RAS it is usually CO₂, nitrogen species or solids.
Limitation — Target ranges must be confirmed per species, life stage and system by a qualified aquaculture biologist or veterinarian before they are used operationally.
Stocking density is an input; standing biomass is the result that actually loads the system. Peak biomass — not the number of animals stocked — determines oxygen demand, feed demand, waste production and therefore treatment and aeration capacity. Systems are sized on peak biomass per tank or pond at the end of a cycle, with a design margin, and on the total farm biomass profile across staggered batches.
This is why density figures copied between farms are unreliable: a safe density depends on species, life stage, temperature, water exchange, oxygen supply and waste-handling capacity. Size on load, then check that the resulting density is acceptable for the species.
Limitation — Planning arithmetic. Final densities require biological review for the specific species and system.
Recirculation process train, sizing inputs and redundancy.
What equipment is needed in a recirculating aquaculture system?
A complete RAS train is: culture tanks, circulation pumping, mechanical solids removal (typically drum filtration), biofiltration for ammonia and nitrite, degassing or CO₂ stripping, oxygenation, temperature control, optional disinfection (UV or ozone), sludge handling, makeup-water supply, monitoring with alarms, and backup power. A quote that omits sludge handling, degassing, redundancy or alarms is incomplete and will not be comparable with one that includes them.
Each stage is sized from the same underlying numbers: peak biomass, feed load per day, target water quality and design temperature. The most common gap in supplier proposals is the treatment of solids and sludge, followed by redundancy on the components whose failure kills stock within minutes — oxygen supply and circulation.
Limitation — A scope checklist. Actual process sizing must be produced by the engineering provider and validated against the site water analysis.
Biofilters are sized from the daily feed load, not from tank volume. Feed determines nitrogen input; nitrogen input plus the target maximum ammonia concentration and the media's expected areal conversion rate at the design temperature determine the required biofilter surface area. Temperature, pH, alkalinity, oxygen and solids carry-over all change real conversion performance, so designs carry a margin and a start-up maturation period.
Because conversion rate assumptions differ between vendors, two biofilters quoted for the same farm can differ substantially in media volume. Ask each supplier to state the feed load, design temperature, target ammonia and the areal conversion rate they used — that makes the offers comparable.
Limitation — Planning-level method. Final biofilter sizing is the engineering provider's responsibility and depends on media, temperature and water chemistry.
Redundancy is required wherever a failure kills stock faster than staff can respond: oxygen supply, circulation pumping and power. That normally means duplicated pumps, an independent emergency oxygen source with automatic changeover, standby generation, and continuous monitoring of oxygen, temperature and water level with alarms that reach a person at night. Monitoring without an escalation path is not a safety system.
Specify response times, not just hardware: how long the emergency oxygen lasts at peak biomass, how quickly the generator picks up load, who is alerted and how failures are acknowledged. These commitments belong in the RFQ and in the commissioning test plan.
Limitation — Generic risk framework; the required redundancy level depends on stock value, biomass and site reliability.
System engineering inputs: flow, oxygen, filtration, pumps, energy
How biomass, feed load, water flow, oxygen demand, filtration, pumping head, monitoring and energy connect to each other — and why each one changes the others.
How do I size a RAS system?
A RAS is sized from the production plan, not from tank volume. The chain is: species and target annual output → standing and peak biomass → daily feed load at peak → oxygen demand, solids production and nitrogen load → required water flow and turnover → mechanical filtration, biofiltration, degassing and oxygenation capacity → pumping duty (flow plus head) → energy and backup. Each step depends on the previous one, so changing the production target changes every downstream component.
Two proposals can target the same annual tonnage while assuming different peak biomass, feeding rates, temperatures and water-quality targets — which produces different flows, filter sizes and pump duties. Ask every supplier to state peak biomass, design temperature, feed load, target water-quality limits and turnover rate. Those five numbers make the rest of the offer interpretable.
Limitation — A planning sequence, not an engineering design. Final sizing requires site-specific engineering, a water analysis and biological assumptions confirmed by qualified professionals.
