The constructed mass balanced Ecopath model illustrates the trophic interactions among 22 defined functional groups of Chilika lagoon ecosystem. The estimated trophic levels (TL) in this model are in the range of 1.0 to 3.416. Elopiformes were found as the top predator with a TL value of 3.416 followed by Belonids (3.411). Zooplankton was found as the most utilized group expressing the highest ecotrophic efficiency of 0.944. Network analysis of the model indicates a mean transfer efficiencies of 8.233% from primary producers and 6.198% from detritus. The ecosystem indices: total primary production/total respiration (7.803), Finn’s cycle index (1.662), mean path length (2.185), connectance index (0.460), system omnivory index (0.237), ascendancy (47.38) and overhead (52.62) were estimated by the model. The estimated pedigree index (PI) of 0.5 for the present model indicates the ecopath model of the lagoon is a robust model. The indices indicate that the Chilika lagoon ecosystem is on its developing stage and possessing a stable ecosystem with a moderate resilience capacity to overcome the perturbations.

构建的质量平衡的Ecopath模型说明了Chilika泻湖生态系统的22个定义的功能组之间的营养相互作用。此模型中的估计营养水平（TL）在1.0到3.416之间。发现蛇形目是最大的食肉动物，TL值为3.416，其次是Belonids（3.411）。浮游动物被发现是利用最丰富的群体，其最高的生态营养效率为0.944。该模型的网络分析表明，初级生产者的平均转移效率为8.233％，碎屑者的平均转移效率为6.198％。生态系统指数：总初级生产力/总呼吸（7.803），芬氏循环指数（1.662），平均路径长度（2.185），连接指数（0.460），系统杂食性指数（0.237），优势（47.38）和开销（52.62）由模型估算。估计的系谱指数（PI）为0。本模型的图5表明泻湖的生态路径模型是鲁棒模型。各项指标表明，Chilika泻湖生态系统处于发展阶段，拥有一个稳定的生态系统，具有适度的抵御干扰的能力。
