In our project we mainly focus on the mulberry dike-carp pond farming system in south of China (Zhujiang Delta). It is an example of typical agroecological system with high efficiency. After we study based on such a kind of system, we found the yield of this system is high and the waste of energy is low. In order to comprehend the mulberry dike-carp pond farming system better, we learned the energy flow in the ecosystem, and calculated the efficiency of the system with the help of ecopath program. We calculated the production efficiency by using ecopath. The result tells us that the mulberry dike-carp pond system is really an efficient system. We will try to improve the efficiency by changing the structure of the fish community in the pond.
