taxonomic group as well as using early references from the study area.
Different departments of Central Marine Fisheries Research Institute,
National Institute of Oceanography and Marine science division of CUSA T
played significant roles in the confirmation of species. The species with
only one individual under the particular genus was denoted by "sp." and if
many species present in the same genera were denoted by "spp.". The
identified samples are kept at Central Marine Fisheries Research Institute
for any further reference.
2.6. Benthic productivity estimation
Organic carbon equivalent for the benthic biomass was
determined by the procedure of Lie (1968) and productivity estimates were
made as per the methodology of Sanders (1956) and Crisp (1979).
The annual benthic productivity was calculated from the wet
biomass as given below.
