Recirculation Aquaculture Systems (RAS) for fish farming are characterized by an integrated water treatment unit that constantly cleans the effluent water from the fish tanks. Advances in technology allows a very high degree of water re-use; normally in the range of 95-99% compared to water consumption in a flow through system.
Recirculation systems for different species of fish are currently being built all over the world.
However, the multi-tier concept of Cube 2 is unique in its vertical design with independent RAS modules on each level. The production units are customizable to suit a wide range of different species of fishes and shrimps.
