To find out a clear picture of species diversity and distribution,
various univariate and multivariate analyses have been carried out and
results are discussed. Individual species is a simple and useful measure
of the biological system. The species individual diversity in the present
study registered a wide fluctuation between 4.311 (monsoon) and 5.167
(summer) among stations and seasons. The lower species diversity was
recorded during monsoon and higher diversity values during summer
in the study area. This is in conformity with the earlier observations
made in Vellar [51] and Coleroon estuaries [31]. Moreover, Pearson
TH and Rosenberg R [52] proposed that the use of diversity indices
is advantageous for the description of fauna at different stages in
succession. In the present study, negative correlation is obtained
between species richness and diversity at stations I (r=-0.999), II (r=-
0.997) and III (r=-0.999) at p
