This is a an educational site for growing fish and plants in recirculating water - fish and plants in the same system

If you want to study this when on travel or in bed, you can load down a 10-page word-file by clicking here. Eventually you will be able to down-load a more extensive instruction on how to build a bigger hobby system or a professional system.

The town of Harnosand and the Rainbow Fisheries run an EU-project

The goal for this project is to develop and demonstrate the possibility to use fish farming in combination with plants on places with limited amount of water.

The recirculating system with ecological balance

Our construction is based on a growing system with water allways returning. In the process the water is cleaned and fish are cultivated in cooperation with tomatoes, cucumbers, lettuce and other plants without any poison and without any leakage to the surrounding nature.

Which are the advantages of this system?

Little consumption of water. The system can be a large industrial plant but can easily be adapted to the kitchen as a hobby system. The system is protected from the weather, storms, ice problems and diseases. No poison can be used - there must be ecological balance for the system to survive. The plants get the nutriment from the fish and the fish get clean water from the plants. The different components support each other and the products taste so much better.
For every kilogram the fish grow the plant produce 10 - 20 kg of vegatables.

Please come and visit us! See and learn!
