A study was carried out to observe the macrofaunal habitation in the coastal area of India’s first commercial atomic power station at Tarapur, Maharashtra. Macrobenthos are mostly sedentary as well as sessile in nature; therefore, they are used as indicator organisms to monitor health of marine ecosystem. The faunal record observed observed at experimental sites in Tarapur (TAPS1-4), consisted of 25 groups with 16 different polychaete families dominated by Nereidae, Capitellidae and Spionidae. Shannon - Wiener index (H’) was highest at Varor for faunal groups (2.07) and polychaete families (2.89) while lowest at anthopogenically stressed Uchheli (faunal group - 0.74) and Nandgoan (polychaete family - 1.67). Margalef’s species richness was highest at Varor (fauna -1.93 and polychaete family -1.61) and lowest at Nandgoan (fauna-1.00 and polychaete family - 0.74) due to dominance of environmental bioindicators, the polychaetes (Nereidae) as indicated by dendrogramme depicting Bray Curtis similarity and MDS Along with these observations, hydro-sedimentological parameters revealed comprehensive picture of community structure of macrobenthos and polychaetes’ families. The elevated water temperature was noticed at TAPS 3 and 4 (30.10C) which is under permissible limit (26-280C ±7) accompanied by pH (7.0). Dissolved oxygen was observed minimum at Uchheli (4.1mgl-1 ) and maximum at TAPS 1and2 area (7.5mgl-1).
