From fish to tomato

Conventional aquacultures discharge high concentrations of nutrients into the environment, due to fish excrements and fish food residues in the effluent. From fish to tomato presents a polyculture system that combines aquaculture with vegetable or fruit production. In this so-called aquaponic-technique water and nutrients are recycled. The aquaculture effluent runs through planted beds where it is cleaned by the combined action of plants and bacteria. The cleaned water then flows back into the fish tanks. Thus, waste is converted into useful biomass, such as lettuce, strawberries or tomatoes.