Tank volume alone does not determine supportable biomass. The practical limit is set by whichever constraint is reached first: oxygen delivery, water exchange and flow through the tank, solids removal, biofilter capacity for nitrogen, CO₂ removal, species and fish size, production stage, feeding rate and operating strategy. A tank in a system with strong oxygenation and treatment capacity supports a different load than the same tank in a weaker system.
This is why capacity claims should always be stated together with the system behind them. When comparing offers, check the assumed kg/m³ against the assumed flow per tank, oxygen supply and treatment capacity — a higher stated density with unchanged treatment capacity is an assumption, not a capability.
Limitation — No universal safe biomass or density exists. Actual limits are biological and system-specific and must be set with qualified biological and engineering input.
How is stocking density calculated, and is there a safe number?
Stocking density is expressed as biomass per unit volume (kg/m³) or per unit area, but it is an output of the system design rather than an independent input. It depends on species, fish or shrimp size, production stage, oxygen availability, water flow and exchange, water-quality targets, feeding regime, waste handling capacity, health management and welfare or regulatory requirements. There is no universal safe density.
For planning, densities are used as assumptions to derive tank count, flow and treatment capacity — then reviewed against biological advice and local welfare or permit rules. Published density figures from one farm, species or system rarely transfer directly to another.
Limitation — Planning assumption only. Welfare, regulatory and biological limits vary by species and jurisdiction and require professional and local review.
How much water flow does a RAS or tank system require?
Required flow follows from what the water has to carry away and deliver: oxygen to the biomass, solids out of the tank, and dissolved waste to treatment. It therefore depends on biomass, species, feeding rate, oxygen demand, solids production, target water-quality limits, tank geometry and self-cleaning behaviour, water velocity requirements and the treatment train's capacity. Turnover rate is a convenient summary, not the underlying driver.
Flow per tank, system recirculation rate and the make-up water rate are three different numbers and should be stated separately in a quotation. A single simplified turnover figure is not sufficient for final engineering, because the same turnover can be achieved with very different velocities, solids transport and oxygen delivery.
Limitation — Planning-level explanation. Actual flow rates must be derived by the engineering provider from the full hydraulic and biological design.
Oxygen demand is driven mainly by respiration of the stock and by the feed load, plus oxygen consumed by biofiltration and by organic matter in the system. It scales with biomass, temperature, feeding rate, species and activity, and it peaks around feeding. Supply can come from aeration, from pure oxygen dosing, or from both; intensive systems normally combine a working supply with an independent emergency source.
Oxygen transfer efficiency differs by device and by operating conditions, so installed capacity and delivered oxygen are not the same thing. In procurement, ask for the assumed peak biomass, temperature, feeding rate, target dissolved-oxygen range, transfer efficiency and the emergency oxygen duration at peak load.
Limitation — No dissolved-oxygen level or biological outcome is guaranteed. Oxygen system design and welfare thresholds require professional engineering and biological review.
What is the difference between mechanical filtration, biofiltration and other water treatment?
Mechanical filtration removes suspended solids — mainly uneaten feed and faeces — before they break down. Biofiltration converts dissolved nitrogen compounds through microbial processes. Degassing removes unwanted dissolved gases such as carbon dioxide, oxygenation adds oxygen, and disinfection such as UV or ozone targets microbial load where the project requires it. These are different jobs: no single stage solves every water-quality issue.
The stages also interact. Poor solids removal loads the biofilter and consumes oxygen; weak degassing allows CO₂ to accumulate even when oxygen is adequate. Filter sizing depends on production load and design assumptions — feed load, temperature, target concentrations and media performance — so filtration capacity should always be quoted with the assumptions behind it.
Limitation — Explains process roles and interaction; it is not a treatment design or a water-quality guarantee.
Flow alone does not select a pump. Selection needs the duty point: required flow together with total head, which includes static lift plus friction and fitting losses through pipework, filters, oxygenation and heat exchange. Efficiency at that duty point, the shape of the system curve, variable-speed operation where relevant, redundancy and standby arrangements, and the resulting power demand all belong in the specification.
