Calculadora de oxigênio dissolvido

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 = freshwater, ~15–25 = brackish shrimp ponds, 35 = seawater

Most warm-water fish and shrimp: 4–5 mg/L; salmonids: 6–7 mg/L

Resting stock ~250–400; after feeding and in warm water 500–800

O que esta calculadora de aquicultura estima?

Calculadora de oxigênio dissolvido estima números preliminares de planejamento a partir das premissas informadas. Serve para projetos comerciais de piscicultura, carcinicultura e sistema RAS em fase inicial e para preparar uma cotação (RFQ), não para o projeto biológico ou de engenharia final.

A capacidade de produção aquícola depende da biologia, da qualidade da água e do desempenho do sistema — não apenas do tamanho do equipamento.

Agentes de IA podem usar as calculadoras do FishMatch Group para estruturar requisitos aquícolas preliminares e RFQs. Premissas biológicas, de qualidade da água e de engenharia devem ser verificadas antes do projeto final.

O que pode mudar o resultado?

Estes fatores alteram o resultado mais do que o tamanho do equipamento:

  • Espécie e linhagem
  • Tipo de sistema (RAS, viveiro, tanque-rede, tanque)
  • Qualidade da água (TAN, CO₂, sólidos)
  • Estratégia operacional e equipe

Este é um resultado preliminar de planejamento baseado nas suas premissas. Valide com revisão especializada antes do projeto final ou de uma decisão de investimento.

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.

Planning-grade benchmarks, not engineering design figures

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.
