Abstract:

Seaweed diversity assessment at Hare Island in the Gulf of Mannar revealed presence of 99 seaweed species belonging to 15 order, 24 family and 42 genera during May 2014 to April 2015. Recorded species during present study belonged to 3 phylum. Rhodophyceae was dominant seaweed phylum with 35 species belonging to 7 order, 12 family and 20 genera followed by Chlorophyceae (33 species belonging to 4 order, 8 family and 11 genera) and Phaeophyceae (31 species belonging to 4 order, 4 family and 11 genera). Seasonal variability in various diversity indices were calculated by using PRIMER v6 software. The calculated value of biodiversity indices showed healthy nature of seaweed ecosystem at Hare Island.
