| Abstract: | Quantitative assessment of macrofaunal
community of Ayeyarwady continental shelf, Andaman Sea
was studied during the coastal resource survey during April-May 2002. About 27
major taxa were identified. Abundance of fauna was in the order of polychaeta
(34.2%), crustacean (25.7), mollusca (4.2%) and echinodermata (4.5%), forams
30.3% and other groups 1.1%. Faunal density ranged from 59 to 6027/m2
and the wet weight biomass from 0.01 to 43.47 g/m2. Funa was
dominated by polychaeta with 100% prevalence. Faunal composition differed along
the depth gradient of habitat heterogeneity. Macrofaunal abundance during this
study was within the range reported for shelf water of Burma and Andaman
Sea but were higher than those from
the South China Sea. Major shift in the
quantitative distribution and spatial heterogeneity was due to several
environmental factors. |
