Intensive field studies were carried out at Pongibalu coral reef in the Mahatma Gandhi Marine National Park in South Andaman from March-September 2009 to investigate scleractinian coral diversity in the 3 predetermined plots on the reef covering a total area of 20,000 m2. A total of 76 species of hard corals were recorded with the live coral cover of < 50 percentage. Among the three plots, plot no. 2 harboured high species diversity with 43.3% live coral cover where existing concrete jetty acts as a substratum for the settlement and growth of the corals.Keywords

Andaman Nicobar Islands situated in the Bay of Bengal between 6°45´-13 45´N and 92°10´-94°15´E, consist of 352 islands 220 islets and rock and cover a distance of almost 470 km over North South, with a coastline of 1962 km, and bring in for India an Exclusive Economic Zone (EEZ) of 600 thousand sq km. The coast is under the influence of a diverse set of oceanographical and ecological conditions. The shelf topography of these islands show frequent rises supporting coral reefs, which are characterized as fringing reefs on the eastern side and barrier reefs off west coast; the depressions are known as passages and straits. Besides coral reefs, the shore is composed of rocky and sandy areas and vast stretches of Mangrove swamps, also few freshwater rivers and streams. A comprehensive and authoritative account of fishes of the Indian region including Andaman and Nicobar Islands was published by Francis Day (1870, 1875-78 and 1888). Herre (1941) listed 490 species of fishes. Talwar (1990) prepared a comprehensive list of fishes consisting of 724 species, followed by a supplementary list by Kamla Devi (1991) containing 71 species of fish. The recent developments in the fish taxonomy of these Islands are the works by Kamla Devi and Rajan (1991), Mishra and Krishnan (1992), Krishnan and Mishra (1992), Dhandapani and Misra (1993), Rajan (2001 a, 2001b, 2003, 2009), Rajan et al.

Rhodoliths are nodular form of marine free-living, non-geniculate, crustose coralline red algae, resembling the corals. The communities, in which they dominate are referred to as ‘rhodolith beds’, ‘rhodolites’ or ‘maerl’. Rhodoliths assume different sizes, shapes and forms (small thalli-like, twig-like, large round shaped, branching/unbranching, etc.) based on different factors such as water motion, bioturbation, grazing, fouling, bleaching, etc..Full Text

The status of reefs in Palk Bay and the Gulf of Mannar was studied during April–May 2016 following a bleach alert, as the sea surface temperature recorded a sudden increase from 30.5°C to 34.0°C in Gulf of Mannar. About 71.48% ± 8.9% of the corals in Palk Bay and 46.04% ± 3.78% in Thoothukkudi group of Islands in Gulf of Mannar were found bleached, showing a clearly decreasing trend from north to south, which could be attributed to the corresponding pattern in intensity of SST recorded in the study sites. Observations of bleaching patterns among different life-forms showed 68% of the bleached corals were massive forms. It was observed that 22 out of the 26 massive forms were bleached, while the Acropora corymbose (ACC), digitate (ACD) and encrusting coral (CE) forms were not bleached in any of the study sites in Palk Bay and Gulf of Mannar. The study suggests that the ACC, ACD and CE forms have adapted to thermal stress, subsequent to the earlier mass bleaching events. The study highlights the need for understanding the molecular mechanism of the association between corals and the symbiotic algae, for further understanding on coral bleaching in Indian waters.Keywords

Mount Harriet National Park is lies between 10°43’57N latitudes and 92°43’41 to 92°47’11E longitudes. The area of park is about 46.62 km2 (Fig. 1). The park possesses various hill ranges, which generally lie in the north and south direction of islands. From these, numerous spurs and ridges branch out in east and west directions. The hills are steeper on the east than on west. The principal peaks are Mt. Koyob (460m, the highest peak of N.P), Mt. Hext. (424m), Mt. Harriett (422m), Mt. Godridge (377m) and Mt. Carpenter (373m). The beaches on eastern coast are generally rocky with a few sandy patches.Full Text

Mount Harriet national park lies between 10°43'57"N latitudes and 92°43'41" to 92°47'11" E longitudes. The area of park is about 46.62 km2 and there is also a proposal to extend the area by another 1700 hectares to include the adjacent hill ranges on Southern part and to conserve the marine ecosystem along the Eastern coast (Fig. 1). The park possesses various hill ranges, which generally lie in the north and south direction as islands. From these, numerous spurs and ridges branch out in east and west directions. The hills are steeper on the east than on west. The principal peaks are Mt. Koyob (460m, the highest peak of N.P), Mt. Hext. (424m), Mt. Harriett (422m), Mt. Godridge (377m) and Mt.

Fusiliers are tropical Indo-Pacific marine perciform fish of the family Caesionidae and they are most associated with the reefs. Within the family there are 4 genera and 21 species (Carpenter, 1988 and Allen & Erdmann, 2008). They are colourful fishes; many have bright yellow stripes and patches. The caesionidae are related to the family Lutjanidae, the snapper fishes . The fusiliers posses s unique morphological features characteristic of their feeding mode. They are specialized for planktivorous feeding, while their nearest relatives, the snappers are typically benthic carnivores. The fusiliers possess a jaw morphology and body shape.Full Text
