01 / The System

A fish stable in the middle of your farm

Our land-based fish farming system makes catfish production an integrated part of the farm’s ecosystem. You own and operate the fish stable, while we provide the system, fry, feed, software and PLC automation. Fish enter as fry and leave ready for processing, while nutrient-rich water and manure are returned to your fields as irrigation and fertilisers.

Closed loop

FISH IN, FISH OUT, MANURE AND WATER BACK TO THE LAND

A freshwater species was chosen deliberately: the wastewater can be spread on fields, and all fish waste becomes fertiliser. The farm becomes self-sufficient on high-quality manure.

  1. 01

    System construction

    We build and install your new fish stable and ensure that everything is ready for the first fry.

  2. 02

    FRY

    From our own hatchery, 13 600 fry is moving in to your module. In 5.5 months they have grown to 2.2kg.

  3. 03

    Grow-out

    We continuously optimise the grow-out using the latest aquaculture technique and real-time data from your farm.

  4. 04

    Fields

    Nutrient-rich water and solids go straight onto your own land for irrigation and fertiliser.

  5. 05

    Crops

    One stable producing 400 MT/year fertilises 100 hectares of arable land.

WHY CATFISH

CATFISH - THE MOST OPTIMAL FISH TO FARM

Omnivores

Our fish are omnivores, so they can be raised on a higher proportion of plant-based feed than other common species. This minimises overfishing.

Tough

Robust enough to live together without getting sick. They have never needed medication.

ECOSYSTEM

A freshwater species was chosen so the wastewater can be spread on fields. All fish excrement is turned into manure. This minimises eutrophication of our ocean.

Low FIFO

Today we are a net producer of fish with a FIFO of 0.7. Because catfish is an omnivore, it is possible to completely remove fishmeal and fish oil from the feed.

Control room

Every tank, on one screen

PLC-based control handles feeding, water quality and alarms. Growth, FCR, biomass, water quality, feeding, mortality, energy and temperature stream to the cloud, where the platform analyses, learns, optimises and deploys improvements back across the network.

Farmer economics

Built for your farm

  • Increase use and profitability of land you already own
  • Low CAPEX compared with other livestock buildings
  • Minimal time spent, thanks to the automation platform
  • The farm becomes self-sufficient on high-quality manure
The partnership

Aquaculture as a service

The farmer owns and operates the production facility. Scandinavian Aquasystems provides and continuously develops the technology behind it. More farms create more data, more data creates better performance, and every improvement is deployed back to the network.
