Abstract:With Polycheate Neanthes japonica as a forage animal for Penaeus chinensis , the organic matter energy budget, biological energy flow and energy turnover efficiency for shrimp pond ecosystems of Qingdui District in Zhuanghe of Liaoning Province were studied. By experiments in 4 ponds, the total energy of input and productive organic matter was estimated 13725 kJ/m 2 on the average.The primary production was 7 524 kJ/m 2, and input artificial diet was 6201 kJ/m 2 Total output was 10359 kJ/m 2,8 ...
