| Abstract/Description: | 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. |
