Present
study consists spatial patterns in biomass, abundance and composition of
mesozooplankton in Bay of Bengal. Surface
samples were collected from a central open ocean transect along 88ºE and
western coastal transect during the 2005 winter monsoon. During the sampling
period, both sea level- and sea surface temperature anomalies inferred from
satellite imagery were the lowest at the southern stations of the western Bay
transect. These anomalies coincided with the highest biomass and abundance of
zooplankton, of copepods in particular. Western region was richer in biomass
and abundance compared to the central waters. Zooplankton community comprised
28 taxonomic groups. Predominant copepod community exhibited low species
richness with just 46 identified species. They were evenly distributed over
stations and their diversity did not vary much between oceanic and coastal
transects.

Copepod
Undinula vulgaris was common in the oceanic waters and Temora
stylifera in the coastal. This study highlights the occurrence of pockets
of dense zooplankton biomass in the moderately productive (primary) bay.
