Recirculation Aquaculture Systems (RAS) basically consist of culture tanks for aquatic organisms and a water treatment system that is designed to maintain optimum conditions for the culture species. This allows the water to be recycled continuously.
ACE has build and designed 5 Eel farms over the last 4 years, ranging from a production capacity of 20 tons per year to 200 tons per year. These farms included 17 separate recirculation systems, either for raising glasseel to a size of 2-5 grams or for ongrowing of the 2-5 gram Elvers to market weights of 135-200 gram.
