Abstract

The present study deals with the distribution and abundance of macrobenthic community in Nalaban Island, Chilika Lagoon. Five macro-invertebrate groups viz., gastropods, pelecypods,
isopods, amphipods and polychaetes were recorded. Gastropods (75.7%) comprised the most abundant group of macrobenthos followed by pelecypods (16.9%), isopods (4.9%), polychaetes (0.35%) and amphipods (0.07%). The species diversity index showed a wide range of higher
H values indicating a stable benthic community with absence of environmental stress. Further, the community structure did not show any significant spatial variation in species composition.
Interestingly, significant correlation was noticed between gastropods and isopods. Further, the statistical analysis confirmed that there exists significant variation within the molluscan species rather than variation within stations
