Abstract: In 2013, experiments on raising different aquatic animals including fish,turtle,loach and crayfish in paddy fields were carried on in Nanping city,mountain area of Fujian.Six test sites were established, the total area was 73.33 hm2.The result showed that, due to the ecological effect in paddy fields,the rice yield maintained steady, although six test sites didn’t use pesticide and fishery medicine at the meanwhile.The rice yield of the traditional singular planting mode was 495.7 kg/667m2 and the unit profit was￥439/667m2 ,while the average yield of rice and aquatic animals of the ecological cultivation modes were517.2 kg/667m2 and 60.6 kg/667m2 respectively, and the average profit was ￥2 183/667m2,increasing ￥1 744/667m2 compared with the traditional singular mode,5.0 times as much as the singular mode.Compared with the singular planting mode,the mode of rice-turtle symbiosis,rice-fish symbiosis, rice-crayfish rotation and rice-loach symbiosis were 34.7 times, 5.0 times,3.4 times and 1.7 times respectively as much as the former. Among the paddy-fish cultivation mode, the average profit of Wuyi site was 10.2 times as much as the singular planting mode.In conclusion, the paddy ecological cultivation mode was a good example for developing ecological efficient aquaculture and rice faming.