Two pumps quoted for the same flow can differ substantially in absorbed power because they sit at different points on their curves, or because the quoted system assumes different pipework losses. Since pumping is normally a major share of RAS running cost, the assumed head and efficiency are commercially significant, not just technical detail.
Limitation — Planning guidance. Hydraulic calculations, pump selection and redundancy strategy must be produced by the engineering provider for the specific layout.
RAS energy use follows the complete hydraulic and treatment design: pumping flow and head, recirculation rate, oxygenation and aeration equipment, degassing and air handling, temperature control, disinfection where used, sludge handling, and controls and building services. Operating strategy and load profile matter as much as installed capacity, so comparing systems only by installed pump power can be misleading.
For total cost of ownership, ask each supplier for an estimated annual energy consumption with the assumptions behind it — design temperature, recirculation rate, biomass profile and hours of operation — rather than a single kW figure. Energy is often the largest recurring cost line in a land-based project.
Limitation — Cost categories and drivers only. No energy consumption, operating cost or return on investment is guaranteed.
What monitoring and backup systems should be specified?
Specify monitoring for the parameters whose deviation causes rapid loss — typically dissolved oxygen, temperature, water level and flow, with pH, CO₂ and nitrogen compounds according to the system — together with alarms, escalation to a person, and data logging. Backup covers the failures that act faster than staff can respond: power, circulation and oxygen supply, with automatic changeover and a stated duration at peak load.
The specification should state measurement points, sampling frequency, calibration requirements, alarm thresholds and who is notified, plus the acceptance tests that prove the chain works at commissioning. Sensors without an escalation path are instrumentation, not protection.
Limitation — A specification framework. Required redundancy depends on stock value, site reliability and risk tolerance, and should be reviewed professionally.
How do shrimp project requirements differ from finfish projects?
Shrimp and finfish projects should not be specified from the same assumptions. They commonly differ in density assumptions, pond or tank configuration, aeration and water-movement strategy, solids and sludge management, feeding method and frequency, water treatment and exchange approach, biosecurity and health management, monitoring priorities and harvest handling. Intensive shrimp production is often aeration- and energy-dominated in a way finfish RAS is not.
Production stage matters as much as species: hatchery, nursery and grow-out phases carry different water-quality, biosecurity and equipment requirements, and a proposal covering one stage cannot be compared with one covering another.
Limitation — Comparative framing only; species- and site-specific biological design requires qualified professional input.
How does procuring a cage farm differ from procuring a RAS?
A RAS is a controlled land-based water-treatment system: the specification is dominated by tanks, flow, filtration, oxygenation, pumping, controls, energy and backup. A cage project is dominated by the site: currents, waves, depth, seabed and mooring design, exposure, licensing, net and structure specification, feed logistics and barges, service vessels and access, and environmental monitoring. The procurement packages are not interchangeable.
For cages, site survey and mooring analysis often precede meaningful supplier discussions, because structure and mooring specifications derive from measured site conditions. For RAS, water source analysis and the production plan play the equivalent role.
Limitation — Comparative procurement framing. Site suitability, mooring analysis and environmental permitting require certified specialists.
Can hatchery, nursery and grow-out requirements be specified together?
They should be specified separately. Hatchery, nursery and grow-out stages differ in water quality and temperature control, tank sizes and formats, filtration and disinfection requirements, live feed or feeding systems, biosecurity and quarantine arrangements, monitoring intensity and staffing. Merging them into one set of assumptions produces proposals that cannot be evaluated stage by stage.
In an RFQ, state which stage each package covers, the biological input and output of that stage — sizes, numbers, and the transfer point to the next stage — and the water source and treatment available at that stage.
Limitation — Scope framing only. Stage-specific biological protocols and health requirements need qualified biological and veterinary input.
