3 Conclusion
The temporal distribution of macro benthos exhibited
not only higher density during the pre-monsoon
season but also consisted of more diverse fauna low
benthic production, especially polychaetes, during
monsoon could be due to the low temperature and
salinity prevailing in that area. The decrease of
benthos in monsoon may be attributable to the low
temperature and salinity. A medium amount of organic
matter and salinity supports more benthic production.
So, it can be deduced from the study that ecological
factors like temperature, salinity and dissolved oxygen
have great influence on the abundance and distribution
of benthic organisms. Some species of polychaetes
were abundant more than other species i.e.g.,
Arabella
mutans, Capitella capitata, Cossura coasta,
Lumbrineris
sp
.
and
Pisionidens indica
in station 1
(Cuddalore). They are indicating the pollution of water
due to the State Industrial Promotion Council of
Tamilnadu (SIPCOT Cuddalore) discharging their
waste to the marine environment.
