Abstract

On the west coast of India live hermatypic and ahermatypic corals were encountered in close vicinity of nuclear power plant site at Tarapur, Maharashtra, which has been working successfully since 1964. The patchy growth of three hermatypic coral genera, viz., Goniastrea, Goniopora and Porites were observed at intertidal area of intake channel of TAPS 3 and 4 (500 m, SE), Varror (8.4 km, NE) and single ahermatypic coral species at Light house (1 km, NE). The corals in these areas were small in size and appeared to be not more than few years old. The water temperature, salinity pH and turbidity were in the range of 27.50C to 29.90C, 34.5 ppt to 36 ppt, 7.9 to 8.2 and 10 NTU to 21 NTU respectively. Sediment texture was mainly dominated by sand (81.9 % to 86.6 %) followed by silt (6.75 % to 10.5 %) and clay (5.6 % to 7.7%) and organic carbon was in the range of 0.78 (%) to 1.98 (%). The occurrence of corals indicates that they got adapted to the range of salinity which tends to vary seasonally and turbidity due to strong wave action. It was observed that the corals got affected due to fishing activities rather than discharge from TAPS and therefore efforts are needed to protect them.
