Abstract :

The coral reef of the Andaman and Nicobar Islands encompass significantly diversified faunal component of the Indo- Pacific Ocean. The present study on corals was designed to assess the status, population diversity and abundance at Mayabunder region. A total of 43 corals belonging to 30 species, 15 genera, 8 families were distributed widely in the study area. More number of species belonged to the Family Acroporidae (11) and Fungiidae (9) and the coral species composition was less in the Families Faviidae (4) and Pocilloporidae (2); and other families viz., Agariciidae, Oculinidae, Siderastreidae and Euphyllidae which were represented with only a single specie. The diversity index (H') of corals at Mayabunder ranged from 2.32 to 4.52. Mean density and relative abundance of corals were higher for Acroporidae and Fungiidae when compared to other families. The maximum number of coral species was present in Avis Island (48) followed by Sound Island (30), Curlew Island (9), Karmatang beach (7) and Rail Island (5).
