Chilika is the largest brackish water lagoon of Asia and lies in the east coast of India. Because of its rich fishery resources, the people who are living in and around the lagoon depend on the lagoon for their livelihood. It is a unique assemblage of freshwater, brackish and marine eco-systems and is known for its rich diversity of fish species.
A review of the inventorisation of recorded fish fauna published by Mohaty et al. (2006) reported 230 species comprising 71 families while Rama Rao (1995) listed 217 fish species comprising 71 families. However, 210 species have been enlisted in the Fish base website. An updated compilation of all these species makes a total of 318 species comprising 83 families and 20 orders. The present investigation recorded 152 fish species belonging to 61 families and 17 orders during 2003. Out of this collection, 43 species are included as new records which were mostly marine and they might have entered into the lagoon through its mouth during high tide. Out of 152 fish species recorded, 25 species inhabit fresh water, 91 species brackish water and 36 species marine habitats of the Chilika lagoon.
