Abstract

Marine ecosystem is known to be one of the richest amongst the entire living ecosystem.Coastal macrofaunal species are part of specific ecosystems assessing the condition of ecosystem, and considered asa useful indicator of threats to the diversity of coastal regions. Kathiawar Peninsula (Gujarat State, India) has a vast coastal line and the availability of varied types of substrate on this coastal line makes it a suitable place for rich biota.The present investigation was carried out to study the present ecological status of Cellanaradiata at Dwarka sea coast, Gujarat, India. C.radiatais a most dominating mollusk species that are found mostly on the upper and upper middle littoral zone of the rocky intertidal substratum. C.radiata was found to stick themselves on the vertical rocks of the pools and the creeks. This helps them to move along the upcoming tidal water for food from water. As they are covered with a very hard and solid shell, fluctuation in physical condition hardly brings any change on their distribution. It was observed from the present investigation that the frequency values did not show any definite spatio-temporal trend at the sites. It was evident that no significant difference of the population abundance existed between the sites as well as among the seasons.
