Abstract

Climatological changes in the coming decades most likely will alter compositions and abundances of zooplankton. What we need to rapidly and comprehensively assess polar, boreal, subtropical and tropical regions and communities is automated instrumentation with which longer time-series and frequent coverage are possible. Such long-time series could be obtained from an Ocean Observatory (Wiebeet al. 1987). These field studies need to cover processes over scales from seconds to decades, especially to distinguish between natural variance and that created by climatological changes. Characterization of small-scale individual behavior,the vast majority of process studies on marine zooplankton in the ocean or in the laboratory have been on populations in assemblages and communities. No individual zooplankton organism has been studied over any extended period of time in the ocean or in a community like Coringa Estuary. Thus, the distribution and behavior of zooplankton at the level of the individual organism, and their importance to biological and chemical processes in the ocean or in actual study i.e Coringa are largely unknown. Large scale conversion of mangrove areas for Industrialization particularly oil and gas exploration ,practice of brackish water fish farming and shrimp culture in the area has not only rapidly depleted the valuable mangrove resources but also impaired the ecological balance in the estuarine ecosystem there by depleting Zooplankton communities. In the present study an attempt has been made to give a detailed account of the Zooplankton of the coringa river of Coringa wild life sanctuary
