Abstract

Diversity of intertidal macrobenthic community and environmental parameters namely temperature, salinity, pH and DO were assessed near the proposed nuclear power plant site Jaitapur from 2012 to 2014. Analysis of macrobenthic samples revealed the presence of 54 species belonging to 19 different groups. Highest diversity (14 groups) was observed during the post-monsoon (2014) season. At sandy and rocky shores, polychaetes were dominant followed by crustaceans like amphipod, isopod, penaeid shrimps and decapod larvae. Among all inshore stations, diversity was found to be maximum at Ganeshgule (N SW30 kms). Shannon-Weiner diversity index (2.259) and Margalef’s species richness index (2.502) indicated rich diversity at rocky habitats (N SW30 kms). The present study suggests the stable environmental parameters around the Jaitapur Nuclear Power Plant (NPP) sites and is responsible for the rich benthic community. The outcome of the present study may be useful as baseline information on macrobenthos around the proposed Jaitapur NPP site.

印度西海岸马哈拉施特拉邦Ratnagiri和Sindhudurg地区潮间带大型底栖动物的多样性

2012 - 2014年对斋塔普尔核电站拟建场址附近潮间带大型底栖生物群落多样性及环境参数(温度、盐度、pH和DO)进行了评价。对大型底栖动物样本的分析显示，存在属于19个不同类群的54种。在季风后(2014年)季节观察到最高的多样性(14个类群)。在沙质和岩石海岸，多毛类占主导地位，其次是甲壳类，如片足类、等足类、对虾类和十足类幼虫。在所有近岸站中，甘尼什古尔站(西南30公里)的多样性最大。Shannon-Weiner多样性指数(2.259)和Margalef物种丰富度指数(2.502)表明岩石生境(西北SW30 km)具有丰富的物种多样性。本研究表明，斋塔普尔核电站场址周围的环境参数稳定，并对丰富的底栖生物群落负责。本研究的结果可能是有用的基线信息周围的大型底栖动物的提议的斋塔普尔核电站站点。

期刊介绍： Started in 1972, this multi-disciplinary journal publishes full papers and short communications. The Indian Journal of Geo-Marine Sciences, issued monthly, is devoted to the publication of communications relating to various facets of research in (i) Marine sciences including marine engineering and marine pollution; (ii) Climate change & (iii) Geosciences i.e. geology, geography and geophysics. IJMS is a multidisciplinary journal in marine sciences and geosciences. Therefore, research and review papers and book reviews of general significance to marine sciences and geosciences which are written clearly and well organized will be given preference.
