Description A study was conducted to evaluate the phytoplankton community
structure and its relationship with selected physicochemical variables in
the inshore waters of Tuticorin during January to December 2008. Water
and plankton samples from the surface waters at two depths (5m and
10m) were collected on board the research vessel Cadalmin-IV. Standard
methods were followed for phytoplankton identification, enumeration
and estimation of physicochemical variables. The present study recorded
69 species of phytoplankton with 85.5% dominance of diatoms
followed by 14.5% of dinoflagellates. The overall density of
phytoplankton was comparatively higher at 10 m with a mean of
2.14x104
±0.4x104
cells L-1 and 3.37x104
±0.9x104
cells L-1 at 5 m and
10 m depth respectively. The analysis indicated that 10 m depth,
especially during the monsoon season, is rich in diversity of algal species
than at the same depth during post-monsoon. It is confirmed that the
population density of phytoplankton is more influenced by seasonal
fluctuation of the physicochemical variables especially due to the effect
of northeast monsoon in the inshore waters of Tuticorin.
