| Abstract: | To study the impact of integrated lotus-soft shelled turtle system on the water quality and the growth properties of lotus and soft shelled turtle, water quality, species and quantity of zooplankton and phytoplankton in the soft shelled turtle monoculture system, lotus-soft shelled turtle coculture system and lotus monoculture system were investigated monthly from Jun to October, 2019. The results showed that the concentrations of ammonia and COD significantly decreased under the integrated lotus-soft shelled turtle system compared with soft shelled turtle monoculture system. The species and diversity indices of zooplankton and phytoplankton did not differ among the three systems significantly. The protozoan, rotifer and copepods were the dominated zooplanktons species in the three systems. For the monoculture system, species of green algae and blue-green algae mainly dominated the phytoplankton populations, while green algae, diatom blue-green algae and euglena dominated the phytoplankton populations in the integrated system. The survival rate and specific growth rate in the integrated system increased by 23.29% and 1.59%, respectively. In the meanwhile, the FCR was 17.92% lower than the soft shelled turtle monoculture. Compared with those of the system of lotus monoculture, 100-grain weight and the number of lotus seedpods of the integrated system were increased by 9.76% and 7.23%. |