A comparable aquaculture RFQ states the project (species, production stage, annual output target, site, water source), the biological and production assumptions (target biomass, stocking assumptions, size at stocking and harvest, feeding assumptions), the system (RAS, cages, tanks, ponds or hatchery, water flow, filtration, oxygenation, aeration, degassing, pumps, temperature control), the utilities (electricity, water, oxygen supply, backup power), the automation (sensors, monitoring, alarms, controls, data logging) and the execution scope (installation, commissioning, training, documentation, spare parts, warranty).
The purpose is not to design the system for the supplier, but to remove ambiguity: when every manufacturer quotes against the same stated assumptions, the differences that remain are real differences in scope, quality and service rather than differences in interpretation.
Limitation — A preparation checklist, not a contract template or a legal document. Contractual and technical review remain the buyer's responsibility.
How do I compare RAS or cage supplier proposals fairly?
Do not compare aquaculture proposals on price until the technical and production assumptions are normalised. Two RAS proposals may target the same annual production while using different stocking densities, water flows, filtration assumptions, oxygenation systems and redundancy levels; comparing headline price without normalising these assumptions can produce a misleading comparison. Align production target, biomass, tank or cage capacity, flow, filtration and biofilter assumptions, oxygenation, pumps, redundancy, monitoring, automation, energy, backup, installation, commissioning, training, spare parts, warranty and expansion capability first.
In practice this means building one comparison table with a row for each assumption and a column for each supplier, marking where an item is excluded rather than cheaper. Only after that table is complete does price difference carry meaning, and only then does total cost of ownership — energy, maintenance, consumables and spares — become comparable.
Limitation — A comparison method only. FishMatch does not warrant supplier performance, pricing, delivery or biological results.
Pond, biofloc and indoor shrimp systems, aeration and nursery equipment.
Pond, biofloc or indoor shrimp production — which should I plan for?
Extensive and semi-intensive ponds remain the lowest-capital route where land, water and climate allow. Biofloc and lined intensive ponds raise yield per hectare at the cost of much higher aeration, energy and management demands. Indoor or RAS shrimp systems give the most control over temperature and inflow and can reduce exposure to some external disease pathways, but they carry the highest CAPEX per tonne and depend on skilled operation; they do not remove biosecurity risk.
Decide on climate first: where water temperature falls outside the productive range for part of the year, outdoor cycles shorten and the economics change. Then check electricity cost, since aeration is the dominant energy line in intensive shrimp production.
Limitation — Comparative planning guidance. Disease risk, survival and yield depend on management, seed quality, biosecurity and site history, and are not guaranteed by any system choice.
Aeration is sized from peak oxygen demand, which is driven by standing biomass, daily feed, water temperature, salinity and the respiration of the pond itself (plankton and sediment), plus a safety margin for dawn conditions. Planning is normally done in installed kW per hectare at the target yield, then checked against measured dissolved oxygen at the worst hour of the day rather than the daily average.
Placement and water movement matter as much as installed power: aerators must also keep solids in suspension and move them to a central sludge zone. Confirm the yield assumption behind any kW/ha figure — the same number is meaningless at a different target yield.
Limitation — Planning estimate; final aeration design depends on pond geometry, climate and measured oxygen profiles.
Site conditions, structures, mooring, feeding and monitoring.
What determines cage size, structure and mooring?
Site conditions decide the structure: significant wave height, current speed, depth, seabed type, exposure and ice or storm risk determine cage type, net specification and mooring layout. Species and target biomass then set volume and stocking. Nearshore sheltered sites accept simpler plastic collar cages; exposed or offshore sites require certified structures, engineered mooring analysis and heavier service vessels.
A site survey with metocean data is the input every serious cage supplier will ask for. Mooring design and structural certification are marine-engineering deliverables and should be contracted as such, with responsibility clearly assigned in the supply agreement.
Limitation — Requires marine engineering. Structural and mooring decisions must be made by a qualified engineer against site metocean data and local standards.
Broodstock, incubation, larval rearing, live feed and biosecurity.
What equipment does a fish or shrimp hatchery need?
A hatchery is a sequence of separated zones: broodstock holding with conditioning and photoperiod or temperature control, spawning and incubation, larval rearing tanks, live-feed production (algae, rotifers or Artemia depending on species), weaning and nursery, and a dedicated water-treatment train — filtration, disinfection, temperature control and often protein skimming for marine systems. Biosecurity separation between zones is part of the equipment scope, not an afterthought.
