Fish & Salad
AKVA group steps forward towards industrial aquaponicsImage: Testing greenhouse in Copenhagen.
Growing plants and fish together has already been accomplished over a thousand years ago in ancient China. The plants grow by using the nutrients excreted from the fish, and both fish and plants can be harvested for consumption. Modern aquaculture combined with hydroponics (culturing plants in water) is called “aquaponics”, and the technology is about to become industrialized.
Together with Dr. Paul Rye Kledal, founder of Institute of Global Food & Farming (IGFF), AKVA group has developed and built a small scale aquaponics system in an existing greenhouse research facility near Copenhagen. System includes fish rearing tanks and salad tables together with a recirculating water system with two independent water loops.
One of the loops run through a water filtering system and can be routed to plant tables or back to fish tanks. The other loop supplies water directly to plant tables for growing lettuce or herbs such as sage, basil and thyme.

Dr. Paul Rye Kledal: ‘The aquaponics test plant we have designed in cooperation with AKVA group will be modified to fit our new plan for a 3.000 m2 semi-commercial pilot production on ground. In my vision we are cooperating with
AKVA group for them to have a first mover position on their products and skills within this novel area.
As a research driven company we can support documentation on the various factors associated with aquaponics as well as to help eliminate risks.’
IGFF is currently in close cooperation with Copenhagen municipality of installing a Roof Top Farm of 400 m2 aquaponics production as part of an educational and more visionary platform integrating food production with urban farming aimed for climate resilient cities.
Copenhagen municipality has some strong goals of being CO2 neutral in 2025, and proposing more green roofs as part of stopping the huge costs and damages from ‘monster rains’.
The roof top farm will be a show case of a productive green roof utilizing the rainwater in aquaponics production and taking advantage of a very short supply chain of fish and vegetables between producer and consumer.
