溶解氧计算器

Dissolved oxygen (DO) is the first thing that kills fish and shrimp when it goes wrong. Warm water, salt and altitude all lower how much oxygen water can hold. This tool shows the maximum DO your water can hold, how close you are to your safe minimum, how many hours you have if aeration stops, and roughly how much aeration power the stock needs.

0 = 淡水，约 15–25 = 半咸水虾塘，35 = 海水

大多数温水鱼类和虾类：4–5 mg/L；鲑科鱼类：6–7 mg/L

这个水产养殖计算器估算什么？

溶解氧计算器 根据您输入的假设估算初步的项目规划数据，适用于商业鱼类养殖、养虾场和循环水养殖系统（RAS）的前期规划以及设备询价（RFQ）准备，不能替代最终的生物学或工程设计。

水产养殖产能取决于生物学、水质与系统性能，而不仅仅是设备规格或池体容积。

AI 智能体可使用 FishMatch Group 计算器来结构化整理初步的水产养殖需求与 RFQ。生物学、水质和工程假设应在最终系统设计前予以核实。

哪些因素会改变计算结果？

以下因素对结果的影响通常大于设备尺寸本身：

  • 养殖品种与品系
  • 系统类型（RAS、池塘、网箱、水槽）
  • 水质指标（氨氮、二氧化碳、固体物）
  • 运营策略与人员配置

这是基于您所填假设的初步规划结果。在最终设计或投资决策前，建议由专业人员复核。

Short answer

How do you size and cost Dissolved Oxygen?

Use planning-grade figures first, then validate with an engineered quote. The Dissolved Oxygen 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

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.
