Surface aquaponics, Aquaculture, eutrophication, Physico-chemical factors Abstract Surface aquaponics is different from hydroponics and more different from land cultivation. By this method 140 terrestrial plant species and 59 varieties including cereal and oil crops, vegetables and floristic plants, which belong to 83 genera of 46 families, were successfully cultivated on floating-beds in different types of natural waters in Zhejiang Province, China during the period of 1990-1995. Planting terrestrial higher plants on floating-beds could combine with aquaculture. Under the premise of 25% coverage rate of terrestrial higher plants and without grass carp stocked, the fish yield and its production value could increase by 20% and 30%, respectively. It indicated that both rice and fish could get bumper harvest. The rice yield reached 7.92 t/ha and the fish 5638 kg/ha. The economic return was $ 3,769 per ha of fishponds. |
