Totally five species of seagrass belonging to four
genera were recorded in the present study. The
dominant species recorded here are Halodule,
Cymodoceae and Halophila. All the five species were
recorded in Chidiyatapu and three specie in North Bay
but no seagrass species were recorded in Viper Island.
In the present study the lowest temperature
(28.8°C) recorded in September 2007 and the highest
temperature (29.7°C) recorded in December 2007.
Salinity 29.00‰. In September 2007 and 30.5‰ in
December was recorded. pH 7.3 and 7.8 were recorded
in September 2007 and December 2007 respectively .
The lowest (5.2 ml/l) Dissolved Oxygen (DO) was
measured in the month of December 2007 and the
highest DO was observed in September 2007. There
exist a correlation between the occurrence of marine
algae and environmental parameters like temperature,
salinity, pH and Dissolved Oxygen (D.O). An increase in
dissolved oxygen and decrease in temperature, pH and
salinity were associated with heavy rainfall that favored
the growth of algae.
The present study area is rich in species diversity
than the Rani Jhansi Marine National park, Andaman
(Marcel Tigga and Rao, 2004) but less than that of
Nicobar Biosphere reserve (Kannan and Thangaradjou,
2006), while compared this algal diversity richness to the
other country algal diversity, it revels that the coastal
area of Andaman sea is more suitable for algal collection
