Phytoplanktons are the primary producer of marine ecosystems and contribute towards the primary productivity of aquatic environment. The present study was carried out at three selected sites of Gulf of Kachchh (GoK) viz; Pirotan, Sachana and Roziport. During the study, a total of 106 species of phytoplankton were recorded, of which the highest species diversity was found at Rozi followed by Pirotan and Sachana. The maximum number of species diversity was contributed by the class Bacillariophyceae with 81.5 percentage , 79 percentage and 83 percentage at Pirotan, Rozi and Sachana, respectively. Rozi port reported the highest number of harmful phytoplankton i.e. some members of Bacillariophyceae and Dinophyceae. The highest number of species was recorded at Rozi port (75 sp.) followed by Pirotan (54 sp.) and Sachana (46 sp.). The varied environmental conditions prevailing at three study sites may cause variation in species composition at these sites.

The monitoring of coastal water quality was done on seasonal basis in pre-monsoon, monsoon and post-monsoon for three years duration (November 2011 to December 2014). Data obtained were applied to Arc-GIS software 10.3 for the preparation of thematic maps to evaluate the spatial and temporal variation in water quality parameters. Cluster analysis showed formation of two clusters which grouped 17 sites in two dominant ecosystems namely mangrove and coral.
