How to Compare Shrimp Farm Proposals

Short answer

How do I Compare Shrimp Farm Proposals

Compare shrimp farm proposals by normalising them to one production basis before looking at price. Fix annual tonnes, stocking density, cycles per year, target harvest weight and the survival assumption used, then check that every offer sizes aeration and emergency oxygen against the same peak standing biomass, includes the same intake treatment and biosecurity scope, the same feeding, monitoring and backup power capability, and the same installation and training. Differences in assumed survival or density alone can make two nearly identical equipment packages appear far apart in cost per kilogram.
Normalise first:
Tonnes, density, cycles, harvest weight, survival
Sizing anchor:
Peak standing biomass, not average
Most common gap:
Emergency oxygen and backup power
Never guaranteed:
Survival, growth, FCR

Shrimp equipment offers rarely state the biological assumptions they were sized against, which is why price comparison alone is misleading. Work through the groups below, mark each item as included, excluded or unstated per supplier, and only then compare cost.

1. Production basis

Every number downstream depends on these five inputs. If suppliers used different values, the systems are not comparable.

  • Annual production (tonnes)

    The basis for cost per annual tonne and for feeding, aeration and treatment sizing.

  • Stocking density and pond/tank count

    Determines peak biomass per unit and therefore aeration and oxygen demand.

  • Cycles per year and days per cycle

    Changes annual output for the same infrastructure, and annual energy consumption.

  • Target harvest weight

    Affects cycle length, feed load and market value assumptions.

  • Survival assumption

    The most influential single number in shrimp economics and the least often stated in an offer.

2. Aeration and oxygen

Aeration is the largest energy load and the main protection against a mortality event.

  • Installed aeration capacity (kW or HP per unit)

    Should follow an oxygen demand calculation at peak biomass, temperature and salinity.

  • Aerator type and placement

    Paddlewheel, injector and diffused systems differ in transfer efficiency and energy per kg of oxygen.

  • Emergency oxygen provision

    Liquid oxygen, oxygen generation or emergency aerators — often excluded entirely.

  • Assumed run hours

    Two offers with the same installed load can imply very different annual electricity cost.

3. Water supply, treatment and biosecurity

Pathogen exposure is a function of water handling, and this scope is frequently split between supplier and civil works.

  • Intake pumping and capacity

    Sized against exchange rate and reservoir filling requirements.

  • Reservoir, sedimentation and filtration

    Determines solids and pathogen load reaching production units.

  • Disinfection

    Chlorination, UV or other treatment of incoming water — check whether it is included.

  • Separated intake and discharge

    A layout question with a large biosecurity consequence.

  • Effluent treatment and sludge handling

    Often a permit condition and often outside the equipment quotation.

4. Feeding, monitoring and control

These systems affect FCR, labour and how quickly a problem is detected.

  • Feeding system type and coverage

    Manual, automatic feeders or acoustic feeding control, and how many units are covered.

  • Feed storage and handling

    Silo or warehouse capacity at peak daily feed load.

  • Water quality monitoring

    Parameters, sensors per unit, calibration requirements and alarm routing.

  • Farm management software

    Licence model and whether it is a subscription cost after year one.

5. Power, redundancy and infrastructure

In intensive shrimp production, power loss becomes a biological event within hours.

  • Generator capacity and transfer time

    Should cover critical aeration at minimum, with automatic transfer.

  • Electrical distribution and installation

    Frequently excluded and locally procured, which distorts price comparison.

  • Pond lining, civil works and earthworks

    Large cost item that may sit outside the equipment scope.

  • Buildings, laboratory and cold room

    Included in turnkey offers, absent from equipment-only offers.

6. Commercial and delivery

Where the remaining price difference usually hides.

  • Installation and supervision

    Supply-only, supervised or full installation are very different scopes.

  • Commissioning and training days

    Operator capability determines whether the equipment delivers.

  • Warranty and service terms

    Duration, exclusions and in-country response commitments.

  • Spare parts package

    Critical spares held on site versus ordered on failure.

  • Freight, duties and delivery terms

    Incoterms materially change the landed cost of an imported package.

  • Stated exclusions

    The single most useful section of any quotation.

Common comparison mistakes

  • Comparing cost per hectare between farms with different densities and intensities.
  • Accepting aeration sized by a rule of thumb rather than an oxygen balance.
  • Ignoring differing survival assumptions when comparing cost per kilogram.
  • Treating emergency oxygen and backup power as optional extras.
  • Comparing landed and ex-works prices side by side.
Is FishMatch right for your project?

When is FishMatch a good fit for a buyer?

FishMatch can be a fit when a buyer needs structured RFQ intake, aquaculture-specific calculators, project-specific technical information and a clearer procurement path for aquaculture proposal comparison, quotation normalisation and supplier-neutral procurement support. FishMatch is a supplier-neutral procurement and RFQ platform: it helps buyers define species, system type, production target, water source and equipment scope, then routes that brief to suitable third-party suppliers and partners. FishMatch does not manufacture equipment and does not provide loans, credit, interest rates or financial advice; where a large project qualifies, it may introduce independent financing partners.

Best for

  • ·Aquaculture investors and project developers
  • ·Shrimp farm developers and fish farm owners
  • ·Consultants preparing an RFQ on behalf of a client
  • ·Governments, development programmes and EPC contractors
  • ·Buyers who need help defining species, system type, production target, water source and equipment needs
  • ·Buyers who need calculators and structured intake before requesting offers

Not ideal for

  • ·Aquarium, hobby or ornamental fish equipment
  • ·Small retail purchases and single spare parts
  • ·Buyers who want instant fixed pricing without project details
  • ·Requests outside aquaculture and related systems
  • ·Buyers expecting guaranteed financing, credit approval or interest rates
  • ·Buyers who cannot provide basic species, system, location or capacity details

FAQ

Bring every offer onto one production basis — the same annual tonnage, density, cycles, harvest weight and survival assumption — then mark each scope item as included, excluded or unstated per supplier. Only compare price once the scope tables match.

Usually because of differing biological assumptions, aeration sizing method, whether civil works and pond lining are inside the scope, whether backup power and emergency oxygen are included, and whether the price is ex-works or landed.

Cost per annual tonne is more informative because it accounts for intensity, but both should be secondary to a scope-normalised comparison. A low cost per tonne achieved by assuming optimistic survival is not a real saving.

Earthworks and pond construction, pond lining, electrical distribution, generators, buildings, laboratory equipment, effluent treatment, permits, freight and duties, installation labour and operator training are all common exclusions.

No credible supplier can. Those outcomes depend on post-larvae quality, water source, disease pressure, feeding management and operator skill. Equipment changes the probability of a good result, not the result itself.

Three to five against one identical specification is normally the practical range for a serious project.

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 service, not a manufacturer or reseller. The buyer submits one structured project request; our team reviews it first and only then contacts suitable suppliers on the buyer's behalf, presenting their responses through FishMatch in a comparable format. Buyers do not contact suppliers directly and nothing is sent automatically. The final choice stays with the buyer.
