Aquaculture en recirculation (RAS) : questions fréquentes

Réponse rapide

Un système d'aquaculture en recirculation (RAS) est une ferme piscicole terrestre qui nettoie et réutilise la majeure partie de son eau grâce à une filtration mécanique et biologique, un dégazage, une oxygénation et une désinfection, permettant une production élevée avec un contrôle précis.

Fonctionnement d'un RAS

  • La filtration mécanique élimine les solides
  • Le biofiltre convertit l'ammoniac en nitrate
  • Le dégazage élimine le dioxyde de carbone
  • De l'oxygène est ajouté
  • Les UV ou l'ozone désinfectent l'eau
  • L'eau propre retourne dans les bassins

Short answer

What is the fastest way to get quotes for RAS FAQ?

Submit one structured request for RAS FAQ. 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
Cost to buyers:
No fee charged to the buyer

How does FishMatch Group source suppliers for this requirement?

You submit one structured request. We translate it into a technical RFQ, run it against qualified manufacturers and integrators in the relevant categories, and return normalised quotations you can compare side by side on scope, lead time and total cost of ownership.

Do buyers see supplier names during the sourcing process?

No. Supplier identities stay confidential during discovery and evaluation. You receive anonymised, comparable technical and commercial packages, and introductions happen only after both sides are qualified and agree to proceed.

Before you request quotes

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.
