y most <strong>of</strong> the organisms. It was also noted in the present study that, DO was<br />
comparatively high during pre-monsoon <strong>and</strong> low during post-monsoon. This high<br />
DO value during pre-monsoon might also have positively influenced high benthic<br />
biomass in this season when compared to post-monsoon. Correlation analysis showed<br />
that (Table 27), during post-monsoon, total biomass <strong>and</strong> biomass <strong>of</strong> polychaetes,<br />
molluscs <strong>and</strong> miscellaneous groups were positively correlated with DO while<br />
crustaceans were negatively correlated. During pre-monsoon, total biomass <strong>and</strong><br />
biomass <strong>of</strong> polychaetes <strong>and</strong> miscellaneous groups were positively correlated with DO<br />
whereas crustaceans <strong>and</strong> molluscs were negatively correlated. For density,<br />
correlation analysis showed that (table 28) all benthic groups were positively<br />
correlated with DO except molluscs during post-monsoon season, <strong>and</strong> the relation<br />
between crustaceans were at significant level (r=0.423, p
