Distribution and Zonation of Seagrasses in the Palk Bay, Southeastern India

S. Manikandan, S. Ganesapandian and K. Parthiban

Abstract:
The distribution and zonation pattern of seagrass was assessed by SCUBA diving assisted with Global Positioning System (GPS) and 100 M transects at every 0.5 km, in the area between Mandapam and Thondi in the Palk Bay during March-July 2009. The study area has been divided into 3 regions, viz., Mandapam, Panaikulam and Thondi. Seagrass were distributed in about 175.2 km-2 coastlines in the study area. The percentage of seagrass distribution and species composition in Mandapam it was 63.87% in nearshore with 10 species, 43.56% in middle zone with 7 species and 26.27% in offshore with 4 species. Likewise in Panaikulam it was 24.17% in nearshore with 7 species, 53.31% in middle zone with 6 species and 20.14% in the offshore 5 species. Where as, in Thondi it was 75.41% in nearshore with 9 species, 54.28% in middle with 8 species and 31.42% in offshore with 7 species. Overall all the 14 species were observed among the Cymodocea serrulata was the most abundant species and the least was Enhalus acoroides in these study region. Shoot density and biomass of 14 species of seagrass and epiphytic biomass in different zonation were analyzed. This study gives clear cut idea about distribution and zonation of seagrass in Palk Bay region.
