Abstract: The East Calcutta Wetlands is one of the largest wastewater-fed aquaculture in the world. It is the aggregation of salt marshes, salt meadows and wastewater-fed ponds that receive wastewater from various small and large scale industries and urban settlements. The available nutrient supports the grazing food chain of the wetland ecosystem and agriculture around it. Eutrophication is caused by the imbalance between nutrient load and utilization by the autotrophs in the system. In this wetland, there has been a gradual decrease in the fish production for the last few decades. The physical and chemical conditions of the system are deteriorating continuously. Therefore, modelling of the system is felt to be the need of the hour to mitigate the problem of eutrophication and identify the important parameters that govern the system dynamics.
