Description 2223-2232
In the Arabian Sea,
organic matter produced during the upwelling period reaches the seafloor by the
end of the monsoon and during the fall intermonsoon period (FIM). Studies on
the benthic community is lacking during this period. Therefore, we predict that
the FIM period is critical in structuring the coastal benthic community. Results
indicated Coscinodiscus sp. and Thalassiosira sp. were dominant in the
phytoplankton and the microphytobenthos community. Zooplankton was dominated by
small sized calanoid copepods followed by larval forms of polychaete and fish.
Macrofauna was dominated by the juveniles of interface feeding polychaete, Paraprionospio pinnata. The quality of
food from the surface flux supported the macrofaunal community and explained
the successful recruitment of dominant P.
pinnata.  Therefore, species
composition and dominance of juveniles among the macrofaunal community suggest
that macrobenthic recruitment coincides with the timing of organic matter flux
so that the benthic community benefits from the sinking detritus.
