Next Generation Aquaculture Technology

Our advanced integrated Recirculating Aquaculture System (RAS) technology offers maximum control, minimum maintenance and ultimate sustainability.

Working with nature, we leverage cutting-edge technologies and tailor them to the needs of the industry, to ensure that aquaculture installations of the future will be more sustainable, deliver improved efficiency and productivity, provide traceability and food safety, while enhancing fish quality.

Systems & features

  • Oxygen Dissolving System (ODS)

    • More Oxygen with less energy
    • Oxygen generated on site
    • Waste heat recovered
    • Oxygen level regulated in each tank
  • Filtering system

    • 100% of water goes through filter treatment with every cycle
    • No bypass loops
    • Aerobic bioreactors are used for nitrification and PH balance
    • Anaerobic bioreactors are used for denitrification and alkalinity adjustment
    • Improved solid waste separation without drum filters
    • High efficiency AquaMaof trickling filter: adds oxygen and removes CO2,uses no pumping – only gravitation flow, and has optimal water distribution
  • Settling Filter

    • The second step in the solid waste removal process
    • Contains media through which the water flows.
    • The discharged water slowly percolates upward - any heavier than water solid particles settle on the floor
    • Improved solid settling capability and reduces the total basin without media.
    • Provides some denitrification of the nitrate (nitrogen) content of the water.
  • Biofilter System

    • The Biofilter is a non-mechanical water treatment system for growing bacteria on a filter media designed to provide a large surface area in a small volume.
    • The growing process of bacteria neutralizes toxic fish wastes into by-products that are not harmful.
    • Water flow from the Settling Tanks is controlled automatically.
    • The bacteria convert fish waste products, oxygen and alkaline water into nitrate, carbon dioxide, and hydrogen ions.
    • The nitrification of ammonia is a two phase process. First, converting ammonia to nitrite and second, converting nitrite to nitrate.
  • Fish transfer system

    • Harvesting of the fish is carried out when they have reached their desired weight in line with the Fish Stock Management Plan.
    • The fish are transferred stress-free, from and between the tanks via the Harvest Channel.
    • A Fish Screw Elevator (Pescalator) transfers fish from the Harvest Channel to the Fish Grader
    • A Fish Grader sorts the fish into prefixed sizes, undersized fish returned to the tanks for further breeding.
  • Harvesting and grading system

    • The Harvest Channel is a rectangular cross-section channel located between the Production Tanks. It is connected to each tank by a "monk" door.
    • After the monk is opened, the fish are pushed into the Harvest Channel using a fish pusher.
    • After all fish are in the channel the monk door is closed to prevent the fish from re-entering the tank.
    • The Fish Screw Elevator is based on the Archimedes Screw concept, gently rotating to elevate the fish into the Grader while keeping the fish in water at all times.
    • The grader is located adjacent to the processing plant load area or packaging and dispatch hall.
  • Monitoring & Control

    24/7 monitoring of all critical system components and water parameters, providing alarm signals and SMS (texting) notification of critical faults. Moreover, the system automatically activates emergency backup systems including electricity generator, oxygen supply, process. Monitored parameters:
    • Water: level, temperature, dissolved oxygen, pH, ORP, NH4-N, NO2-N, NO3-N, ALK, P, K, TDS
    • Environment: temperature, relative humidity, air change
    • Equipment: biofilter, pumps, blowers, oxygen generator, feed system
  • Industrial Production Tanks

    • The AquaMaof fish production tanks are designed to hold the growing fish as well as removing some of the solids from the water.
    • A sediment trap for collecting fish waste solids is located in the center of the production tank and is covered by a grid and fine mesh screen to prevent the fish from escaping.
    • The production tanks have an individual Feeding System and "monk" gate openings for exiting the fish into the Harvest Channel.
  • Bio-Security Control

    The facility is designed in accordance with strict bio-security protocols.
    • Quarantine
    • Disinfection
    • Staff movement control
    • Safety procedures for entering and exiting the facility
    • SOP's