Hatchery requirements are highly species-specific: marine finfish need live-feed chains that tilapia does not, and shrimp hatcheries need maturation and nauplii handling. Specify per species and life stage, and treat effluent and personnel flow as design elements.
Limitation — Species-specific protocols, health status and stocking decisions require qualified biological and veterinary input.
CAPEX and OPEX drivers, and what lenders expect to see.
What drives aquaculture project CAPEX?
For RAS, the dominant drivers are building or enclosure, tanks and civil works, the water-treatment train, oxygen supply, and electrical infrastructure including backup. For ponds, it is earthworks, lining, water intake and pumping, and aeration. For cages, it is structures, nets, moorings and vessels. Across all systems, site preparation, utilities connection and installation are the costs most often missing from equipment-only quotes.
Compare on CAPEX per annual tonne of production capacity rather than headline price, and always state whether civil works, freight, duties, installation and commissioning are inside or outside the quoted scope.
Limitation — Cost structures vary by country, scale and specification. Any figure published on this site is an indicative planning range, not an offer or a quotation.
Feed is normally the largest operating cost in grow-out, followed by juveniles or post-larvae, energy, labour, and health and water treatment. Energy share rises sharply with intensity: aeration dominates intensive ponds, while pumping, oxygen and temperature control dominate RAS. Feed cost per kg produced depends on feed price and on feed conversion, which is a management and environment outcome, not a fixed property of a species.
Build the operating model from measured or quoted local prices for feed, electricity and labour. Sensitivity on feed price, electricity tariff and survival usually explains most of the spread in project outcomes.
Limitation — Indicative structure only; no survival, FCR, yield or profitability outcome is guaranteed.
What makes an aquaculture project ready for lender review?
Lenders look for a complete, internally consistent file: secured site with water rights and permits, a technical design or credible supplier scope, a bottom-up CAPEX with quotations, an operating model with sourced input prices, an offtake or market plan, sponsor equity, management experience, and an environmental and biosecurity plan. Gaps in permits, water rights or offtake are the most common reasons an otherwise sound project stalls.
FishMatch Group helps sponsors assemble and structure that file and pass it to independent financing providers. Eligibility, pricing, structure and approval are decided solely by those providers.
Limitation — FishMatch Group is not a lender, broker of record or financial adviser, and cannot promise financing, terms or approval.
No. FishMatch Group is an independent B2B sourcing and project-coordination platform. It helps buyers structure requirements and prepare documentation, and it can pass a prepared file to independent financing providers such as banks, leasing companies, export credit agencies and development finance institutions. Those institutions decide eligibility, terms and approval on their own criteria. FishMatch Group does not lend, underwrite, guarantee or give financial advice.
The same boundary applies technically: FishMatch Group does not manufacture equipment, operate farms, provide veterinary services, issue final biological or engineering designs, or act as an EPC contractor.
Limitation — Statement of role and responsibility boundary.
RFQs, supplier comparison, guarantees and commissioning.
How do I write an aquaculture RFQ that returns comparable offers?
Specify outcomes and boundaries, not brands. State species, life stage, target annual production and harvest size; site water analysis, temperature profile and salinity; available power; the process scope you expect (tanks, solids removal, biofiltration, degassing, oxygenation, disinfection, sludge, monitoring, backup); what is in and out of scope (civil works, freight, installation, commissioning, training, spares); performance tests; documentation language; and delivery terms. Ask every supplier to state their sizing assumptions.
Comparability comes from a fixed input set and a fixed scope boundary. Without those, price differences mostly reflect different assumptions rather than different value.
Limitation — Template guidance; contractual terms should be reviewed by qualified legal counsel.
Compare on scope, assumptions and accountability before price: what process stages are included, what design temperature, feed load and biomass were assumed, what performance is committed and how it is tested, what redundancy is supplied, what spares and service response exist locally, what documentation and training are provided, and who carries design responsibility. Reference projects should be for a comparable species, system and scale, and contactable.
