Abstract
The present work aims to find out the biodiversity of marine organisms in
three different types of habitat along the Tuticorin coast using biodiversity indices.
These indices can be used more effectively in determining habitat qualities. For
the present study the three study sites namely, Sandy shore, muddy shore, and
Rocky shore located near Hare Island, Tuticorin coast, Gulf of Mannar were
selected. Tuticorin beach is known to have very low tides. A total of 2380
individuals belonging 38 taxa were identified from sandy shore, 698 individuals
belonging 13 taxa were identified from muddy shore and 630 individuals
belonging to 9 taxa were identified from rocky shore of Tuticorin. The phylum
Mollusca was the largest group on the sandy and rocky shore whereas the phylum
Cnidaria was the largest group in muddy shore. The Species composition and
quantitative characteristics of the marine organisms in Tutuicorin coast have
been assessed by using biodiversity indices- Shannon index, Simpson, Margalef,
Menhinick, Brillouin, Berger‐Parker Index, Fisher-alpha, Pielou Evenness
Indices and K dominance. The biodiversity was found to be high in all three
habitats along the Tuticorin coast and highest in sandy coast followed by muddy
and rocky coast.
