Seafood holding systems

Aquaculture France offers a wide range of tanks for the storage, presentation, and purification of seafood products. All our tanks are equipped with a filtration unit, UV sterilization, and temperature control. The size of the cooling unit and the dimensions of the filtration system are determined based on the species and maintenance temperature.
The structure of the tanks can be made from bonded glass, single or double glazing. We also use PMMA, which prevents condensation and offers better thermal performance.

All options and accessories are available:

Casters
Handrails
Cover
Start-up kit including synthetic salt, freeze-dried bacteria, and water quality test kits.

  - Size varies depending on the volume of shellfish.
2. Water circulation system:
  - Natural or artificial seawater, sterilized by UV or ozone.
  - Controlled flow or recirculation.
3. Disinfection system:
  - UV lamps or ozonation to eliminate pathogens.
  - Continuous water quality monitoring.
4. Parameter control:
  - Temperature, salinity, pH, dissolved oxygen.
  - HACCP compliance and full traceability.
Benefits:
- Ensures shellfish are microbiologically safe.
- Meets EU and international health standards.
- Enhances product taste and quality.
- Allows direct marketing after treatment.