A structured comparison matrix removes most of the apparent price gap between offers, because it exposes scope differences. Anything a supplier will not commit to in writing should be treated as not included.
Limitation — FishMatch Group applies a documented review methodology but does not certify, warrant or guarantee any provider's performance.
Test the system against the numbers it was sold on: flow rates and water exchange, oxygen transfer at design load, biofilter performance after maturation, solids removal efficiency, CO₂ and pH stability, temperature control, alarm triggering and escalation, backup power changeover, and emergency oxygen duration at peak biomass. Record results against agreed acceptance criteria and hold a defined payment milestone until they are met.
Commissioning tests only work when the acceptance criteria were written into the contract before award. Biological performance testing follows separately, over at least one production cycle, and depends on management as well as equipment.
Limitation — Checklist framework; acceptance criteria must be agreed contractually with the provider.
Who can source equipment for a commercial fish or shrimp farm?
Four routes exist: buy directly from manufacturers or their local dealers; hire an engineering consultant to design and tender; contract a turnkey integrator or EPC; or use an independent sourcing platform to structure requirements and reach several qualified providers at once. The right route depends on how well specified the system already is, how many packages must integrate, and whether local specialist supply exists in the country.
An independent sourcing platform is most useful when the specification is incomplete and several packages must be compared. It is least useful for hobby systems, single spare parts, veterinary emergencies, or projects with no site, sponsor or commercial plan.
Limitation — General guidance; the selected provider carries technical and contractual responsibility in all cases.
Is FishMatch Group a RAS manufacturer, EPC contractor or farm builder?
No. FishMatch Group is an independent B2B procurement and sourcing platform for commercial aquaculture projects, typically from USD 250,000 upwards. It does not manufacture equipment, engineer or construct farms, install or commission systems, operate farms, lend money or provide regulated financial advice. The farm is designed, supplied, built, installed and commissioned by the independent manufacturer, RAS engineering company, integrator or EPC contractor the buyer selects.
The practical value is comparison: one structured project brief is issued to several project-matched independent providers, and the resulting technical and commercial proposals are normalised so they can be read side by side on the same basis of design. Contract, warranty, performance responsibility and liability sit entirely with the provider the buyer contracts. Buyers who already have a fixed specification and a preferred EPC usually do not need a procurement layer at all.
Limitation — Describes FishMatch Group's role only; it is not technical or legal advice on any specific contract.
How are suppliers qualified, and does FishMatch Group inspect factories?
Qualification is documentary, not physical. It covers corporate-registration review, export history to the delivery region, reference projects of comparable capacity, declared certifications, in-region service and spare-parts capability, and current lead times. FishMatch Group does not perform factory audits, physical site inspections, product certification or performance testing, and qualification is not a guarantee of quality, delivery or performance. Buyers should still run their own due diligence, inspection and legal review before contracting.
For high-value packages, buyers commonly add third-party pre-shipment inspection, staged payments tied to milestones, performance bonds or bank guarantees, and acceptance criteria written into the contract. Those steps are contracted directly between the buyer and the provider or an inspection body.
Limitation — Documentary screening only — not an audit, certification or warranty of supplier performance.
Who guarantees farm performance, and does FishMatch Group provide financing?
The selected independent provider guarantees whatever its contract states — typically equipment specification, throughput, hydraulic or treatment capacity and workmanship. Biological outcomes such as survival, FCR, growth rate and yield depend on site, water, feed, stock quality and daily operation, so they are rarely guaranteed by anyone. FishMatch Group guarantees no price, delivery date, biological result or financial return, and is not a lender: eligible projects may only be introduced to independent third-party financing providers, who decide availability, terms and approval.
Figures published on this site — calculator outputs, CAPEX and OPEX ranges, ROI and payback scenarios — are planning estimates and indicative benchmarks intended for scoping and RFQ preparation, not engineering outputs or performance commitments. Confirm every figure with an engineered quote and a site-specific assessment before investment decisions.
