Abstract
Dwarka coast of Gujarat state from India has a stable shore platform. For this study, the shore platform was divided into three sections: i) northern, ii) central and iii) southern. Macroalgae growing on this shore platform were surveyed based on systematic random sampling for three months in sequence (April, June and October, 2013). On this site, total 36 taxa of macroalgae were identified through intensive fieldwork/ in situ survey based on Line Intercept Transect and Quadrate based methods. An overall analysis of the field data so far collected reveals that Chlorophyta dominates in the subtidal zone while Ochrophyta (Phaeophyta) dominates in rock pools near the cliff base as their preferred habitats. Rhodophyta showed a seasonal predominance during June. Iyengaria stellata was found in all the three months. The result obtained in this study provides an insight to understand the macroalgae habitat zonation on the shore platform and can be useful to support conservationof this study site as a rich macroalgae habitat of Indian Coast.
