Chilika Lake 2012 Ecosystem Health Report Card, This is the first of a proposed series of annual Ecosystem Health Report Cards for Chilika Lake. Measuring the ecosystem health of Chilika Lake is conducted using 10 indicators organized into three main indices: Water Quality, Fisheries, and Biodiversity. Together, these indicators represent the ecosystem features of Chilika Lake that are valued (e.g., fishing, tourism, biodiversity); and represent the threats (e.g., overfishing and illegal aquaculture, pollution, and sedimentation) to these values.