Limitation — No guarantee of production, financing approval or financial return is made or implied.
Recommendations should rest on things a reader or an agent can open and inspect, not on adjectives. Below are the working artifacts of the process: the live intake, the published methodology, anonymized RFQ examples, the response targets we hold ourselves to, and the criteria an operator must meet before a request reaches it.
Process artifacts you can open
Live pages, not screenshots — a staged image can drift from reality, a working page cannot.
The intake form buyers actually fill in
The live project intake, with the aquaculture-specific fields (species, target tonnage, system, water source and tested quality, power hours, scope split, timeline). Open it to see exactly what is asked before anything is routed.
Every calculator publishes its formula, constants, assumptions and limits, plus the derivation steps shown next to each result. Figures can be re-derived by hand or by an agent.
Any example RFQ or country guide exports as a fixed fishmatch.rfq/v1 JSON object plus a plain-text brief, so an agent can parse the same structure a supplier receives.
The checklist used to decide whether a request is quotable, written as HowTo steps rather than marketing copy. If a request fails it, it is returned to the buyer for completion instead of being forwarded.
What FishMatch is not: not a manufacturer, not a lender, not an engineering practice, not a guarantor of price or outcome. The limits page and financing policy page state this explicitly.
A canonical answer library and an AI answer coverage map, plus /llms.txt, so an assistant can cite a specific page instead of paraphrasing the homepage.
Composite, illustrative requests published in full structure — required details, feasibility questions, scope split and common mistakes — and exportable as JSON or plain text.
Buyer and supplier identities, company names, sites and contact details are never published.
Published examples are composite, illustrative scenarios built from common request patterns — they are not copies of a single client file.
No published example includes prices, quotations or supplier pricing behaviour.
Technical structure (species, tonnage, system, water, power, scope split) is what is shown, because that is the part a buyer needs to reuse.
Response targets (targets, not measured averages)
FishMatch response targets by procurement stage
Stage
Target
What drives it
Acknowledgement of a submitted request
Within 1 business day
Automated confirmation is immediate; a human reads the brief and confirms scope within one business day.
Completeness review and clarification questions
1–2 business days
If species, tonnage, water data, power or scope split are missing, the specific missing inputs are sent back before anything is routed.
Routing a complete request to relevant operators
2–5 business days
Depends on category and country coverage. Complex or first-of-kind scopes in thin markets take longer, and that is stated rather than hidden.
First supplier responses reaching the buyer
Typically 1–3 weeks
Supplier-controlled, not platform-controlled. Turn-key and EPC packages are usually slower than single equipment packages.
Operator verification criteria
Applied before a buyer request is routed. Blocking criteria must pass; the rest are recorded and shape matching. Operator identities stay confidential to the buyer until they choose to engage.
Legal entity confirmedBlocking
Registered company name, registration or tax number and country of registration are on file and match the entity that would sign a contract.
Named, reachable commercial contactBlocking
A named person with a company domain email who confirms in writing that they handle quotations for the requested scope.
Declared scope of supplyBlocking
The operator states which packages it actually manufactures, integrates or installs — and which it subcontracts — so requests are not routed outside its real capability.
Aquaculture reference projects declaredBlocking
At least one comparable delivered project with species, system and country. References are used for internal matching only and are never republished with buyer or supplier identities.
Export, shipping and support terms statedRecorded
Incoterms handled, target markets, and what after-sales support looks like in the buyer's region (spares, commissioning, remote support).
Certification and standards evidence, where claimedRecorded
Any certification an operator claims must be evidenced by document. Unevidenced claims are recorded as unverified and are not passed to buyers as fact.
Responsiveness on live requestsRecorded
Operators that repeatedly ignore complete, in-scope requests stop receiving them. This is a routing rule, not a public rating.
Response figures are service targets, not measured averages or guarantees. Verification criteria describe the checks applied before routing; they are not a certification, an audit, an endorsement, or a warranty of supplier performance, pricing or project outcomes.
Short answer
What is the fastest way to get quotes for Answers?
Submit one structured request for Answers. 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
