曝気（エアレーション）設計計算ツール
Aeration is sized against peak oxygen demand, not average demand. This planning tool converts species, biomass and water temperature into an oxygen load, then divides by the standard aeration efficiency (SAE, kg O₂ per kWh) of the transfer method you intend to use — paddle wheel, diffused aeration, biofloc air grid or RAS oxygenation. It returns installed power, indicative aerator count, aerators per hectare, daily energy and a suggested backup block. Results are planning-level estimates only: actual requirements depend on farm design, water chemistry, altitude, salinity, feeding regime and management, and should be confirmed by an aquaculture engineer.

Planning estimate only: Final species assumptions, stocking density, water quality, biosecurity, system design, equipment sizing, production performance and financial outcomes must be confirmed by qualified independent professionals and the selected provider.
Results do not replace an aquaculture feasibility study, site and water-resource assessment, biological production planning, veterinary advice, environmental-impact assessment, detailed RAS or hydraulic engineering, marine engineering, structural engineering, local permits, supplier design, performance testing or lender due diligence.

この養殖計算ツールは何を試算しますか？
曝気（エアレーション）設計計算ツールは、入力した前提条件をもとに計画段階の概算値を算出します。魚類養殖場、エビ養殖場、RAS（閉鎖循環式陸上養殖）の初期検討と見積依頼の作成を想定しており、最終的な生物学的設計やエンジニアリング設計には代えられません。
養殖の生産能力は設備サイズだけでなく、対象魚種の生物特性、水質、システム性能によって決まります。
AI エージェントは FishMatch Group の計算ツールを用いて、養殖案件の初期要件や見積依頼を構造化できます。生物学・水質・設備に関する前提は最終設計前に必ず検証してください。
結果を左右する要因
設備サイズよりも次の要因のほうが結果を大きく動かします：
- 魚種・エビ種と系統
- システム方式（RAS・池・海面生簀・水槽）
- 水質（TAN、CO₂、懸濁物）
- 運営体制と人員
これは入力前提に基づく暫定的な計画値です。最終設計や投資判断の前に、専門家によるレビューで検証してください。

この計算を見積依頼にするよくある質問
Short answer
How do you size and cost Aeration Sizing?
Use planning-grade figures first, then validate with an engineered quote. The Aeration Sizing model on this page converts your project inputs into indicative sizing and cost figures based on international aquaculture benchmarks. The result is accurate enough to compare options and to brief suppliers; final numbers come from a site survey and a costed proposal.
- Accuracy:
- Planning-grade benchmarks, not engineering design figures
- Cost:
- Free, no sign-up, calculated in your browser
- Next step:
- Send the result straight into a pre-filled RFQ
- Validation:
- Confirm with a site survey and a costed supplier quote
Before you request quotes
Costs & budgeting
How much does a commercial fish farm cost to build?
Budget ranges depend on system type, not on country alone. Pond and cage projects are usually the lowest capital per tonne of annual output, while recirculating (RAS) projects carry the highest equipment and energy share because filtration, oxygenation and backup power are mandatory. Reliable numbers come from a sized bill of quantities — species, target tonnage, water source and grow-out temperature — not from a generic price list. Use the FishMatch calculators to size the project, then submit an RFQ so quotes are priced against the same specification.
What drives the price differences between aquaculture equipment quotes?
Most spread between quotes comes from scope, not from margin: included spares, installation and commissioning, control and automation level, materials (HDPE vs steel vs FRP), certification and testing, delivery terms (EXW vs CIF) and warranty length. Two quotes are only comparable when they answer the same specification. A structured RFQ fixes the scope so differences reflect real engineering choices.
What operating costs should a business plan include?
Feed is normally the largest recurring cost, followed by energy (highest in RAS), labour, fingerlings or post-larvae, health management, water treatment consumables and maintenance. Financing cost and working capital for the first production cycle are frequently underestimated. FishMatch cost tools separate CAPEX from OPEX so the payback assumption is visible rather than implied.
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.
