| 1 | Composition and abundance of epizooplankton in Bay of Bengal off deltaic Sunderbans, India The nature, composition, distribution and variations of the surface zooplankton in the lower stretch of the Hooghly Estuary, Sunderbans, West Bengal, India has been described. Surface zooplankton samples were collected at fortnightly intervals from the five experimental stations during high tide in the forenoon. Water samples were also taken for the determination of hydrological parameters. Hydrology of Hooghly estuary is found to be highly dynamic and characterised by large amount of precipitation. Hydrological parameters change from season to season. Biomass of zooplankton showed a higher value in comparison with the numerical value of the total fauna. Spatial and temporal distribution of zooplankton showed definite seasonal trends associated with environmental fluctuations Source: Sarkar, S.K.; Singh, B.N.; Choudhury, A.

| 2 | Studies on epipelagic zooplankton with special reference to copepods in Hooghly and Saptamukhi river waters, West Bengal, India Sagar and Prentice islands (West Bengal, India), two typical Gangetic deltas, are situated in Hooghly-Matlah estuarine complex which embrace deltaic Sundarbans with its luxuriant mangrove vegetation. Being a part of tropical estuary, habitat of Hooghly Matlah estuary changes with the variation of temperature, salinity, dissolved oxygen and pH which influence profoundly, in turn, organisms inhabiting estuary. Copepods constitute major bulk of zooplankton and occupy important position in tropic structure and play a major role in energy transfer. Among three sub orders of copepods, calanoids are the most numerically abundant group followed by cyclopoids and harpacticoids. Studies reveal that these areas are highly productive and act as nursery ground for different organisms. It has also been observed that the surface plankton community well responses to intensity of light Source: Kundu, S.K.; Sarkar, S.K.; Choudhury, A.
