Intrusion of Abiotic Domain and Atrophy of Aquatic Biodiversity in Chilika Lake

This paper reviews the quintessential and contemporary conditions of the Chilika Lagoon, accentuating the adverse effects on abiotic species leading to decline of biotic species. The largest biodiversity hotspot on eastern coast of India. Chilika is the largest brackish water lake in Asia which presents an attractive and unparalleled fusion of marine, river, and estuarine habitat that supports unique conglomeration of marine, brackish water and freshwater microbes. Abiotic effects of siltation and salinity, has led to parallel loss of biotic species due to the changes in microbial community of phytoplankton, and abasement of lake ecosystem owing to the freshwater invasive species thereby declining the overall fertility of the aquatic biodiversity.
