Diatom Diversity in Hypersaline Environment

A. Nagasathya and N. Thajuddin

Abstract

The present study is the first detailed investigation of the diversity and distribution of diatoms in relation to the hydrography in the Saltpans of Southern coasts of India starting from Vedharanyam to Mandapam. Totally 52 taxa, both centric and pinnate diatoms were identified in the present investigation. When compared to Palk Strait and Palk Bay regions less diversity of diatoms was observed in the Bay of Bengal region. Highest diversity of diatoms was observed in the 50 ppt. But only 4 taxa namely Achnanthes hauckiana, Cyclotella striata, Pseudonitzschia seriata and Thallassionema eccentrica were observed at higher salinity (150 ppt).
